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 Master Control Chronometre Date wears

At 8.4 mm thick it is slimmer than 86% of the 21 other integrated bracelet watches we've measured, so it slides under a cuff more easily than most.
