Series 8 890 Mechanical

Its lugs add 8.1 mm to the 42.6 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 7" to 8.5" (17.8–21.6 cm); below 7" the lugs start to reach the edge of the wrist.

At 11.7 mm thick it is slimmer than 70% of the 82 other sport watches we've measured, so it slides under a cuff more easily than most.
