Hi Zaki! Thanks for the comment. I think each with each design, hardware and software things can change. I also hope my testing is getting more rigorous and my standards are becoming higher.

Congratulations, great review. I am a PhD student in exercise physiology, and typically also we test the smartwatch or sportwatch (garmin and polar) in the our laboratory, HR with polar H10, or with the portable metabolimeter cosmed k5 to compare the estimate of vo2max that watches make, as well as steps and gps signal with pace in min/km, or for the comparisons of ventilatory thresholds.

[@dharambasi1928]

Huawei have historically been good with their accuracy. Somehow they messed up the more premium Watch 3 but it's good to see them come back with the GT3. They're doing really well considering the lack of Google services and massive loss of revenue. HarmonyOS is very promising.

[@carlosmobellan9443]

Hi Rob, thank you for your comprehensive review as usual. In relation to GPS acquisition, I was not very clear on how you went about this. Generally speaking, in my experience, if a watch does not pick up GPS acquisition immediately and you then take off on your ride (or run, whatever) it will not pick up GPS acquisition until much later if at all. I recall DC Rainmaker has confirmed as much in his reviews of Garmin and other units. I would wait for the GPS acquisition standing still or perhaps walking in a short distance or loop from your start point if you think that will help. The real issue with GPS acquisition is time taken whilst standing still; that can depend on the watch and in particular whether the watch has GPS cacheing. If it has GPS cacheing it should not take very long at all. I can't speak to the GT 3, but in my experience with the Huawei GT2e, i had no problems with GPS acquisition as long as a I waited (usually a short time). Hope that helps in the future. Cheers from Down Under.

[@alexpope51]

I bought one GT3 42 mm. I liked the way it presents the results (statistics, etc.), very well impressed by the precision of the heartbeat measurements at low range, up to 140 bpm (I compared its measurements against an oximeter / heartbeat monitor).

Thanks for the review! It's good to see that optical sensors start to perform better these days. Also, you've made a review of Venu 2 but what about making comparison of some well established device like Fenix 6 which also use FirstBeat metrics just like Venu2, but unlike Venu2 it has polished firmware. And Garmin seems to be infamous for releasing devices which has less than optical performance in the beginning.

Wow, thanks so much! Who else do you follow when it comes to smartwatches on KZbin?

[@dieu-trangvu4502]

I've worn my new GT3 to an outdoor biking session (1 hour) and a gym workout (also 1 hour). HR during bike ride was very accurate, on par with my Garmin Venu 2 (the graphs, average HR and max HR on both devices almost matched with only 1-2 beat differences). Unfortunately in the strength training session, after about 30 minutes the GT3 HR began to drop unexpectedly, then jumped up, dropped again. In general it behaved erratically in the lower end of my active HR range until 10 minutes before the end of the workout, where it started to pick up my (supposedly correct) heart rate again. In comparison, my old Apple Watch and current Venu 2 never had such a problem in a workout. I will try the GT3 again next week in the gym to see how it works

[@dieu-trangvu4502]

Hi, my update: the second time in the gym, I noticed when my HR started to drop and I tightened the strap around my wrist. It then read my HR much more correctly. I'm ok with the GT3 now, but still, I prefer the sporty look of the Venu 2S when doing workouts. :))

[@simdencard]

@@dieu-trangvu4502 I love the body battery on the Venu 2. Wish they had this on the GT3. So far I have used the GT3 since December as I got it as a Christmas present and the heart rate tracking seems good when doing weights. The reviews are good about the heart rate tracking so I'm happy with it so far. 😀

[@dieu-trangvu4502]

@@simdencard Me too, I'm happy with the GT3 now. I find that HR accuracy depends a lot on the fit of the device, and once it's solved, no more complaints. Its sleep tracking and training recovery features leave something to be desired though. I feel that it doesn't "know" me as well as the Venu 2. But I'll give it more time.

[@simdencard]

@@dieu-trangvu4502 Same here. The GT3 has worst sleep tracking than my Huawei Band 6 or Huawei Watch Fit. It seems to not be as sensitive so sometimes doesn't track my full night of sleep and only tracks correct for half the night.

If you tighten the watch to you wrist it will be spot on. However, I agree with you that when the watch is loose the HR goes up and down. That said, the GT3 is easily one of my favourite smart watches and one of the best looking in the market in my opinion.

Great review, thank you! Something I would be interested in as far as GPS accuracy goes is how accurate the distances measured are. I have a GT2e, and my daughter has a GT, and we found they consistently measured lower distances than my Suunto Spartan Sport WHR - typically about 2 to 2.5% for the GT2e and 3% for the GT. This included running on courses; the Parkrun courses are measured with a measuring wheel, and the GT2e would usually only measure 48 to 4.9km on the 5km course.

[@TheQuantifiedScientist]

Hi! In the end I would want to know what artifacts the GPS shows, which in turns tells us if it will likely predict too long or too short routes. If it loses signal a lot, it will likely track to short a route; if it is very noise, it will be too long. But those are just my first thoughts😊. Have a great day!

Hello Rob, what wearables do you wear day to day, when you're not testing something new?

[@zakialbetiyan449]

I'm looking forward for a summary video for your effort.. like the top 10 or 5 most accurate wearables

[@TheQuantifiedScientist]

Hi Zaki! Yes, that is planned! 😊

[@louis7186]

Thank you SO much! Amazing video yet again! Would love to see a fitness and activity award video! Kinda like Marques Brownlee smartphone awards. Best budget tracker, best heart rate & best sleep tracker! Just a though! Keep up the great work! 👍

[@TheQuantifiedScientist]

Great suggestions Louis! I was thinking about something like that actually. I'll check out how MKBH did it

what about the huawei gt runner, seem like a good watch

[@tobias1752]

Hey Rob, I really appreciate your content, wearing the iWatch7 or my old Fenix 5.. Now I‘m waiting for the new Garmin Epix2/Fenix7… and looking for the Circul-ring.. do you know anything about the ring? It’s made only for sleeptracking..

Happy i have gt3 today snd watch your review

[@TheQuantifiedScientist]

Happy to hear that LV! How are you liking the watch so far?

[@janthenasoy8366]

Hi. Can u compare or review also the Huawei gt runner?.. Though they have same sensors. Tnx.. 😁

[@shrifeazmy184]

Hi Rob, thanks for the video. You are the reason why I stopped using my galaxy watch 3 in my weight lefting heart rate monitoring because I realised all smart watches are not that good at this and I'm really concerned with accuracy, so, I bought polar H10 based on your recommendation and it's perfect, but now that I can get this android compatible smart watch, do you think I can replace my H10 and get same accuracy? Because a smart watch in gym I found it more practical than the strap

[@TheQuantifiedScientist]

Hi! I think the GT3 is one of the best optical heart rate trackers I've tested so far. However, for the very best heart tracking in the gym, a chest strap is still superior. However, the GT3 comes close in most cases it seems.

[@saiforos7928]

great presentation! love it. Though have to say it's important that you don't overextend yourself too much, you're releasing so much content already

[@f10r1n]

@TheQuantifiedScientist Thank you for your great work! I know it's been a very long time since the review of GT 3, but do you happen to remember if during the tests the continuous heart rate monitoring was set to "smart" or to "real time" mode? I recently found that real time mode improves significantly the sleep tracking performance (with the downside of slightly increased battery drain), and it seems to make sense because in the so called smart mode there are time intervals of 5-10 minutes during the night when the heart rate data is missing. And less data should most likely imply less accuracy, I assume.

[@ichbinmazen]

Hallo and thx you for this review... I have one question though, can the GT 3 broadcast the Heartrate to other devices during exercises? For example to a bike computer, like the Wahoo bolt?

[@Ellias31773]

Good channel, thank God youtube recommend me this video. May I know what is the best smartwatches for SP02? Subscribed.

[@TheQuantifiedScientist]

Hi! Thanks so much 😊. Not sure which is the single best watch for SpO2. The Apple Watch series 6 did quite well, but the series 7 still needs to be tested. An alternative is to buy a finger pulse oximeter, since these are not that expensive. Have a great day!

[@Ellias31773]

@@TheQuantifiedScientist thank you so Kuch for the reply, I do have an finger pulse oximeter at home but looking for a smartwatch that can do it all the time. Good day

Hi Rob, how many Stars would you give the GT 3 and would you recommend it? Thanks a lot for you serious work and keep going

[@hectorsanabria45]

You are awesome. That testes are so important, could you please test the accuracy for the Samsung galaxy active 2 or the watch 4, that would be awesome, thanks!

Thank you very much! Think I'll buy it to use on my swimming training

[@yber15]

I've got a question about the heart rate monitoring. Did u test the watch with heart rate monitoring set to 'smart' or did u set it to 'real-time'? I just bought the 42mm version of this watch and I'm wondering if there's a difference in the heart rate accuracy between those two settings. Thanks in advance!

[@anosvoldigoat3351]

Differences is one drains battery faster The 24/7 keeps the sensors switched on even when not wearing the watch The smart turns off the watch when you unstrap it and keep it aside like before going to the shower or something both have the same accuracy

Concerning step counting: How did you measure. Simply by the GT3 or in addition to your phone?

[@rolandrohde]

Thanks for the Review! It seems I chose the right Device as a Christmas present then since I was mainly after good heart rate tracking! Pity Huawei seems to have dropped the ball on SpO2 though...but I don't rely on those values anyway. One little thing...the new video style still needs some work IMHO...the switching Video perspectives and the little face displayed while talking about the measurements...well...to me they are more of a distraction than an improvement...but at the end of the day it's the content that counts and that is still excellent!

[@zakialbetiyan449]

Do you use it with android phone? If yes how do you manage to sync to third-party apps like strava and my fitness pal?

@@zakialbetiyan449 I use it with Android, but I don't sync with any apps apart from Google Fit. I have the app health-sync to transfer to Google Fit...works perfectly just like it did with the Garmin Vivoactive I had before.
