Best dive watches for a 6.5-inch wrist

A 6.5" wrist is about 51.2 mm across, so a dive watch fits it best up to 47.2 mm lug-to-lug. 27 we've measured do, from the Baltic Aquascaphe GMT MK II at 47 mm down to the Doxa SUB 200T Professional at 41.5 mm. Largest first, so you see the most wrist presence that still fits.
