Strap for Oris Divers 65 01 733 7720 4034

The lug width is 21mm. This is the space between the lugs where the strap attaches. You can verify it by measuring directly on the case with a digital calliper or ruler, ensuring the spacing is precisely 21mm wide.

It depends on use case: for vintage elegance, a brown or black leather strap with vegetable tanning and natural patina. For active diving, a 21mm NATO or FKM rubber strap ensures resistance to saltwater corrosion. Structured alligator leather offers the compromise between refinement and sportiness.

The Divers 65 uses standard spring bars. Locate the small grooves at the strap ends, insert the removal tool into the slot and gently push the spring bar toward the centre until it disengages. Remove the old strap and insert the new one, aligning the holes, then reinsert the spring bar until it clicks into position.

Yes, provided it is specifically designed for 21mm lug width. Always verify the declared width from the manufacturer. Leather, alligator, NATO, and rubber straps from established brands are fully compatible with the Divers 65's standard spring bars, allowing complete customisation.

A quality vegetable-tanned leather strap, with proper maintenance (drying after accidental water contact, conditioning every six months), lasts 3–5 years of regular wear. Natural patina develops progressively. For frequent and prolonged marine use, rubber or NATO straps offer superior durability.
