Strap for Divers Sixty-Five Carl Bronze / Blue / Brashear Limited Edition

The lug width of the Oris Divers 65 01 733 7720 3185-Set LS is 20 millimetres. This measurement represents the distance between the two horizontal pins (spring bars) that attach the strap to the case. It is essential to verify this measurement before purchasing an aftermarket strap to ensure compatibility and secure assembly.

The ideal strap depends on intended use. For everyday elegance, we recommend vegetable-tanned calf leather or shell cordovan in cognac tones, which pairs beautifully with the patina the bronze case develops over time. For sports use and diving, medical-grade FKM rubber is unmatched: it resists saltwater, does not absorb moisture, and maintains elasticity even in cold environments. Organic cotton NATO straps offer versatility and rapid replacement capability when travelling.

Strap replacement is performed by removing the spring bars—the horizontal pins anchoring it to the case. A dedicated spring bar removal tool is available at low cost, or you may entrust the task to a professional watchmaker. With the Oris Divers 65, we recommend fully screwing down the crown before any manipulation to protect water resistance. Always ensure the spring bars are inserted symmetrically into the lugs of the case.

Yes, thanks to the standard 20 millimetre lug width, the strap from the Divers 65 01 733 7720 3185-Set LS is compatible with any watch fitted with 20mm lugs. However, we recommend always verifying case thickness and proportions, as a strap may appear visually disharmonious if paired with a case of very different shape or dimensions. Technical compatibility does not guarantee aesthetic harmony.

The lifespan of a leather strap depends on the quality of tanning, exposure to saltwater, and frequency of use. High-quality leather with vegetable tanning, worn primarily in urban settings, can remain in excellent condition for 4–6 years. However, if regularly exposed to diving or saltwater, durability reduces to 1–2 years. In such cases, we recommend opting for interchangeable FKM rubber straps, or maintaining multiple leather straps to rotate, allowing the leather to dry completely between uses.
