Already did, the other day.
Anybody upgrading from U2 to U3? I'm checking the comparison here and really no difference between U2 and U3 in term of software...
https://www.apple.com/watch/compare/?modelL...3,watch-ultra-2Hardware wise, some differences:
6H extra, 15 minutes less charging time from 0% to 80%. 15 minutes for 12 hours of usage, 5 minutes for 8 hours of sleep tracking - this is actually nice.
Bigger screen, tough sapphire crystal display with titanium case.
Checked the Apple trade-in value, and it is RM 1,525 for my two-year-old U2. Battery health is now 97%, but I feel the battery life doesn't last as long once it drops below 100%.
Not sure if it is worth to to up RM 2174 for the latest U3.

bigger screen and battery with fast charging i think worth it if you have extra money.
. i'm gonna stick with my U2 at least 1-2 years more. battery still 100%
