Strap for Oris Divers 65 01 733 7707 4357

The Oris Divers 65 01 733 7707 4357 is fitted with a 20mm lug width. This dimension is fixed by the 40mm case diameter and the attachment lugs (also called ears). Any third-party strap must respect this exact specification to ensure correct fitment to the springbars without lateral play or misalignment.

For the bronze Divers 65, we recommend vegetable-tanned leather in chocolate brown or tobacco shades, which complements the natural patina development of the case. Alternatively, NATO straps in navy blue or powder blue create an authentic nautical aesthetic. For genuine diving use and maximum durability, esterified rubber offers certified water resistance and zero moisture absorption.

Use a dedicated spring bar removal tool. Place the watch on a stable surface, position the tool tip into the small lateral hole of the spring bar, and push gently upward to release the internal spring tension. Extract the bar from one end only. Repeat for the second bar. Insert the new strap by threading one bar first, then press down gently until you hear the click of engagement. The process takes less than 60 seconds with practice.

Yes, absolutely. The 20mm lug width is a standard specification, and numerous artisanal straps in leather, alligator, shell cordovan and technical elastomers are fully compatible. Ensure that the replacement strap uses springbars of identical length to the original Oris (typically 18–20mm for a 40mm case) to guarantee perfect alignment to the lugs.

A vegetable-tanned leather strap lasts typically 3–5 years with daily wear and regular maintenance (monthly cleaning, twice-yearly conditioning). Vegetable tanning develops a desirable patina over time but requires protection from excessive humidity exposure. A NATO strap typically offers superior durability (5–7 years) due to its non-porous construction. Esterified rubber can exceed 10 years if stored away from prolonged direct UV exposure.
