How the Astra wears
Its lugs add 8 mm to the 36 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 6.25" to 7.25" (15.9–18.4 cm); below 6.25" the lugs start to reach the edge of the wrist.
At 10.4 mm thick it is slimmer than 57% of the 56 other dress 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; 104 other watches here share it, so aftermarket straps are easy to find.
Will the Astra fit your wrist?
With a 44 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 | Wears small |
| 8" | 63 mm | Wears small |
