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 World Chronograph A-T wears

At 12 mm thick it is slimmer than 87% of the 47 other chronograph watches we've measured, so it slides under a cuff more easily than most.

Its 23 mm lug width is less common (1 other watch here), so check strap sizes carefully.
