How the Seamaster Aqua Terra 150M Shades 34 wears

Its lugs add 6.5 mm to the 34 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 5.75" to 6.75" (14.6–17.1 cm); below 5.75" the lugs start to reach the edge of the wrist.

At 11.9 mm thick it is slimmer than 63% of the 103 other sport watches we've measured, so it slides under a cuff more easily than most.

Its 16 mm lug width is less common (3 other watches here), so check strap sizes carefully.

Will the Seamaster Aqua Terra 150M Shades 34 fit your wrist?

With a 40.5 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.
