Strap for Divers Sixty-Five Collective C.04

The lug width (distance between spring bars) of the Oris Divers 65 01 400 7772 4316-Set is 20mm. This measurement refers to the space between the two pins that connect the strap to the case lugs. To verify this dimension, remove the current strap and measure the distance between the two lateral holes using a digital calliper. Precision is essential to ensure correct mounting of a replacement strap.

The ideal strap type depends on intended usage. For diving: FKM rubber or marine-grade silicone provides grip on wet wrists and rapid drying. For daily elegant wear: vegetable-tanned calf or alligator creates chromatic harmony with the bronze patina. For tactical versatility: NATO straps in Cordura canvas offer durability and ease of replacement. The bronze-stainless steel case pairs naturally with dark tones (black, navy blue, brown) that enhance legibility and sophistication.

To change the strap you will need: 1) A spring bar removal tool or a thin flathead screwdriver. 2) Locate the metal spring inside the case lug. 3) Insert the tool into the release hole and gently press to compress the spring. 4) Extract the pin. Repeat for both sides. To mount the new strap, insert the pin through the strap holes while aligning it with the case lugs, then compress the spring again until the pin clicks into position. Verify that the strap is secure before wearing the watch.

Yes, absolutely. Any strap with a 20mm lug width is compatible with the Divers 65 01 400 7772 4316-Set. Quality aftermarket straps allow you to customise the watch for different contexts: alligator for formal occasions, vegetable-tanned calf for aesthetic evolution parallel to the bronze patina, NATO for tactical versatility, and marine rubber for actual diving. Always verify that the pin diameter matches (typically 1.6mm) and that the ends are specifically shaped for Oris lugs.

Leather strap longevity depends on leather quality and usage frequency. Quality vegetable-tanned calf, worn daily, maintains acceptable functionality and aesthetic appearance for 18–30 months. Alligator, a harder and more resistant material, can exceed 3–4 years of service. Leather is vulnerable to prolonged immersion in salt water: if you use the Divers 65 in marine environments, alternate leather straps with marine rubber to extend longevity. Factors such as personal perspiration, ambient humidity and maintenance significantly influence durability. Regular maintenance—gentle cleaning and application of natural protective products—can increase strap lifespan by up to 50%.
