Strap for Divers Sixty-Five 40 Movember Edition

The lug width is precisely 20 millimetres. Measure this distance with a digital calliper or ruler between the inner edges of the lugs that hold the strap. Measuring externally will yield 22-23mm and lead to incompatible strap orders—internal measurement is mandatory.

Selection depends on intended use: for frequent diving, NATO in aramidic or FKM rubber dries quickly and maintains dimensional stability. For daily urban wear, Italian vegetable-tanned calf or caramel alligatore develop rich patina over time and harmonise with the satin-finished case. All our <a href="https://milanostraps.it/collections/cinturini-orologi-per-misura-ansa-20mm">20mm straps</a> are compatible.

Remove the original strap by depressing the lug pins towards the centre with a spring bar tool or dedicated strap remover. Insert the new strap by aligning its holes with the lugs, then depress the pin from the opposite side until it clicks into place. No specialised tools required; deliberate, controlled movements suffice.

Yes—any strap with 20mm lug width is compatible. We recommend straps manufactured from dimensionally stable materials: leather minimum 1.4mm thickness, NATO in certified aramidic, or FKM rubber to specification. Avoid undersized straps prone to loosening during wear.

A quality leather strap (Italian vegetable-tanned calf or alligator) lasts 3–5 years with daily wear, extending to 10 years with occasional use. Moisture accelerates degradation; if you frequently use your Divers 65 in water, NATO or rubber will offer superior longevity. Patina development continues beyond five years even after the strap has been retired.
