Strap for Divers Sixty-Five 42 Stainless Steel / Green / NATO

The lug width is 21mm. This measurement is specific to this model and cannot be interchanged with 20mm or 22mm. To verify it, use a digital calliper positioned perpendicular to the two metal lugs protruding from the case.

For frequent underwater use, FKM vulcanised rubber or NATO in 450 denier cordura are recommended, both resistant to salt water. For elegant daily wear, vegetable-tanned alligator or shell cordovan develops natural patina over time and maintains elasticity in humid environments.

The strap is replaced by removing the metal pins from the case. Use a dedicated spring bar tool: insert the flat blade into the pin slot, apply downward pressure to release the internal spring, then extract the pin. Repeat on the other side. Reinsert the new pins from the 21mm strap, aligning them correctly.

Yes, provided the lug width is exactly 21mm and the thickness falls between 1.4mm and 1.6mm. The 21mm lug width straps in the milanostraps.it collection are tested and guaranteed compatible with the Oris Divers 65 ref. 01 733 7720 4057-07 5 21 25FC model.

A strap in vegetable-tanned or shell cordovan leather, if properly maintained (immediate post-dive drying, biannual conditioning with neutral creams), has an average lifespan of 3–5 years in regular use. Natural leather deteriorates if continuously exposed to salt water: for frequent diving, rubber or NATO are more durable choices. Atelier Casati Milano offers restoration and reconditioning services.
