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

The lug width of this model is 20mm, defined by the distance between the integrated lugs on the case. Oris selected this dimension to maintain balanced proportions on the 40mm case, creating aesthetic harmony without visual heaviness. Any strap intended for the Divers 65 must respect this specification.

The choice depends on primary usage. For classical settings, we recommend alligator leather with vegetable tanning in medium brown: the grain texture echoes diving heritage, and patina develops over time. For operational environments, ballistic NATO or technical FKM rubber ensures robustness and easy cleaning. Vintage-tanned calf represents the compromise between elegance and daily function.

The Oris Divers 65 uses standard integrated 20mm lugs. Use a professional spring bar tool to gently extract the pin from one or both sides. Insert the new strap into the lugs, then reinsert the pin until you feel a tactile click. Do not force: the movement must be fluid to prevent case damage. If needed, consult a certified watchmaker.

Yes. Milano Straps offers a dedicated collection of 20mm straps: Italian leather with vegetable tanning, ballistic NATO, marine-grade rubber. All straps are tested for geometric compatibility and developed in collaboration with horology experts. Visit the 20mm strap section to filter by material, colour, and style.

Durability depends on tanning method and usage. Vegetable-tanned leather lasts 5–7 years in daily wear, with gradual patina development that is aesthetically desirable. Modern-tanned calf lasts 3–5 years with regular cleaning. Technical FKM rubber reaches 8–10 years if not exposed to prolonged UV radiation. The 20mm lug width of the Divers 65 does not concentrate stress on critical areas, favouring longevity.
