We have not verified this watch’s lug-to-lug yet, so we can’t draw it on a wrist. Case diameter alone is a poor guide to fit.

How the Ballade 39mm COSC wears

At 11 mm thick it is thicker than 57% of the 118 other dress watches we've measured, so expect it to sit tall on the wrist.

Its 20 mm lug width is one of the most common strap sizes; 186 other watches here share it, so aftermarket straps are easy to find.
