Omega x Swatch MoonSwatch Mission to Mars

Its lugs add only 5.3 mm to the 42 mm case, against 7 mm typical across the almanac, so it wears smaller than its diameter suggests.

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 13.3 mm thick it is slimmer than 63% of the 51 other chronograph watches we've measured, so it slides under a cuff more easily than most.

Its 20 mm lug width is one of the most common strap sizes; 196 other watches here share it, so aftermarket straps are easy to find.
