Strap for Divers Sixty-Five 40 Stainless Steel / Bronze / Black / Rubber

The Oris Divers 65 01 733 7707 4354-07 4 20 18 features a lug width of 20mm. This dimension is standard for 40mm diving watches and is compatible with all straps designed for this measurement, from leather models to tactical NATO configurations.

The ideal strap depends on intended use: for diving, a cordura NATO or FKM rubber ensures grip and reliability; for daily wear, vegetable-tanned leather develops patina harmonising with the case's bronze aging; for formal elegance, alligator in brown tones offers sophistication without compromising the design's sporting character.

Remove the strap using a spring bar tool to gently extract the pins from the case's lug holes. Once freed on both sides, align the new strap with the lugs and reinsert the pins until they click into place. For leather straps, soft quick-release spring bars are recommended to avoid repeated stress on the fibres.

Yes, quality aftermarket straps are fully compatible provided they have a 20mm lug width. Many owners prefer custom artisanal straps to personalise design and materials: vegetable-tanned leather, shell cordovan, butyl rubber, or high-grade NATO allow you to customise the watch whilst maintaining structural integrity and aesthetic value.

A quality leather strap, made from vegetable-tanned or shell cordovan leather, maintains full functionality for 3–5 years with daily wear, developing natural patina that enriches aesthetic appeal over time. Salt exposure (seawater, humidity) slightly accelerates ageing; an FKM rubber or NATO strap has a lifespan of 5–7 years without aesthetic changes, making it ideal for regular divers.
