Strap for Divers Sixty-Five 40 Social Club Edition / London

The lug width is 20 millimetres. This measurement is taken by positioning a digital calliper between the two metal lugs that protrude from the case. With this measurement, you can verify the compatibility of any third-party strap and ensure correct installation of the spring bars.

It depends on the intended use. For formal daily wear, we recommend an alligator strap dyed in dark blue or cognac brown, which enhances the sunburst dial. For sporting activities and use in humid environments, a grey or navy blue NATO fabric offers robustness without compromise. For diving and water-based activities, a heat-vulcanised FKM rubber guarantees grip even on a wet wrist. For elegant occasions, a burgundy shell cordovan conveys understated luxury.

The lugs are threaded to accommodate solid spring bars. Use a dedicated spring bar tool to carefully extract the spring bars from the case. Insert the new strap by aligning the holes with the lugs, then re-insert the spring bars until they click into place. Verify that the spring is firmly secured before wearing the watch.

All straps with a 20mm lug width are compatible. Milanostraps.it offers a complete selection of 20mm straps in alligator, vegetable-tanned leather, NATO, FKM rubber and shell cordovan. Each strap is handcrafted and tested to guarantee smooth installation and durable mechanical retention.

A quality handcrafted alligator strap, if not regularly exposed to water, maintains structural integrity for 3-5 years of daily wear. Frequent exposure to moisture and chlorine reduces this lifespan. It is advisable to alternate leather straps with a NATO fabric or rubber strap when engaging in water-based activities, and to store leather straps in a dry location. The patina developed over time is considered a merit, not a defect.
