Choosing Based on Wrist Size
Wrist circumference helps determine which size looks proportional.

- Over 180mm: 44mm recommended for balance and readability
Measure your wrist by wrapping a flexible measuring tape around your wrist bone where you wear a watch.

The 44mm model provides tangible advantages in daily use.
- Battery: 44% more capacity (410mAh vs 284mAh), lasting 10+ hours longer per charge
- Display: 14% larger screen (1.36" vs 1.19"), making notifications easier to read
