How it sits on your wrist

Set your wrist circumference to compare the 36 mm case with a schematic wrist. The ellipse estimates wrist width and shape. It cannot predict your fit.

This wrist model is about 56 mm across. The case spans 64% of that estimated width. The lug span ends 4.7 mm inside each model edge.

Wrap a strip of paper round your wrist just below the bone, mark where it meets and measure it.
