Strap for Divers Sixty-Five 40 Social Club Edition / United Arab Emirates

The lug width of the Divers 65 is precisely 20mm. This measurement represents the distance between the two spring bar pins on each side of the case. To verify strap compatibility, measure the distance between these pins using a digital calliper—the value must be exactly 20mm, with a maximum tolerance of ±0.2mm.

The Divers 65 pairs exceptionally well with alligator or shell cordovan straps for formal contexts, due to the patina they develop over time in contrast with the brushed case. For sporting or aquatic use, NATO straps in twisted cotton or vulcanised FKM rubber are ideal as they resist moisture and saltwater corrosion. Vegetable-tanned calf leather represents the versatile compromise between formal aesthetics and practical maintenance.

Strap replacement is performed using a Spring Bar Tool, a small metal lever that compresses the baionette springs on the sides of the case. Position the tool under the spring, gently press to release the pin, then extract the spent strap. Insert the new strap by aligning the pins with the seats, release the lever, and verify that the strap is firmly locked. The operation is entirely reversible if executed with care and proper tools.

Yes, completely. Aftermarket straps must comply with the 20mm lug width specification and standard pin geometry. Atelier Casati Milano verifies every strap using digital callippers prior to dispatch to guarantee absolute compatibility. Artisanal-quality straps frequently exceed OEM specifications in terms of finishing and stitch durability.

A high-quality leather strap with vegetable tanning and artisanal stitching typically resists 3-5 years of daily wear. Longevity depends on environmental factors: sun exposure, humidity, wearing frequency, and cleaning method. Leather ages elegantly, developing patina, so deterioration is not linear—often the strap remains aesthetically and functionally sound beyond 5 years, bearing visible character marks. Vulcanised rubber has superior longevity (7-10 years) as it is not subject to biological oxidation processes.
