How the SUB 200T Professional wears

Its lugs add only 2.5 mm to the 39 mm case, against 7.1 mm typical across the almanac, so it wears smaller than its diameter suggests.

On our fit model it sits best on wrists from 6" to 7" (15.2–17.8 cm); below 6" the lugs start to reach the edge of the wrist.

At 10.7 mm thick it is slimmer than 100% of the 79 other dive watches we've measured, so it slides under a cuff more easily than most.

Its 18 mm lug width is one of the most common strap sizes; 12 other watches here share it, so aftermarket straps are easy to find.

Will the SUB 200T Professional fit your wrist?

With a 41.5 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.

6.5"	51.2 mm	Ideal fit
7"	55.1 mm	Ideal fit
7.5"	59.1 mm	Wears small
