How the The Twelve 40mm wears
Its lugs add only 4.5 mm to the 40 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 6.25" to 7.5" (15.9–19.1 cm); below 6.25" the lugs start to reach the edge of the wrist.
At 9.9 mm thick it is slimmer than 62% of the 21 other integrated bracelet watches we've measured, so it slides under a cuff more easily than most.
Will the The Twelve 40mm fit your wrist?
With a 44.5 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.
| Wrist | Flat width (est.) | Fit |
|---|---|---|
| 6" | 47.2 mm | Snug, lugs near the edge |
| 6.5" | 51.2 mm | Ideal fit |
| 7" | 55.1 mm | Ideal fit |
| 7.5" | 59.1 mm | Ideal fit |
| 8" | 63 mm | Wears small |
