How it sits on your wrist

Set your wrist circumference to compare the 38 mm case with a schematic wrist. The ellipse estimates wrist width and shape. It cannot predict your fit.

17.0 cm6.7 in around

This wrist model is about 56 mm across. The case spans 68% of that estimated width. Lug to lug is unknown, so no lug extent is drawn.

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