Strap for Oris Divers 65 01 733 7707 4355

The lug width of the Oris Divers 65 01 733 7707 4355 is 20mm. This measurement corresponds to the distance between the two metal lugs (spring bar attachment points) on the case shoulder. To measure correctly, use a calliper positioned on the inner side of the lugs: your strap must present the same width in the accommodation zone.

For the bronze Divers 65, we recommend natural alligator with fine grain or vegetable-tanned leather. Alligator provides elegance without betraying the tool-watch spirit, whilst vegetable-tanned leather ages with dignity, acquiring honey or hazelnut tones over time. Alternatively, vulcanised rubber maintains the original utilitarian character with practical moisture resistance in aquatic environments.

Strap replacement occurs through removal of the spring bars (steel rods that secure the strap in the case lugs). Using a spring bar tool, apply gentle upward pressure to one of the two spring bars to release the old strap. Insert the new 20mm strap into the same lugs and verify that the spring bars lock correctly on both sides.

Yes, the Oris Divers 65 01 733 7707 4355 is fully compatible with aftermarket 20mm lug width straps. It is essential to choose straps from reputable suppliers that respect construction tolerances: minimal variations in width can generate play or poor adhesion. We recommend always verifying technical specifications before purchase.

The lifespan of a leather strap depends on usage and storage. With ordinary care (drying after moisture exposure, periodic rest), a quality alligator or vegetable-tanned leather strap can last 3–5 years. Vegetable-tanned leather, though less resistant to constant moisture, develops a fascinating patina over time. Vulcanised rubber straps, conversely, maintain structural integrity for 10+ years if stored away from direct UV light.
