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.
17.0 cm6.7 in around
This wrist model is about 56 mm across. The case spans 64% of that estimated width. The lug span ends 4.9 mm inside each model edge. Thickness is unknown, so no case height is drawn.
Wrap a strip of paper round your wrist just below the bone, mark where it meets and measure it.
