A watch that belongs on you.

On a 6.5-inch (165 mm) wrist, the top wrist width is roughly 52.4 mm: watches with a 36 mm to 40 mm case and 43 mm to 47.5 mm lug-to-lug deliver a balanced 75%–86% coverage. On a 7-inch (178 mm) wrist (~56.5 mm top span), 38 mm to 42 mm cases with up to 50 mm lug-to-lug fit comfortably without overhang.

Collectors and watchmakers aim for the effective lug-to-lug length to cover between 65% and 85% of the flat top width of your wrist. Above 90%, the strap drops almost vertically and the lugs can overhang the edges of your wrist.

Dial opening (bezel width), dial colour, and lug length heavily influence visual scale. A white-dial 36 mm Bauhaus watch with an ultra-thin bezel and long straight lugs appears larger on the wrist than a 38 mm dive watch with a thick dark rotating bezel and compact lugs.

The golden ratio for classic watch design is a lug width equal to 50% of the case diameter (e.g., 20 mm strap on a 40 mm case, or 19 mm/20 mm on a 38 mm case). A wider 22 mm strap gives a muscular tool-watch stance, while a tapering 20-to-16 mm bracelet refines the silhouette.

Wrap a flexible tape measure or paper strip just above your wrist bone (ulnar styloid) where your watch naturally rests, then read the circumference in millimetres on our calibrated strip ruler.
