Strap for Oris Divers 65 01 733 7707 4386

The lug width of the Oris Divers 65 01 733 7707 4386 is 20 millimetres. This dimension refers to the distance between the two lugs (strap attachment points) on the case where the strap is inserted. To verify it, use a digital calliper, positioning the lugs between the calliper jaws: you will obtain precise confirmation of the 20mm measurement.

The best strap depends on intended use and aesthetic preference. For material and philosophical coherence, a vegetable-tanned leather strap in warm tones (brown, hazel) evolves naturally alongside the bronze case. An alligator strap offers greater formality, whilst a NATO or FKM rubber option represents sporty choices ideal for frequent diving.

Strap replacement is accomplished via the spring bars (spring-loaded pins) that connect the strap to the two case lugs. Use a dedicated tool (spring bar remover) to compress the lateral spring bars, allowing the pin to be extracted from the lug hole. Subsequently insert the new strap by engaging the spring bars into the opposite lug holes. The procedure requires approximately two minutes and does not require professional tools.

Yes, any strap equipped with a 20mm lug width is perfectly compatible with the 01 733 7707 4386. Quality aftermarket straps (leather, NATO, rubber, alligator) adapt to the original case spring bars without any modification. Compatibility depends exclusively on strap width, not on the strap brand.

A quality leather strap with vegetable tanning has an average lifespan of 3-5 years with regular use. Longevity depends on immersion frequency, sun exposure, humidity, and maintenance. Natural leather is not waterproof: following repeated immersion, the leather absorbs water and may develop stiffness or deformation. Periodic care with natural oils and rapid drying after water contact significantly extend strap lifespan.
