Frequently asked questions

What is the lug width of the Oris Divers 65 01 733 7707 4051 OSC-PAR-Set?

The lug width of the Oris Divers 65 01 733 7707 4051 OSC-PAR-Set is 20mm. This measurement is uncommon in contemporary watchmaking and requires careful selection of compatible straps. Always verify that the spring bar seats smoothly within the lug without lateral play.

Which is the best strap for the Oris Divers 65 01 733 7707 4051 OSC-PAR-Set?

The choice depends on intended use. For formal elegance, premium alligator or vegetable-tanned calf leather. For aquatic environments and robust daily wear, ballistic nylon NATO or FKM rubber. The dial's intense red naturally harmonises with warm-toned straps (cognac, tobacco).

How do I change the strap on an Oris Divers 65?

Insert the spring bar tool underneath the internal lug section, lifting gently outward. The tension spring will yield, allowing the removal of the spring bar. Repeat on both sides, then position the new strap, aligning the lug slots with the case attachments.

Which aftermarket straps are compatible with this model?

Any strap with a 20mm lug width is compatible. milanostraps.it offers a curated selection of artisanal straps in leather, alligator, shell cordovan and textiles, all prepared for rapid shipping and customisable upon request.

How long does a leather strap last on this watch?

A premium-quality leather strap (alligator, vegetable-tanned calf) typically lasts 3–5 years with daily wear and proper maintenance. Longevity depends on ambient humidity, cleaning frequency and exposure to direct heat. Rubber and NATO straps endure longer (5–7 years) but still require periodic inspection.
