How the Prospex 1965 Diver's Modern Re-interpretation wears

Its lugs add 7.1 mm to the 40.5 mm case, close to the 7.1 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" (17.1–20.3 cm); below 6.75" the lugs start to reach the edge of the wrist.

At 13.2 mm thick it is thicker than 63% of the 79 other dive watches we've measured, so expect it to sit tall on the wrist.

Will the Prospex 1965 Diver's Modern Re-interpretation fit your wrist?

With a 47.6 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.
