Strap for Oris ProDiver 01 667 7645 7284

The lug width of the Oris ProDiver 01 667 7645 7284 is 26mm. This measurement is precise and invariable: any 26mm-compatible strap from another watch will fit correctly. Measurement should be performed with a digital calliper, measuring the distance between the inside of both lugs (the pins connecting the strap to the case).

For a technical diver like the ProDiver, the best strap depends on intended usage. For prolonged professional diving, a high-density rubber strap offers total water impermeability and zero water absorption. For mixed use (diving and semi-formal), an alligator strap with vegetable tanning ensures durability, discreet aesthetics and the ability to develop patina over time. For tactical versatility, a Cordura NATO is practical, easy to clean and suitable for marine environments.

Changing the ProDiver's strap requires a dedicated spring bar tool: position the tool's tip in the lateral groove of the lug, apply gentle pressure to compress the internal spring of the bar and slide the lug out of the case housing. Reverse the procedure to insert the new 26mm strap, ensuring the bars are fully seated in the case slots.

Yes, any strap with 26mm-compatible lugs (i.e. with external dimensions correct to fit into the case slots) can be mounted on the ProDiver. Artisanal leather, technical rubber or high-quality textile straps often offer superior comfort, durability and aesthetics compared to original Oris options, allowing customisation of your watch's mission.

Durability depends on leather type and maintenance. An alligator strap with vegetable tanning, if air-dried regularly after diving and conditioned every 3-4 months, can last 3-5 years in alternating diving use. A calf leather strap lasts 2-3 years under similar conditions. Rubber and technical textile straps have indefinite lifespan if cleaned and dried correctly, though finishes (stitching, buckle) may wear after 5-7 years of intensive use.
