Optical Heart Rate Monitor Accuracy Decrease Over Time

This watch has some many useful function including calling for help if you fall, heart rate monitor and other health app. I feel like Dick Tracy when I speak into my watch using the intercom or answering a phone call.

[This review was collected as part of a promotion.] The refresh rate and accuracy of this monitor is top notch. I absolutely love it. My only issue that I have is that every so often, it doesn't turn on and I have to unplug the cable from the power block and back in again. The power block is typically super hot when this happens. Not sure why it over heats like that as most of the time I find this happening is when I haven't been using the PC and the monitor was off for hours. Doesn't make sense to me but take that out of the equation and it's AMAZING!

I use it on my 24-105mm lens. I did not detect any decrease in optical quality.

Very well made design. Does not decrease optical performance of my Sony 24-105 f/4 lens. Resists dust, fingerprints, etc.

This is the third Apple watch I've owned. It seems that this watch works a little faster than the others. I use it as much for health issues. The Heart Rate monitor picks up the same as my belt. This is an improvement over the past watches. The Blood O2 is good, particularly now with Covid as lung function is an indication of the virus. All in all it's a worthwhile purchase.

This watch is absolutely perfect for my husband and I. We aren't sports fanatics but need to keep track of heart rate. We walk, ride bicycle, and treadmill. This watch tracks it all. Best of all, we only have to charge once every 3-4 weeks. Just wish I could get another one in the white rock color.

This paper holds up very well over time and I and get good color accuracy relative to my calibrated monitor. The Ultra Premium Luster produces a bit better color but for many applications the Matte Heavyweight is plenty good and is more economical.

Incredible color accuracy and HDR; the local dimming is a wonder and the 240 Hz refresh rate is sure to add to the experience. At the moment this is my favourite monitor
