Strap for Oris Divers 65 01 733 7707 4055

The Oris Divers 65 01 733 7707 4055 features a lug width of 20mm. This measurement is determined by the distance between the two lugs (lateral case attachments) and is the standard for mid-sized diving watches. To verify the correct measurement, position a digital calliper or ruler perpendicular to the case plane, between the lugs, excluding any case curvature.

For the 01 733 7707 4055 model we recommend three directions: vegetable-tanned alligator for formal elegance and natural patina development; shell cordovan if you desire distinctive grain and marked aesthetic personality; NATO in fabric or bitension rubber to emphasise the watch's diving vocation. Your choice depends on intended use and wearing context. All materials must be 20mm.

The strap is replaced by removing the spring bars that connect the strap to the case lugs. Use a dedicated spring bar remover tool to gently compress the bar from the underside, allowing it to pop out of the lug slot. Once both bars are free, remove the old strap and insert the new one (ensuring it is 20mm), reinserting the bars into the opposite lugs. Verify that they click correctly before wearing the watch.

Yes, any high-quality aftermarket strap with a 20mm lug width is compatible with the Oris Divers 65 01 733 7707 4055. The important thing is to verify total length (overlap on the case) and exact width. Bespoke artisanal straps guarantee perfect fit and allow you to personalise colour, material and buckle according to your aesthetic and usage preferences.

The lifespan of a leather strap varies based on material, frequency of use and exposure to external agents (chlorine, salt water, sweat, sunlight). A high-quality artisanal alligator or shell cordovan strap lasts approximately 4-7 years with regular use, developing a desirable patina. Leather experiences structural fatigue around flexion areas and in buckle holes. To extend lifespan, dry the strap after water exposure and store away from direct heat sources. A rubber strap has comparable longevity but degrades differently, stiffening over time.
