Strap for Divers Sixty-Five 40 10 Years of Mr Porter

The lug width of the Oris Divers 65 reference 01 400 7772 4217-Set is 20 millimetres. This dimension is specific to the Divers 65 family and is compatible with the entire collection of 20mm straps available on Milano Straps, from leather to alligator to NATO fabrics.

The ideal strap depends on intended usage: for diving and water sports, the original fluoroelastometric rubber remains unmatched; for formal-elegant wear, an alligator strap with vegetable tanning in black or brown with integrated deployante clasp; for daily versatility, a NATO in heavyweight canvas or English calf in brown tone. The bronze unidirectional bezel benefits particularly from darker straps (black, brown, burgundy) that enhance visual contrast.

Use a spring bar tool to remove the metal barrels (spring bars) that connect the strap to the watch lugs. Insert the tool tip into the lug hole, push inward to compress the spring, then extract the barrel. Repeat on both lugs. Install the new strap by aligning the holes with the spring bars and press until you hear the locking click.

All straps with a 20mm lug width are compatible. Milano Straps offers Italian leather (alligator, calf, shell cordovan), NATO in ballistic-military canvas, and technical rubber. Ensure the strap width at the keeper is proportionate to the 40mm case diameter and suited to your intended usage context.

A vegetable-tanned leather strap (alligator, calf, shell cordovan) typically lasts 2-5 years with moderate daily wear. Longevity depends on: frequency of use, exposure to moisture and UV light, and quality of tanning process. Vegetable-tanned leathers develop patina that increases aesthetic appeal over time. A fluoroelastometric rubber strap lasts 4-7 years before losing elasticity and requiring technical replacement.
