Strap for Oris Divers 65 01 400 7772 4316

The lug width (misura ansa) of the Oris Divers 65 01 400 7772 4316 is 20 millimetres. This measurement represents the internal space between the two lugs of the case. To verify, place a ruler beneath the case and measure from internal wall to internal wall: you will obtain 20mm. This dimension is standard and grants access to a wide catalogue of compatible straps, both artisanal and industrial.

The ideal strap depends on intended use: for frequent recreational diving, choose heat-vulcanised rubber for saltwater resistance. For daily formal wear, natural alligator with vegetable tanning balances elegance and water repellency. For absolute practicality, a dense cotton NATO permits rapid underwater strap changes. The bronze case particularly benefits from straps that patina visibly—shell cordovan or vegetable-tanned calf—creating aesthetic synergy between case and strap.

Strap replacement occurs via small removable spindles (spring bars). Position the watch on a soft cushion with caseback facing upward. Use a spring bar tool (available on MilanoStraps) to compress the terminal of the spindle and slide it free from its seat in the case. Repeat on the opposite side. Insert the new strap, aligning the holes with the seats and pushing the spindles until they click. Verify symmetry before wearing.

Yes, entirely. Any artisanal or industrial strap with 20mm lug width is compatible with the 01 400 7772 4316. MilanoStraps' 20mm straps—in leather, NATO, rubber, shell cordovan—mount without case modification. Simply verify that the strap has standard holes or seats for 1.5mm diameter spring bars.

Leather strap durability depends on diving frequency, saltwater exposure, and maintenance. An alligator or vegetable-tanned calf strap, worn occasionally and rinsed after salt contact, lasts 3–5 years. If exposed daily to water (frequent diving), durability drops to 1–2 years. With regular maintenance—rapid drying after use—longevity increases significantly. A rubber or NATO strap endures longer (5–7 years) due to environmental resistance.
