FAQ

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

The lug width is 20mm. This measurement is the standard for sports and diving watches in this category, and allows the use of a wide range of aftermarket straps in leather, NATO, rubber, and fabric.

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

The choice depends on intended usage: for diving, a NATO or technical elastomer strap ensures rapid drying and isothermal comfort. For daily and formal wear, vegetable-tanned leather in brown or black tones develops a natural patina that harmonises with the steel case. A fluoroelastomeric rubber strap represents an ideal compromise between practicality and refined aesthetics.

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

The procedure requires few tools: a spring bar removal tool or a small flat lever. Position the watch on a stable surface, locate the metal pin that connects the lug to the case, apply gentle lateral pressure to compress the internal spring, and carefully slide the old strap out. Insert the new strap by following the same procedure in reverse. The operation takes approximately 2-3 minutes and requires no specialist technical knowledge.

Which aftermarket straps are compatible with this model?

Any strap with a 20mm lug width is compatible. On milanostraps.it you will find a comprehensive selection of straps in artisanal leather, technical NATO, premium rubber, and fabric, all tested for this measurement. Materials include alligator, calf, shell cordovan, and synthetic fibres of quality.

How long does a leather strap last on the Oris Divers 65?

Longevity depends on material and usage. A high-quality vegetable-tanned leather strap typically lasts 3-5 years of daily wear before requiring replacement. Frequent exposure to salt water reduces durability to 1-2 years. A regenerated leather strap has slightly lower durability. A rubber or NATO strap, by contrast, guarantees 5-8 years of durability even with intensive use and frequent water contact.
