Garmin 920XT and running Dynamics

Got new life insurance and the company i am with offers 50% off on garmin products and as I am such a gadget head i decided to buy the 920XT which is also useful for swimming besides my normal running and cycling.

The watch itself maps other data that i was not familiar with so popped out this morning on a run just over 10km to explore what the running dynamics mean.

Running dynamics give a summary

Screenshot 2016-04-17 15.46.35

Cadence i know is stride rate – quicker chi type running has always been my thing – i am not a long heavy impact strider … In general, more experienced runners tend to have higher cadence. An often-cited target for running cadence is 180 steps/min. So i am bang on target for this run.


First off is Vertical Oscillation

I was feeling stiff at first but loosened up after a km of running – this is where the data goes into blue – there are green spikes in sync with the downhill sections after that …

The colors show how your ground contact time compares to other runners. The color zones are based on percentiles.

Color Zone Percentile in Zone Ground Contact Time Range
Purple > 95 < 218 ms
Blue 70 – 95 218-248 ms
Green 30 – 69 249 – 277 ms
Orange 5 – 29 278 – 308 ms
Red < 5 > 308 ms

Garmin has researched many runners of all different levels. In general, more experienced runners tend to have shorter ground contact times. Elite runners often have ground contact times of less than 200 ms. Virtually all experienced runners studied have ground contact times of less than 300 ms. Higher cadence and faster paces are both associated with shorter ground contact times. Many running coaches believe that a short ground contact time is characteristic of a more economical running form. However, at a set cadence, decrease of ground contact time usually increases vertical oscillation.

off topic – watch design

Saw this blog and thought how interesting this change to standard design was. Most watches get complicated or expensive or tech. This appeals to the nerd in me and the travel part in equal measure.

Klokers 02

Klokers Watch Times 2, For the Nerd, and the Not Quite a Nerd

Klokers 03I first saw the Klokers Watch on their own web site, before it was launched on Kickstarter, and I was interested in the project.  Life being what it is, I did not have a chance to cover it right when it launched, but I did see that they received a lot of coverage, both from watch bloggers and from gadget watchers.  Now, with a little time remaining before the project closes, Klokers introduced a second model into the mix.

Klokers 01The first watch, the Klok-01 is an homage to a circular slide rule.  It is definitely a nerd friendly design.  I graduated from a tech-heavy university, and I grew up with calculators, but I am not far removed from the generations who had to use these instruments for calculations.  So for me, this is a fun watch design concept.  As a watch in and of itself, it is simply a clever way to do a three hand watch.  Instead of the hands rotating against a static time scale, the time scale rotates around a static single hand.  Because the time scale is moving, the discs have to move in retrograde, opposite the normal motion of a handset.  But the overall effect is a fairly simple way to tell time.

Klokers 02The second Klokers model, the Klok-02, was introduced half way through the funding campaign as an optional reward and is a distant cousin to the first model.  You have the same basic shape, as well as the curved, bezel free acrylic glass case, but the styling cues are less nerdy and more innovative.  A Soprod movement controls a series of micromotors moving the second hand and minute hand in a more traditional (watch world-wise) retrograde movement, where the hands move through an arc and then reset back to the far left once they make it all the way over to the right.  The hours are displayed in the center of the watch, and the window to the right represents the time zone.  Move to another city, and just click through the cities to change the time zone, an hour at a time.  A long push on the pusher displays the date in the center window.

Klokers 04As if the time displays and micromotors were not enough, the team at Klokers also came up with a new watch strap, where a tab locks into a slot on the back of the watch, allowing for easy strap changes, or easy watch head changes, whichever way you want to look at it.  The project has been wildly successful, with about $600,000 raised against a target of $56,000.  Super early bird watches are gone, but there are still early bird and night owl rewards in the low to mid $300s for the Klok-01 and mid $500s to $600s for the Klok-02.  It is hard to assess how feasible it will be to actually produce these watches at this price.  Both watches use existing movements, (a Soprod SOP 813 in the Klok-02), which means they are not inventing the watch technology, just packaging it.  With any crowd funded project, and especially with an innovative one, do your research.  Crowd funded projects by definition are not retail transactions, but rather the backing of the development of a project in exchange for a reward.

Watch Overview:

  • Brand & Model: Klokers Watch Klok-01 and Klok-02
  • Price: ~ $339 to $556 for the Klok-01 and ~$566 to $981 for the Klok-02depending on timing and options
  • Who we think it might be for: You want to fly your nerd flag (Klok-01) or you want something different on your wrist (Klok-02).
  • Would I wear one myself based on what I’ve seen?: I think I would make an exception to my automatic/manual only trend for the Klok-02.
  • If I could make one design suggestion, it would be: I like it as is.
  • What spoke to me the most about this watch: With so many watches, especially crowd funded watches, looking alike, these are truly different.

Tech Specs from Klokers:

  • Movement: Swiss Ronda Quartz with micromotors (Klok-01) or Swiss Soprod SOP 813 micromotors movement (Klok-02)
  • Functions: Three hander (Klok-01);  World time, date, retrograde minute and second hand (Klok-02)
  • Case: Composite metal and polymer
  • Crystal: Acrylic polymer
  • Water resistance: 5 meters (Klok-02)
  • Lug width: Proprietary strap connection
  • Straps: Leather

A watch if you spend all the time outdoors (and don’t want to scratch your rolex/omega/TAG)

I must admit although i like nice watches BUT (and its a big But) when i head out into the wild (or working in places like Iraq or Rwanda) I generally take along a G-Shock watch. This one does a lot in a simple package.


Casio announced a brand new high-end G-Shock model at Baselworld 2015, the GWG-1000 Mudmaster. This new model combines features of the Mudman and Rangeman with an analog/digital hybrid display. It has a case design that looks like a cross between an aviation G-Shock and the Rangeman, giving it a tough and tactical appearance. Model numbers are GWG-1000-1A (black), GWG-1000-1A3 (black with olive band), and GWG-1000-1A9 (black with yellow band).

Will the apple watch shake up the GPS and app market?

In addition to being a wearable emoji-sender, heartbeat-sharer, and payment system, the Apple Watch will also be a fitness tracker. And although the watch won’t be available until early 2015, Apple provided a few details on how the wearable will track activity. The watch has its own accelerometer and heart-rate monitor, but it needs to be paired with an iPhone to track your distance traveled via GPS or Wi-Fi.

These features are of note because they add a new set of functions to Apple’s hardware stable, and they directly compete with offerings from long-time hardware partners who already make fitness tracking wearables like Jawbone, Fitbit and Garmin.

The Apple Watch has some standard features familiar to the fitness crowd. Its built-in Activity app has three modes, all of which display goals in a ring-shaped interface. In the “Move” display, it shows you how much you’ve been in motion during the day, gives you a running countdown to your 30-minute goal, and shows how many calories you’ve burned. The “Stand” display reminds you to stop sitting for at least a minute every 12 hours (see the photo above), and the “Exercise” ring will gauge harder-core activities like running.


There’s also a separate Workout app that can break your activities into more-specific groups, such as Running, Cycling, or Cross Training. All your stats and workout history are stored in a Fitness app, which gives you a dashboard of your workout sessions. You can share your workout stats with third-party apps via the watch’s Health app, too.

Even though all of that is standard-issue stuff for a fitness tracker, Apple’s HealthKit initiative is likely to play a major part in making all that workout data usable by other apps on your iPhone, iPad, or Apple Watch. The software package for developers will likely speed the growth of the ecosystem of apps built for the watch—though Apple has been largely silent on details about how or when those third-party apps will make their way onto its Watch.


Suunto Core Alu

Although I have a Garmin Fenix I use for running and kitesurfing, i also have a suunto core which I love. but the first edition Core has had it’s issues the latest being battery problems so I have sent it back to Suunto.

(within six months it had munched its first battery, three months later it had got through two others so I pretty much forgot about it. Last month I sent it back to Finland under warranty, and two weeks later I got a refurb back (was made a month earlier than the one I sent in.)

This one lasted a week before exhibiting the same problems as my original one (blank display, no life) so it’s currently back in Finland again.

I’ve heard good things about the late 9xxx serials, and the 0x serials, so check before you buy – if it’s a 7xxx or 8xxx serial number, even an early 9xxx (try to buy later than 930x) then walk away.

Serials are Year, Week, 5 digit serial – a eg 949xxxxx is week 49, 2009.)


In the meantime i have a Suunto Core Black Alu to enjoy. Get yours here – if you buy one I get a whopping few pence as a thank you

Same Spec but nicer build

Suunto Core Alu watch, which comes in a variety of finishes, is a soup to nuts watch, though keep in mind it lacks GPS.  That short coming aside, it can measure the air’s temperature and tell if you’re heading in the correct direction thanks to the digital compass, which mind you automatically calibrates itself according to your surroundings.   In addition to that, there is an automatic altimeter/barometer switch, storm alarm with a weather trend indicator, altitude logger with altitude difference measurement, multiple date/watch/alarm functions, sunrise/sunset times for 400 locations, multiple language support, a user replaceable battery and a few different straps to choose from.

G-Shock Aviation Gravity Defier GWA1100-1A3

With a ton of truly impressive G-Shock’s hitting the market this year, one of the most interesting, durable and technologically advanced is the new Gravity Defier GWA1100-1A2.  I’ve had my eyes on this piece since we 1st saw it at the Basel Fair earlier this year.  After much anticipation the new G-Shock Aviation GWA1100’s are finally in stock, and look way more impressive than I remember.  I’m proud to say, I just picked this piece up for my personal collection, and want to explain why this was my “must have” G.

G-Shock Aviation Gravity Defier GWA1100-1A3

G-Shock’s are known for their durability and being virtually bullet proof.  This new Aviation model goes above and beyond the limits of not only other watches, but also pretty much any other G-Shock on the market today.  This model is Triple G Resist which means it is resistant to shock , centrifugal force, and vibration.  Utilizing the new Alpha…

Wakmann sailing watch


Wakmann Regate 1972

Is it actually possible to put any more on the dial of a watch?????

It is clearly marked Wakmann Watch Co on the rotor of the 1341 movement

It has a Regatta (or Regate) countdown between 12 and 3
The rest of that outer ring taken by a tachymetre
There is a month calendar, set using the crown at 10.30, so you set the day on the beginning of the month, and it tells you the days of the week for that month.
Of course there is the time and date.
Constant seconds
and a 12-hr chrono with the classic Lemania central seconds and minutes, leading to fantastic legibility.

The dial is a lovely brushed dark navy blue its sobriety somewhat accentuated by the more garish 70’s colours chosen for the calendar wheel.

It still manages to be very legible, despite the “crowding” of the dial.

I am beginning to like it more and more.


Garmin Fenix

Just taken the plunge and ordered this … Off to Istanbul for a month and will review the watch in the next week or so.

the Garmin Fenix

The Garmin Fenix is the first GPS navigator + ABC (Altimeter, Barometer & Compass) wristwatch to include comprehensive Garmin GPS navigation. Developed together with professional mountain guides and designed for the serious expeditionist and outdoor enthusiast, Fenix is the hands-free outdoor navigation tool that guides you with confidence through demanding mountain environments.
You can create and follow routes and mark up to 1,000 waypoints which you can navigate with ease. In addition Fenix can store up to 10,000 track points, recording a track log – a GPS “breadcrumb trail” – as you move. You can then use TracBac to show you the way home. Naturally, as a navigating GPS+ABC watch, it also includes altimeter, barometer, 3-axis electronic compass and temperature sensor. Rugged, stylish and waterproof to 50m, it’s also a functional, accurate, well featured timepiece, as comfortable for everyday wear in the city as it is off the beaten track.
More than just a navigational tool, the Fenix provides comprehensive real-time performance monitoring for athletes such as trail runners and ski mountaineers. With lap and autolap function and important performance data (e.g. distance, vertical speed and pace), ambitious mountaineers can keep track of their progress during their outdoor training activities. Equipped with ANT+ and Bluetooth, the Fenix not only shares data wirelessly with other units, it’s also compatible with Garmin’s optional premium heart rate monitor or speed/cadence sensor for distance, speed and cadence while on a bike.

Polar RCX5 review

The Polar HRM arrived nearly a month ago now and I have had a good chance to use it in various sports.

Firstly unboxing showed a nice little box and neat packaging. When you first switch on RCX it asks you to input basic things like sex, age, height, weight as well as the amount you exercise per week. I fall into a higher (amateur) category of roughly 5-7 hrs / week.

The RCX typically comes in 3 configurations … a gps setup which includes the excellent G5 gps. This is a very nice waterproof unit which holds charge for 20 hrs which is far from what i have had the pleasure of exceeding. The unit comes with an armband although I must confess that one month later i have yet to use it. The unit is very wee and fits into the small key pocket at the front of my running shorts as well as the back pocket of my running tights. I even used it the other day on a ride and had it jammed into a small front pocket of my jacket pocket. Being hunched over I expected the reception and subsequent track to be slightly skittish but coming back i compared the track to the one recorded by my Garmin Edge 305 which is on my stem with an uninterupted view of the sky. The comparison revealed that the Garmin recorded the ride as 51.42km and the edge at 51.62km … that is a 200m discrepancy over a huge distance. thinks it something like 0.4% (better get my calculator out) I am sure a shoulder mount or bar mount would make it perfect (that is me judging the Edge to be perfect …)

Other configurations are the Run pack which comes with the S3+ stride sensor. I have not used this but have seen side by side comparisons to the Garmin unit and from what I gather they are pretty compareable. The Polar unti is much bigger and does everything the Garmin does … the only feature useful to me would be the stride count … but then i am a slight Chi runner and my footfall stride is roughly 83-85/min.

The other configuration i have seen is the bike pack which has a cadence and Speed Censor … the cadence sensor would be the most useful to me … if you have the GPS sensor then i think you dont need the speed sensor.
One point I would say is that it is a shame that it is not the one unit like many of the competitors now do. Times and Garmin do their combined ones. I still use my Garmin unit along with the edge indoors when on the turbo trainer and having this placed on the back wheel makes it very practical.

I think that all the above configurations come with a heart rate belt although it is also possible to buy the RCX5 unit as a standalone piece which is probably only something that athletes that already own a polar belt (although not all older belts can be seen by the RCX5) On the heart Belt itself – amazingly comfortable and using Garmin and Suunto for the past few years I must confess that Polar know what they are doing when they make the belts … so comfy and you never get a strange spike or weird reading that you sometimes get with the Garmin HR belts.
Polar also do sports bras for women which have the HR receiver built into them which should make them more comfy than a standard setup for some.

what works with what POLAR

Back to the RCX unit. There are two colours to choose from a black and a red … I chose red because everyone knows that red is faster.

The square design has been criticised by some but I think it is great … it is slightly larger than a normal watch but once exercising the display is clear and very easy to use.
You can customise the display to show what you want to see .. I have gone into this before HERE

Using the Unit
Strapping the RCX on I immediately noticed how comfortable the watch was – in fact the whole construction oozes class not something i have noticed in the build of any previous Polar, Garmin or Suunto with the possible exception of my Suunto Core

Going outside for a run you can leave the gps on a wall whilst you pre-stretch – and then it latches onto the signal very quickly – the chipset inside the unit is a SIRF6 which allows for quicker lock on. the given wisdom is that cold fixing (in an area you have not been in before) will take around a minute, and hot fixes (starting in an area where you finished your last run / ride) will take 10-20 sec. From experience this seem to hold true. Of course this is a gps so switching it on when inside your house will not be good … but a sky above you should be good enough for the fix.
A tip I learnt for cold or rainy weather is to switch on the gps and leave it in your window whilst you put shoes on and it is generally ready to go when you are.

The unit when setting it up can be set to auto-lap – this is something I use when running having the watch perform every 1km … i find this more useful as a pace guide and a very good nudge to the brain when i need to speed up.
the watch can be set to either follow a programme (which can be configured on polar personal trainer and downloaded) say if you were doing intervals with a 5min warm up, 10 min tempo and 3 fartleks then arm down. The watch also has a great audible warning which can be set to pace or HR. This can either be set to Loud, quieter or off. I find this more useful when doing a fat-burn ride or run when my natural instinct is to speed up and defeat the very purpose of the training.

Post exercise the RCX5 stores your last exercise in the data section fro you to review. By itself the RCX5 gives a good breakdown and review of data. You can look at individual training sessions or see a summary of the week which is useful if you need a motivator to get out the door for a run or cycle. One of the good features is that there is a very good heart rate zone breakdown as well as a neat thing were you can see what percentage of calories was in fat burn.

HR zone breakdown

Speaking of features there is something missing and that is a proper barometric altimeter. Most of the course I do aren’t that hilly and I put bike tracks into bikewithgps or other tracking websites which recomputes gps info and produces a ride profile. For those running in hilly location this lack of altimeter might be a problem but for me it is not a deal breaker.

I think the beauty of the Polar RCX5 is in the heart rate monitoring … a lot of people like myself would look at the lack of ANT+ support and the very annoying lack of integration with other platforms like map my run, bikely,endomondo and others and decide not to go with polar BUT (and it’s a big butt) polar does and has always done great heart rate monitors. The analysis that you can do post exercise is way better than polar and a bit better than the hrm software that my old suunto t6 used with movescount.

Once you have done the exercise you can upload the data using polar weblink which is a free download from their site. One word of advice make sure you click the RCX5 for PPT option as I inadvertently clicked the other option when downloading the update then tore my hair out trying to figure out what i had done)
With the Polar Personal Trainer software you can create programs as well as seeing very easily how your training load is…. This prevents you overtraining (however rare this is in my case)

Finally I would say that polar, although not integrating as well as Garmin does with ANT+, weblink does allow you to access the RCX5 and download the .hrm files and .gpx files (gps track) – it’s a shame it doesn’t use the .tcx format but i think that is a garmin proprietary format.

I may have highlighted some weaknesses in this review but I am happy with the unit and wouldn’t change it.

Bryton Cardio 30 ordered – to be reviewed soon

Interesting to see how the new upstart compares to others on the market.

Cardio 30

Cardio 30, the smallest GPS sports watch on the market, is for all levels of athletes. By setting goals in our pro-training programs, Cardio 30 can accurately calculate and record your location, speed, distance, pace, stride rate, cadence*, heart rate* and more. Your training results then can be shared and analyzed at

With built-in “G sensor”, no extra foot pod is needed for indoor exercise.

Obviously Garmin (with their patent infringement lawsuit) have their various Forerunners (which I found uncomfortable and too chunky) and Suunto with their T6C and Polar are main competitors … although Suunto/Polar have seperate GPS units which pair.

I wanted a system that worked on ANT+ so that my cycling and running as on one system …..

A review coming which will hopefully give more info and insight than the Bryton website.

Watch illustration with a meaning

Not quite the more modern G-Shocks I love but similar styling to 5600 series ….

You Can buy the artwork here

This work explores the variety of symbolism an object carries or has projected upon it. The aesthetics of this illustration are reminiscent of popular art movements or the illustrative styles of contemporary advertising; from a distance, it may well appear to be an advert. There are many possible individual relationships to this casio: for some it’s a form of nostalgia, for others a retro fashion item available in different colours to fit your personal style and outfits. But for US military operatives it carries an altogether different meaning… The United States military considers this watch to be “an indicator of al-Qaida training in the manufacture of improvised explosive devices (IEDs)” and with it the identifying feature of a potential terrorist. Bin laden himself had been photographed 
wearing one. 

This ubiquitous watch is readily available worldwide for around £4 at its most basic model and worn by many in the middle east and likewise around the fashion hubs of New York, Paris and London. A singular object, linking perhaps millions of people worldwide; each carrying altogether different meaning

Heritage Collection

The Heritage Collection: the quintessence of classicism in watchmaking


For over 175 years Longines has been the heir of a watchmaking tradition that was forged in the furnace of elegance and precision. Over the years the brand has played an important role instilling classical beauty in watchmaking with regard to both pocket watches and wristwatches. By virtue of this rich watchmaking heritage Longines has created a line of watches called the Heritage Collection. This collections pays tribute to the historical creations that have an aesthetic quality which has since become classical and essential. While some timepieces remain as evidence of a production that more or less excluded the wristwatch until the end of the 19th century, the Heritage Collection contains principally models intended to be worn on the wrist. The Elégantes de Longines line, inspired by the Art Deco movement that was characteristic of the 1920s and 1930s, pays a subtle tribute to the elegance of ladies’ watches. The Présence Heritage line focuses on the classicism of the pocket watch that has been adapted – with just a touch of nostalgia – to be worn on the wrist. The Conquest Heritage, Silver Arrow and Flagship Heritage lines offer models that celebrate the golden age of traditional mechanical wristwatches, a period when Longines competed to set certain stylistic standards with regard to timepieces.
