Ballon Bleu de Cartier 42

Its lugs add 7 mm to the 42 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 6.75" to 8.25" (17.1–21.0 cm); below 6.75" the lugs start to reach the edge of the wrist.

At 13 mm thick it is thicker than 92% of the 75 other dress watches we've measured, so expect it to sit tall on the wrist.
