Strap for Divers Sixty-Five 40 Stainless Steel / Blue / Rubber

The lug width (distance between the lugs) of the Oris Divers 65 01 733 7707 4035-07 4 20 18 is 20mm. This standard measurement for 40mm cases ensures full compatibility with all 20mm aftermarket straps available on MilanoStraps.

Selection depends on usage: for regular diving, an FKM rubber strap offers salt-water resistance and washability. For daily elegance, vegetable-tanned alligator leather develops natural patina over time. NATO in Cordura tarpaulin combines sporty versatility with casual transition. For maximum formality, dark calf leather with stainless steel deployante buckle.

Remove the watch from your wrist. Using a spring-bar tool or small screwdriver, gently press the terminals of the pins fastening the bracelet to the case lugs (at 12 and 6 o'clock). The sliding pins will exit outward. Insert new pins into the replacement strap, aligning them with the lugs, then press until you hear a click. Verify the strap is firmly secured before wearing.

Any strap with a 20mm lug width is compatible. MilanoStraps offers a curated selection of artisan straps in leather (alligator, shell cordovan, vegetable calf), NATO in certified Cordura canvas, and medical-grade FKM rubber. All models feature quick-release bars or are customizable with hand-stitched lugs.

A high-quality artisan leather strap, under normal use (not frequent diving), lasts 5–7 years maintaining structural integrity. Regular exposure to fresh water (shower, rain) does not compromise properly vegetable-tanned leather, but lifespan shortens if exposed to pool chlorine or sea salt without rinsing. FKM rubber, being fully waterproof, has superior durability (10+ years) in severe wet environments.
