Strap for Divers Sixty-Five 40 Stainless Steel / Deauville Blue / Textile

The lug width of the Oris Divers 65 01 733 7707 4065-07 5 20 24 is 20 millimetres. This technical parameter indicates the horizontal distance between the two lugs of the case where the strap is attached. It is easily measurable using a digital caliper positioned perpendicularly to the lugs, measuring from bar to bar. Any strap certified for 20mm will be compatible with this model without requiring structural modifications.

Strap selection depends on usage context. For formal occasions and elegant environments, we recommend alligator or shell cordovan leather with vegetable tanning in black or dark brown, which emphasises the case's austere aesthetics. For versatile daily use, fine-grained calf leather in black, midnight blue, or rum brown offers extended comfort and chromatic adaptability. For diving and aquatic environments, technical nylon NATO or FKM rubber ensures resistance to salt-water osmosis and durability without maintenance.

The procedure requires minimal tools: a spring bar tool and a clean work surface. Position the watch on anti-scratch cloth, then use the spring bar tool to insert the spring mechanism on one side, lifting the case gently to separate the old strap. Repeat for the opposite lug. Install the new strap by inserting the spring bar into both lateral grooves, verifying that the spring is perfectly retained. We recommend performing the operation slowly to avoid mechanical stress on the attachments.

Yes, provided it is certified for 20mm lug width and constructed according to standard mechanical tolerances. On milanostraps.it, every 20mm strap is individually verified to guarantee structural compatibility and durability of attachments with the Divers 65. Artisanal Casati Milano straps include technical specifications for anchoring and lug-hole perforation depth, ensuring performance equivalent to OEM straps without compromising wearing safety.

Leather strap longevity depends on frequency of wear, climate, and exposure conditions. Under normal conditions (moderate daily wear, temperate climate), a calf or alligator strap with vegetable tanning maintains structural integrity between 18 and 36 months. Humid-saturated environments, frequent water contact, or direct exposure to acidic perspiration reduce lifespan to 12-18 months. Synthetic rubber and NATO nylon ensure superior longevity (48-60 months) in aquatic contexts. Periodic maintenance (cleaning, conditioning with natural oils) significantly extends natural leather strap life.
