Strap for Oris Divers 65 01 733 7771 3154

The lug width (ansa size) of the Oris Divers 65 ref. 01 733 7771 3154 is 19mm. This dimension is determined by the geometry of the 42mm case and defines the width of the compatible strap. To measure the lug width accurately, use a digital calliper positioned between the inner edges of the lugs: the distance must be exactly 19mm. Straps with different measurements (18mm or 20mm) will not fit correctly.

For the Oris Divers 65, we recommend a Tuscan vegetable-tanned leather strap in dark brown (1.5mm thickness with brushed steel deployante), which emphasises the vintage aesthetic and natural patina of the watch. A contemporary alternative is a navy blue NATO strap, ideal if you wear the watch in humid environments or during recreational activities. If you dive regularly, opt for a black vulcanised rubber strap: it eliminates functional concerns and preserves the distinction between a precious object and a professional instrument.

The Oris Divers 65 strap is changed by extracting the spring bars using a dedicated tool or a small non-sharp blade. Position the watch on a stable, soft surface (woollen cloth), then gently press the spring bar to extract it from the lug seat. Once both spring bars are free, remove the old strap and thread the new 19mm strap by inserting the spring bars into the new holes. Ensure the strap is centred and that the spring bars are fully inserted before wearing the watch.

Yes, the Oris Divers 65 accepts any aftermarket strap with a 19mm lug width. Verify that the strap is free of defects, that the spring bars are robust, and that the construction quality is appropriate for a watch of this value. Recommended materials are alligator leather, vegetable-tanned calf, technical NATO, and vulcanised rubber. Avoid cheap polyurethane synthetic straps, which degrade rapidly under exposure to chlorine and sea salt.

A quality leather strap (Tuscan calf, alligator, shell cordovan) fitted to an Oris Divers 65 lasts an average of 3-5 years with daily use and routine maintenance. Longevity depends on weather exposure, frequency of water immersions, and care applied (periodic cleaning, rapid drying, conditioning with vegetable waxes 2-3 times yearly). A vulcanised rubber strap, conversely, remains functional for 8-10 years without structural degradation. Vegetable tanning ages more nobly than synthetic treatments, developing warmer tones and increasingly characteristic texture.
