Strap for Oris Divers 65 01 400 7772 4217

The lug width of the Oris Divers 65 01 400 7772 4217 is 20mm. This measurement represents the distance between the two lateral lugs (pins) of the case. To verify it, use a digital calliper positioned from the centre of one lug to the centre of the other. The 20mm width is the defining standard for this specific model, ensuring harmonious proportions with the 40mm case diameter.

The best strap depends on usage and personal preference. For authentic vintage aesthetics, we recommend textured alligator in navy blue or bottle green, or vegetable-tanned calf leather that develops a natural grey-brown patina over time. For operational authenticity, a grey graphite or black NATO strap in cordura restores the integrity of the 1960s originals. For versatility and practicality, a vulcanised FKM rubber strap is waterproof, UV-resistant, and maintenance-free. Your choice should reflect the narrative you wish to create for your diving tool.

Changing the strap on the Oris Divers 65 is a straightforward operation. Use a spring bar remover or a blunt metal pin to gently push the elastic pin inward towards the case, creating space to extract the strap end. Repeat on the other side. Insert the pins of the new strap into the appropriate holes in the case, ensuring the elastic pin clicks firmly into position. Never force the pins as this may damage the case.

Yes, you can fit quality aftermarket straps to the Oris Divers 65 01 400 7772 4217 case, provided they are designed for the 20mm lug width. We recommend straps in alligator, vegetable-tanned calf, NATO cordura, or vulcanised rubber. Ensure the strap is fitted with robust elastic pins compatible with the case lugs. A quality artisanal strap not only lends personality to your watch but improves comfort and durability compared to standard factory alternatives.

A quality leather strap, worn regularly on a diving watch, has an average lifespan of 3-5 years, provided it is cared for properly. Frequent exposure to salt water, chlorine, and UV rays accelerates leather ageing. To extend strap life, dry it thoroughly after every water contact, avoid prolonged direct sunlight, and periodically apply a specific conditioner for immersed leathers. A vegetable-tanned calf strap becomes more beautiful over time, developing a unique patina. For intensive aquatic environments, choose vulcanised rubber or NATO, which offer virtually unlimited durability.
