Strap for Fifty Fathoms 500 Fathoms Cannes 2009

The lug width is 24mm. This is a specific dimension for this Fifty Fathoms family, proportioned to the 48mm case and designed for underwater wear beneath diving suits. To verify, use a digital calliper to measure the space between the case lugs where the strap attaches.

Selection depends on intended use and aesthetic preference. For diving: cold-vulcanised FKM rubber or heavy cotton NATO straps. For formal elegance: vegetable-tanned alligator in black or dark brown, or shell cordovan. All require 24mm lug width for perfect fit.

Use a dedicated spring bar tool, positioning the flat end against the lug pin and pushing inward to create clearance, then withdraw the lug from the hole. Repeat on the opposite side. Insert the new strap, aligning the holes, and reinsert the pins. Verify the strap is 24mm to prevent excessive play.

All straps featuring 24mm lug width are compatible. Milano Straps offers dedicated collections in alligator, calf leather, shell cordovan, rubber, and textile. Always verify the strap is specifically dimensioned at 24mm to ensure precise fit without tension on the lugs.

With ordinary maintenance—avoiding excessive moisture, not wearing in frequent showers, applying protective balm annually—a leather strap lasts 3–5 years. Vulcanised rubber has greater longevity (7–10 years). Casati Milano provides an 18-month warranty against manufacturing defects.
