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

The Oris Divers 65 01 733 7707 4051 OSC-MEX-Set is equipped with a 20mm lug width. This measure is standard for professional sports instruments in this segment and allows the fitting of robust straps designed for marine and tactical environments. Lug width refers to the internal distance between the lateral pins of the case and must be verified before purchasing an aftermarket strap.

The ideal strap depends on intended use. For deep diving, we recommend natural vulcanised rubber or ballistic nylon NATO straps, materials immune to marine moisture. For elegant daily wear, vegetable-tanned alligator or slate-grey calf leather create balance between sportiness and refinement. For authentic 1960s aesthetics, a cotton-satin navy blue NATO strap directly references original military designs. Compatibility requires a 20mm lug width and the presence of a deployante clasp for secure fastening.

Strap replacement requires a spring bar tool, a specific instrument that depresses the lateral pins of the lug to release the strap from the case. Position the spring bar tool in the lateral indentations of the lug (visible on the case sides), apply gradual pressure toward the centre, and slide the strap out of the pins. Reverse the procedure to install the new strap. Important: do not use screwdrivers or improper objects, which would damage the pins. We recommend performing the operation on a soft surface (cotton cloth) to prevent accidental scratches.

All straps equipped with a 20mm lug width are compatible, provided they present sufficient total length (approximately 240-260mm for average wrists) and lug height consistent with the case profile. Handcrafted vegetable-tanned leather straps, tinted alligator leather, military NATO straps and quality natural rubber straps are perfectly integrable. We personally verify geometric compatibility: the lug must fit without lateral play, and the strap must not touch the case back.

A quality vegetable-tanned leather strap, used in a marine environment, has a lifespan of 12-24 months with regular use, considering the stress of salt humidity and ultraviolet exposure. Natural leather breathes and absorbs water, developing patina over time but gradually weakening in its fibres. To extend durability, we recommend drying the strap after each dive or prolonged contact with salt water, occasionally applying natural waxes to maintain hydration, and rotating straps to allow the leather to recover its thickness. NATO and rubber straps offer total immunity in marine environments, making them preferable for intensive professional use.
