Strap for Divers Sixty-Five 38 Cotton Candy Stainless Steel / Pink / Perlon

The Oris Divers 65 features a lug width of 19 millimetres. This dimension is the historical standard for professional diving instruments and ensures balanced visual proportions relative to the 38mm case. To verify strap compatibility, measure the internal distance between the two lug pins on the case: it must be exactly 19mm.

The choice depends on intended use. For formal and daily wear, vegetable-tanned alligator offers elegance and natural patina development. For sport and water activities, FKM rubber guarantees waterproofing and durability. NATO fabric represents the versatile compromise, transforming the watch into a pure, austere instrument. Vegetable-tanned calf leather is the intermediate solution, combining refined aesthetics with everyday robustness.

Strap change is a straightforward operation. Obtain a spring bar remover tool. Position the watch case-up, then insert the tool tip under the lug pin and gently press to release the internal spring. Remove the old strap and insert the new one by aligning the holes with the case lugs, pressing until the spring clicks into position. Repeat on the other side.

Yes, any strap with a 19mm lug width is compatible with the Oris Divers 65 01 733 7771 4058-07 3 19 04S. However, verify that the material thickness is not excessive and that strap height does not interfere with the crown at three o'clock. Artisanal straps offer greater customisation freedom compared to original models, allowing choices of materials (alligator, shell cordovan, vegetable-tanned calf) and alternative colours.

A high-quality vegetable-tanned calf strap lasts approximately 5–8 years with routine maintenance. The leather evolves, developing a characteristic patina that increases aesthetics over time. Alligator, being harder and more compact, frequently exceeds 10 years of service. FKM rubber has a similar lifespan to calf but shows less aesthetic evolution. Avoid prolonged direct sunlight and stagnant humidity to preserve the fibrous structure.
