Size and Fit
Measurements that decide how a watch sits on the wrist, plus endurance figures like power reserve.
- Lug-to-Lug
- Lug-to-lug is the vertical distance from the tip of the top lug to the tip of the bottom lug. It, not the case diameter, decides whether a watch will actually fit your wrist.
- Power Reserve
- Power reserve is how long a fully wound mechanical watch keeps running off the wrist. On most automatics it is around 40 hours; some models reach 70 hours and beyond.
