Best rectangular watches for a 6.5-inch wrist

A 6.5" wrist is about 51.2 mm across, so a rectangular watch fits it best up to 47.2 mm lug-to-lug. 19 we've measured do, from the Longines DolceVita 28.20 x 47 Automatic at 47 mm down to the Nomos Glashütte Tetra 27 at 38.5 mm. Largest first, so you see the most wrist presence that still fits.
