AAA batteries are a pretty good match!
- All models of the watch are exactly the same thickness as a triple-a battery.
- Three AAA batteries together are a little longer and a little thinner than the bigger 42mm Apple Watch.
- Those same three batteries are about the same weight as the watch part of the Sport model, 33 vs 30 grams (for all, bands add more.)
- The steel model weighs in the middle between 4 and 5 AAA batteries.
- The gold model weighs the same as 6 AAA batteries.
