Frequently asked questions

What is the lug width of the Oris Divers 65 01 733 7707 4386-Set?

The lug width of the Oris Divers 65 01 733 7707 4386-Set is 20mm, measured as the internal distance between the strap attachment points from bar to bar. This dimension is standard in contemporary diving watch manufacture and allows broad strap compatibility. Always verify measurement with a digital calliper to ensure precise fit.

Which strap is most recommended for the Oris Divers 65 01 733 7707 4386-Set?

For the Divers 65 01 733 7707 4386-Set, alligator leather with vegetable tanning in cognac or hazelnut tones represents the most balanced aesthetic choice, enhancing the natural patina of the bronze case. Alternatively, a vulcanised rubber strap offers maximum functionality in aquatic environments, whilst NATO fabric provides casual versatility whilst maintaining the brand's aviation heritage.

How do I change the strap on the Oris Divers 65 01 733 7707 4386-Set?

Strap replacement requires removal of the attachment bars using a dedicated tool (spring bar tool). Gently press toward the case centre to release the internal spring, extract the old bar, position the new strap, and reinserert the bar until it clicks. The operation requires caution to avoid scratching the bronze case.

Which aftermarket strap is compatible with the Oris Divers 65 01 733 7707 4386-Set?

Any strap with a 20mm lug width is compatible with the 01 733 7707 4386-Set. Options are available in alligator, shell cordovan, veg-tanned calf, rubber, NATO fabric and nylon. Milano Straps offers curated collections dedicated to 20mm sizing, customisable according to material and chromatic preference.

How long does a leather strap last on the Oris Divers 65 01 733 7707 4386-Set?

Leather strap longevity depends on frequency of use and environmental conditions. In vegetable tanning with regular care (post-water drying, annual conditioning), lifespan is 3–5 years. Alligator and shell cordovan offer superior resistance, up to 7 years. Vulcanised rubber guarantees 4–6 years in intensive aquatic use.
