How the Boulton Quartz wears

Its lugs add only 5 mm to the 27 mm case, against 7 mm typical across the almanac, so it wears smaller than its diameter suggests.

At 32 mm lug-to-lug it wears small on every common wrist size, which suits smaller wrists and a vintage look.

At 7.8 mm thick it is thicker than 53% of the 47 other rectangular watches we've measured, so expect it to sit tall on the wrist.

Its 18 mm lug width is one of the most common strap sizes; 24 other watches here share it, so aftermarket straps are easy to find.

Will the Boulton Quartz fit your wrist?

With a 32 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.
