Best sport watches for a 6.5-inch wrist

A 6.5" wrist is about 51.2 mm across, so a sport watch fits it best up to 47.2 mm lug-to-lug. 19 we've measured do, from the Oris ProPilot X Calibre 400 at 47 mm down to the Tissot PR516 Powermatic 80 38mm at 44 mm. Largest first, so you see the most wrist presence that still fits.
