Questions
Sizing a 7 inch (17.8 cm) wrist
What lug-to-lug fits a 7 inch wrist?
On a 7 inch (17.8 cm) wrist, a lug-to-lug between 46.7 and 56 mm (1.84 in to 2.20 in) reads as balanced, and about 49.8 mm is the sweet spot. Spans up to 59.1 mm still wear well but look large, and anything past 62.2 mm is likely to overhang.
How big a dive watch can a 7 inch wrist wear?
Up to about 59.1 mm lug-to-lug wears large but stays on the wrist; 59.1 to 62.2 mm is borderline and worth trying on first. Case diameter matters less than the lug-to-lug span, which is why a 7 inch wrist can carry a 42 mm case with short lugs more easily than a 40 mm case with long ones.
How do I measure my wrist for lug-to-lug?
Measure the flat width straight across the top of your wrist where the watch sits, not the circumference. This guide estimates flat width as 35% of circumference, so a 17.8 cm wrist is treated as 62.2 mm across; enter your own measurement in the fit calculator on any watch page for an exact result.
