Best rectangular watches for a 6.75-inch wrist

A 6.75" wrist is about 53.1 mm across, so a rectangular watch fits it best up to 49.1 mm lug-to-lug. 20 we've measured do, from the Cartier Santos de Cartier Large at 47.5 mm down to the Söner Nostalgia Caesar at 40 mm. Largest first, so you see the most wrist presence that still fits.
