Oris
Divers 65 01 733 7707 4386-Set— lug 20mm

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.

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.

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.

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.

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.
