New ‘Polar Grit X’ Caliberates, On Par, With My ‘Garmin Fenix 6’.

Polar Grit X ‘all black’ at LEFT.

My Garmin Fenix 6 has the Titanium Bezel.


When in ‘smartwatch’ mode they are very DIFFERENT.
Like chalk & cheese.

I wore the new Polar Grit X next to my Garmin Fenix 6 yesterday & today during my 4.5+ mile walk/hike/run.

As you can see from the top 3 pictures the distance & time were on par with my Garmin Fenix 6.

I can’t say which one is more accurate, but I know that the Garmin Fenix 6 is ‘OK’ — in that I have tested it against multiple other watches, including the new Fitbit Charge 4 (just a couple of weeks ago).

If the Grit X readings had differed widely I would have been concerned. They did not. They stayed within ‘spec’.

This was also true for the elevation & Heart Rate (HR) data. The Polar & Garmin were pretty close to each other.

So, that is good. That is a start.

I will publish more pictures and data soon.

This was a first cut after having the Grit X for 2.5-days.

Polar’s ‘Nightly Recharge’ (On The New Ignite) vs. Garmin’s ‘Body Battery’.

by Anura Guruge

They are both basically trying to tell you how well your body is coping and recovering from stress (BOTH physical and emotional).

Garmin with its ‘Body Battery‘ (which I have on my MARQ Expedition) does it over the whole day.

Polar with its ‘Nightly Recharge‘, per the unambiguous name, focuses on your nightly ‘recharge’ — with the emphasis on the early part of your sleep.

Polar’s ‘Nightly Recharge’ definitely gives you more data than I get with the Garmin, e.g., breathing rate, heart rate variability and beat-to-beat interval. (See images below).

Garmin’s ‘Body Battery’ feedback on Garmin Connect.

Polar’s ‘Nightly Recharge’ status on their APP.

As you can see from above, there are TWO aspects that are taken into consideration: autonomic nervous system (ANS) recovery and how well you slept.

ANS Feedback

The Sleep feedback which is not that dissimilar to what you can get with a Garmin.

The Garmin MARQ Expedition & Polar Ignite side-by-side on my wrist. NO, I do not wear them together. Would be overkill. This was just for the photo op.

It appears I am doing OK. I could have told you that without either the Garmin or Polar! SMILE. I sleep like a LOG. To say I sleep like a baby would be wrong. As a father of four I know that babies are fussy sleepers. I am not. I fall asleep fairly easily and when I do, I am GONE. I sleep deeply as far as I am concerned.

There is a very good reason as to why I sleep well. I am dead tired by the time I go to bed … usually after 1am in the MORNING. I also don’t get as much sleep as I would like. 8 hpurs would be a dream. 7 would be nice. I usually end up with something less than 7.

As long as I get up at my usual time, which is past 8am, I wake up RESTED and ready to go.

So, both the Polar and Garmin are basically confirming this. I sleep OK and am recharged when I get up.

Would be interesting to see what others get in terms of readings.

The New Polar ‘Ignite’ & My Garmin ‘MARQ Expedition’ Side-By-Side On My Wrist.

by Anura Guruge

Click images to ENLARGE.

I was sent an ‘Ignite’ — Polar’s latest smartwatch — for evaluation. I just this very minute started wearing it after putting away my Garmin ‘MARQ Expedition’ (carefully wrapped in soft cloth). I have been wearing the MARQ non-stop (bar when charging it) for 43-days since getting it on May 20, 2019.

The back of the ‘Ignite’ if nothing else is ‘busy’. The four shiny contacts are used for charging. But, I am not sure whether they also play a role in heart rate (HR) monitoring per Polar’s supposedly innovative ‘Precision Prime sensor fusion technology‘. I am curious whether Polar does a better job at HR monitoring than Garmin. I will endeavor to find out.

November last year I did try out a Polar Vantage V for a couple of weeks. That supposedly had the same HR technology and I can’t recall seeing any HR data that was that far different to what I was used to with my Garmins.

The Ignite looks like a diluted Vantage V. We will see. Stay tuned.

Always fun to try out news watches. Yes, I am lucky being able to do so.

‘Fitbit Inspire HR’ Heart Rate Readings Par With My $750 ‘Garmin Fenix 5 Plus’.

by Anura Guruge

Click to ENLARGE.

Last night I started wearing my Garmin Fenix 5 Plus alongside the Inspire HR to see how the readings matched up.

I checked the heart rate (HR) on a pretty regular basis.

The Inspire HR heart rate was always with +/- 5 beats per minute (bpm) of the Fenix 5+.

That +/- 5 b

pm variation is GOOD. Very good.

Neither the Fenix nor the Inspire HR measure HR ‘non-stop’ so to speak. They read it a few times each minute. Maybe once a minute. That is to save battery life. So, there is no guarantee that they are both reading my wrist at the same time. What I did observe is that the Inspire HR always catches up to the Fenix within 30-seconds or so.

I have had (and worn) a Fenix 5(+) for nearly a year. I have checked its HR against multiple other devices: blood pressure cuffs, oximeters etc. I even got a nurse to check it last August. She was impressed. Said the Fenix 5 readings were within the range they consider ‘more than acceptable’.

I was impressed. $750 watch vs a band that costs $99.95. Just wanted to share that with you.

Per My ‘Garmin Fenix 5 Plus’ I DIED Twice, In My Sleep, Last Night.

by Anura Guruge

Click to ENLARGE.

I did NOT wake up dead tired. So, I have to assume that dying isn’t very tiring — and, of course, also the resurrection. Didn’t feel a thing.

I did, however, extremely atypically, oversleep by 20 minutes. I do NOT (contrary to what Garmin Connect thinks) use an alarm. I get up when I get up. Usually it is between 8:40 to 8:55 am. I am like clockwork. Not this morning. Strange. My body must have been compensating for the time I was dead.

As the chart below shows I am NOT new to Garmin. I check my heart rate FIRST THING each morning — just to make sure that I had not died.

This is the first time I have seen that I died. Kind of cool.

Yes, I have a depressed heart rate. Yes, part of that is drugs — legal ones, in particular MIRACLE-DRUG Toprol XL which I have been on for 20+ years. Plus, as befits someone in the TOP 99% of floor climbers I am reasonably fit.

My sleeping heart rate does go below 40. I have seen 32. But, never ‘ZERO’.

No, I do not have sleep APNEA and my BMI is definitely lower than that of Donald Trump. Promise and Mexico did not pay me to say that.

So, …..

My adoptive mother died in her sleep when she was 62. No symptoms. Nothing. Just died in her sleep. She was 62. I am 65. But, we do not share any genes (and she never wore jeans).

Interesting. Does not bother me. Dying in your sleep is the best way to go. So, I am cool with this.

Let’s see if I die again tonight. No, I am NOT going to think about it, BUT I bet my resting heart-rate will be up.

I was working it out. I died TWICE. So, I am now in my THIRD-COMING. Maybe I should start a cult.

Don’t wish me anything. Let nature take its course.

‘Huawei Watch GT’ An Attractive GPS Smart-Watch Not Officially Available In North America.

by Anura Guruge

Click to access ‘Huawei’ product page with their video.


Click to ENLARGE.

Like the ‘Amazfit Verge‘, which I am currently evaluating, this is another impressive Chinese GPS smart-watch with a compelling AMOLED display. It is not Huawei’s foray into smart-watches but it is by far the most feature rich, in that it includes: GPS/GLONASS/Galileo, continuous heart-rate, VO2 max, sleep monitoring etc.

That it is currently not officially available in North America is rather frustrating. Yes, there are folks selling it in the U.S. — and it is available on eBay — but there is no U.S. warranty and Huawei is very explicit that it is not available in the U.S.

From the specs., I think it is more capable than the Amazfit ‘Verge’. But, the ‘Verge’ is now available in the U.S., even from Amazon, whereas the ‘Watch GT’ is not. That is a shame.

Ever Stylish ‘Withings’ Joins Apple In Offering A Smartwatch With On-Demand ECG/EKG Heart Monitoring.

by Anura Guruge

It is not as fancy, nor expensive, as the Apple Watch 4, but it looks good, has fixed analog hands and claims to have a 1-year battery life. But, it is not due to be available till the second-half of 2019 and does not have built-in GPS. I am also not sure whether it does Heart Rate outside of doing an ECG. Hhhmmm.

Without GPS, any Withings is not for I. Shame. I like their look and the battery life is taking things to a whole new dimension (and I write this while charging my Garmin Fenix 5 Plus).

Appears that Withings needs FDA approval before they can release this. I will try and keep you posted.

This was announced at ‘CES 2019‘ that is just starting.

Without Heart Rate It Is Meaningless To Compare ‘Casio Protech’ To ‘Garmin Fenix 5’.

by Anura Guruge

Click images to ENLARGE.

I happened to see the ‘Gear Petrol’ article in my Google News feed and was intrigued to see what this competitor to the Garmin Fenix 5 (Plus) was. A Casio? Wow.

I used to, in the 1980s, be a big fan of Casio though I honestly can’t remember whether I ever owned. I am sure I must have.

While I knew Casio continued to make ruggedized, outdoor watches I did not think they were in the same league as a Garmin Fenix.

So, I looked and did some quick research. Though Casio does make some ‘inexpensive’ watches with Heart Rate (HR), HR is NOT available on the Pro Tech line.

Without HR it is NOT a FITNESS tracker. Just a smartwatch with GPS.

But, Casio has the resources, smarts and drive to get that right. So, as of now I am going to keep an eye on Casio. I suspect that by this time next year Casio may have a watch that is as good as today’s Garmin Fenix 5 (but probably not as good as the ‘Plus’ in that it is unlikely to have music).

So, stay tuned.

Garmin Adds ‘Abnormal Heart Rate’ Reporting To Its Major Wearables.

by Anura Guruge

Click to access full post on the OFFICIAL Garmin blog.

Click to ENLARGE and read here. From the Garmin Fenix 5 Forum.

This, from what I have read, for a much sought after feature on Apple Watches. Some were buying Apple JUST for this feature and you may even have read a few stories about folks crediting the Apple Watch of saving their lives by notifying them of abnormal heart rates.

So, Garmin had no option but to respond and it is good that they have done so now … ahead of the new wave of watches that are supposed to be announced by the likes of Samsung over the next few months.

Right now this abnormal heart rate feature is available on: Forerunner 645(M) & 935, Vivoactive 3(M), Vivosmart 3, Vivomove HR and Vivosport.

It has, as you can see from the second image, on the latest beta software for the Fenix 5.

It is not a feature that interests me but I know that many of you will be thrilled. So, go for it. All the best.

Bulova’s Latest ‘Precisionist Collection’ Watches Have A Rugged Charm To Them.

by Anura Guruge

Click picture to ENLARGE.

There might have been a time that I might just have considered wearing one of these — but not anymore. Appears that I am destined for ever onwards to only wear high-end activity/sleep tracking smart watches with GPS/Glonass, Heart Rate Monitors and gyroscopes. But, I don’t mind looking. As I have mentioned before Bulova sends me e-mails and I check out what they have to offer.

The ‘red’ version does have certain je ne sais quoi. Does look kind of cool. They all, however, look heavy
