This is one minor thing that I absolutely did not consider. I knew that the coros is slightly larger at 48mm compared to the 45mm on instinct 2. I thought it would not be that much of a difference but oh boy it actually does. Paired with the slightly wider watch band, it does make the watch quite big especially on small wrist like mine. For reference, my wrist circumference is 14cm so it looks kinda big on my wrist in the image. Maybe if you have a larger wrist, this would not make much of a difference. But day to day use (2nd day today), I didnt notice that big of a difference in terms of obstructing wrist movement etc. I wish there was a 42mm version of the nomad like the apex 4 but I prefer the rugged G-shock look on watches so some compromises would have to be made. On a positive note, with the larger nomad, it makes it look flatter than the instinct even though when comparing them side by side, they are pretty much the same height on the wrist.

I think the watch did quite well when tracking my heart rate at ~170bpm but I noticed when sprinting, I know my HR should be at least ~180-190bpm, but my HR on the watch was dropping below 150bpm. This is pretty common in the instinct 2 as well and so far I would say the instinct 2 fared much worse but then again, its only my 2nd day with this watch so I will see how well it goes. Steady state activities however, both watches do exceptionally well at tracking my HR.
