C65 Aquitaine Automatic

Its lugs add 5.7 mm to the 41 mm case, close to the 7 mm typical across the almanac, so its diameter is a fair guide to how it wears.

On our fit model it sits best on wrists from 6.5" to 7.75" (16.5–19.7 cm); below 6.5" the lugs start to reach the edge of the wrist.

At 12.4 mm thick it is slimmer than 73% of the 124 other dive watches we've measured, so it slides under a cuff more easily than most.
