How the Tank Must Extra-Large (automatic) wears

Its lugs reach 10 mm past the 31 mm case, more than the 7 mm typical across the almanac, so it wears larger than its diameter suggests.

On our fit model it sits best on wrists from 5.75" to 6.75" (14.6–17.1 cm); below 5.75" the lugs start to reach the edge of the wrist.

At 8.4 mm thick it is slimmer than 83% of the 75 other dress watches we've measured, so it slides under a cuff more easily than most.

Will the Tank Must Extra-Large (automatic) fit your wrist?

With a 41 mm lug-to-lug, here is how it wears across common wrist sizes. We estimate the flat top of each wrist from its circumference; measure yours for a closer answer in the fit finder.
