Strap for Divers Sixty-Five 40 Social Club Edition / Kuala Lumpur

The lug width of the Oris Divers 65 01 733 7707 4051 OSC-KUL-Set is 20 millimetres. This measurement represents the distance between the inner points of the two lugs of the case: to verify it correctly, use a digital calliper by positioning the tip on the inner shoulder of one lug and measuring to the inner shoulder of the other lug. 20mm straps will ensure precise fitting without angular play.

For the Divers 65 01 733 7707 4051 OSC-KUL-Set, we recommend first and foremost a vegetable-tanned leather strap: Tuscan leather ages naturally developing rich patina and pronounced texture over time. For frequent aquatic use, a natural or synthetic rubber strap offers superior resistance to chlorine and marine salts. Black opaque alligator provides formality without excess. NATO straps ensure maximum versatility and safety during diving activities.

Strap changing requires a specific tool: the spring bar tool, a small steel lever with two opposing notches. Position one notch under the case lug, pushing slightly upward to release the internal spring that secures the spring bar to the strap. Repeat the operation on the opposite lug. Extract the old strap. For mounting the new one, align the strap holes with the spring bar pins and press until you hear a slight click confirming the lock. Verify that the strap adheres perfectly on both sides without any play.

The original strap of the Divers 65 01 733 7707 4051 OSC-KUL-Set has a width of 20 millimetres. It is compatible only with watches that present the same lug width. Before purchasing an aftermarket strap, always measure your watch's lug width: if it is 20mm, any strap of that width will be compatible; if your watch has a different lug width, the strap will not fit correctly.

The lifespan of a vegetable-tanned leather strap depends on water exposure, frequency of use and maintenance care. With moderate daily non-aquatic use, the average resistance is four years. If the Divers 65 is worn frequently in water, the strap requires rapid drying post-immersion and annual protective treatment with natural waxes. Rubber straps, by contrast, offer superior resistance in humid and saline environments, with a lifespan of six to seven years. Alligator ages elegantly without structural compromise for eight to ten years of moderate use.
