May I suggest to retest this same watch with a normal strap, and retest this expensive strap with a grey ultra 2?

[@derksenjenny]

I would advice this band for daily use not for workouts. I have no problems with my measurements just use a fabric band. And this beautiful band for the office. The problem isn’t in the black coating nor the watch its the fit of this band

[@Oli-o1s]

I'd advise not buying or wearing it ever. Cost to apple is $5-6. Retail is $200. You can get virtually identical ones for $30-40.

I think it's worth to make a complete ring comparison video - Oura ring 4 Ringconn gen 2 Galaxy ring Ultra human And you can wear them all at once with the right sizes, and do 1 exercise while measuring for 4 devices... The ring market is growing with new products and people only know about oura ring, we need you 😅 I pre-ordered ringconn gen 2 from kickstarter to wear in day to day, while i use Huawei watch fit 3 only for sports tracking with it's accurate heart rate tracking and unkillable battery :)

[@thisisfabiop]

Please test it with a different strap! Is it a matter of adherence or something wrong with the new Ultra 2 Black, even if supposedly the same of your already tested Ultra 2? Only another test would tell. Also, it would be interesting if you could also test the ECG function during your Apple Watch tests, since I've experienced quite a few times the watch not being able to perform the analysis.

I was going to ask this question! Obrigado Bruno ;)

[@LightningSnake]

Yes! But it is taking longer! Why is that?

[@OvidiuBosancu]

I have an AWU2 Titanium purchased with the Trail Loop strap. I noticed that, due to the Trail Loop, the watch moves quite a bit during running, even though it was fairly tight on my wrist. Because of this, heart rate measurement fluctuates a lot during activity. So, I decided to try the Ocean Band, and I was right: it fits much better and stays more secure on the wrist during running, resulting in a much more stable heart rate. I tested it against the Polar H10, and the values are very similar. For this reason, I no longer use the Polar H10 and rely solely on the heart rate readings from the AWU 2. In conclusion, I believe the Ocean Band is the most suitable strap for running, gym, etc.

[@TheQuantifiedScientist]

Thanks for sharing Ovidiu!

[@selimcanpolat8664]

i have to agree. i guess the ocean band distributes the weight of the watch more evenly, despite being the least comfortable band

[@EricA0321]

What’s your recommendation. I had an Apple Watch 7 but I can’t stand the horrible battery life. I want a watch(mostly) that are good for both sleeping and running that I don’t need to charge at least in 3days. I’m not a fan of subscription models..

Garmin question. I see the FR165 accuracy doing pretty good on the list compared to FR965. They both use the same elevate V4 sensor. Is it because the firmware was newer on the FR165 compared to when the FR965 was reviewed?

Thx for asking, and thx @TheQuantifiedScientist for answering. Don't want to order before a review from Rob :)

[@u.d.7543]

It's not about the weight, to make correct measurements, the sensors should be in contact with the skin all the time. Metal or silicone straps are not as good as elastic straps to keep the sensors in contact with the skin. This guy should test all the watches with the same elastic straps, otherwise it's not a good comparison. I told him many times in the comments before the strap is very important for the results.

[@Trump2024TheOrangeHouse]

he did this entire report is simply about this band, which is very helpful if you’re deciding to get this band, look at the previous ultra watch two review I think I will just use the elastic band when I’m exercising and use the metal band when I’m not this video was fantastic because it answered the question that I had wondered about this metal band

[@edismehmedali4666]

People rarely buy a strap, most people just use the strap the watch came with. So your comment is misguided

[@joseguzman6988]

@@Trump2024TheOrangeHousemy takeaway is that the strap you use can heavily influence your results with the device and be careful what strap you use and how it impacts the sensors

[@thaibinh99]

I have no intention on using my Natural Titanium Milanese Loop band while doing workouts, it will be used only for casual or formal events. The sport loop or something similar will be used for workouts and I think Apple expects the users of their Ultra watches to know the difference.

[@daanyaalali3089]

Does this apply to Milanese straps for the regular 10

[@The.JZA.]

To each their own but I wouldn’t use the titanium Milanese loop for exercise. It’s a classy watch strap for day to day wear or if you are going out. It’s an accessory to “dress up” a sport watch. For actual exercise, I think the trail loop is the best strap unless you’re swimming.

[@Ryzn322]

I think you should redo the test with an elastic strap. Non elastic straps loose skin contact which is essential for accurate hear rate readings, so the results are not surprising but also not fair.

[@Aus2312]

Did you test the other Apple Watches with the metal strap? If not, seems like the data here is flawed since the test is not like for like. I'd like to see a review with a standard watch band.

[@TheQuantifiedScientist]

I did a few test already of the Ultra 2 with other bands :-). The point of this video was to see if the new premium strap released with the Ultra 2 would give similar results.

[@mangatmangat6520]

During weightlifting 0.94 is really really good and I’m very happy with my black Apple Watch Ultra 2. My other watch Garmin epix pro gen 2 can not detect heart rate it shows me super low all the time unless I use external chest HR strap but Apple Watch detect very good heart rate and accuracy without any external HR sensor.

[@dawidjermak1237]

While I love Apple Watches for their accuracy of measurements (I have used them since Gen 3), AirPods for their great sound, I can't understand many of Apple's other decisions, such as the one with the strap you're presenting - to me it's a heist on consumers' cash. After Apple cheated me by locking my iPhone and Apple Watch (and they didn't unlock it, despite providing the original receipt) I stated with pain in my heart that I will never buy any NEW product from Apple again in my life. As always, great video, I love watching them. I envy the opportunity to run around the Belvedere gardens, Vienna is one of the most beautiful cities in the world :)

I advise you when wearing the Mi Band 9 watch to put on the nylon strap with Velcro. So that it is tight when closed and at the same time does not tighten your wrist. You can control its size very precisely.

Interesting findings, thanks !

[@ForsakenSparrow]

I find is a bit dishonest to conflate "Apple Watch Ultra 2 BLACK" with "AWU2 black with milanese strap", given that the strap likely is the important variable under test rather than the watch itself. If you are going to compare it with Apple Watch 10, you should a milanese band for the Apple Watch 10 as well. Apple themselves just mention that the Ultra milanese strap has a diving heritage, so that would be the sport context to test it in if anything. But probably people should view it as a lifestyle strap rather than a sport strap and judge it on those grounds.

[@TheQuantifiedScientist]

Hi! Thanks for the comment! I tried to be very clear in the first seconds of the video that this was about the strap. I already made several videos on the Ultra 2 with other straps. You can see it in the overview plots as well. Apple made quite clearly announced this new strap in the release event, so I wanted to look into it (because I was curious myself)

[@trumptman]

So weight plus the band choice can make even a great HR sensor questionable. Also I still see no methodology applied to make sure the HR data points are matched one for one with the strap in the event the Apple watch fails to report a value. Apple Watch will often just not show anything if the HR is having any concerns vs reporting late or a low/high. We should be told how many data points for the HR strap and how many reported for the watch.

A valuable video, or better said: a money saving vid. I think the strap is sold mainly for looks. I will guess if you use any of the other straps, your data would be closer to the watch 10. Now one thing you did not mention about the "Milanese strap" for those of us with hairy wrists, this is torture.....it will rip out hairs continuously.....to the point that I had to shave my wrist area!!! to avoid hair pulling and improve reading of the sensors......
