Strap for Divers Sixty-Five 39 Stainless Steel / Brown / Bracelet

The lug width (or lug size) of the Oris Divers 65 01 733 7795 4051-Set is 19mm. This measurement represents the distance between the two spring bars (pins) that attach the strap to the watch lugs. Verifying this dimension is essential before purchasing any aftermarket strap to ensure perfect compatibility and avoid excessive play or structural stress.

The choice depends on intended use and personal aesthetics. For formal contexts, a strap in vegetable-tanned leather or genuine alligator offers sustained elegance. For sports or diving applications, NATO straps in woven nylon provide practicality and moisture resistance. Natural rubber straps represent the technical solution if the Divers 65 is used for professional diving. Shell cordovan offers an intermediate choice for those seeking refined aesthetics and material longevity.

Strap replacement requires a specific tool: a spring bar tool or pin removal device. Procedure: place the Divers 65 on a soft surface (microfibre cloth), locate the pin between the lug and strap, insert the curved tip of the spring bar tool under the pin and press gently to release the internal spring mechanism, carefully remove the old strap, insert the pin into the new strap ensuring perfect alignment, and press until you hear the locking click. We recommend practising on a non-critical strap before operating on the Divers 65 itself.

Yes, provided they strictly adhere to the 19mm lug width specification. Aftermarket straps manufactured to correct construction standards are fully compatible and do not compromise the structural integrity of the watch. However, it is essential to rely on specialised suppliers that guarantee precise dimensional tolerances. Milanostraps.it offers 19mm straps specifically tested for this model, available in various materials and finishes.

Lifespan depends on material, usage, and maintenance. Vegetable-tanned leather typically lasts 3-5 years with regular wear, improving aesthetically over time through natural patina development. Shell cordovan easily reaches 7-10 years or beyond, as the material hardens and polishes with ageing. Genuine alligator offers durability comparable to shell cordovan. To extend longevity, expose the strap to air periodically, avoid stagnant moisture, and occasionally apply plant-based leather oils. Nylon NATO straps exceed 10 years durability under normal conditions, whilst natural rubber resists 5-8 years before replacement becomes advisable.
