FAQ

What is the lug width of the Oris Divers 65 01 733 7707 4094-SET?

The lug width (ansa measure) of the Oris Divers 65 01 733 7707 4094-SET is exactly 20mm. This measurement represents the precise geometric space between the case lugs and requires straps manufactured to exacting specifications. It should not be confused with reduced (18mm) or enlarged (22mm) variants.

What strap material is recommended for the Oris Divers 65?

For the Oris Divers 65, we recommend vegetable-tanned alligator for a discreet formal profile, shell cordovan for moisture resistance and accelerated patina development, English-grain calfskin for daily comfort, and rubber straps for actual diving use. Each material emphasizes a different purpose of the watch, from subtle daily wear to technical underwater functionality.

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

The Oris Divers 65 features a screw-through lug system, meaning the strap passes completely through the lugs. To change the strap, remove the two screws located inside the lugs using a proper watch tool, extract the old strap, and insert the new one by aligning it with the screw holes. Tighten the screws gently, ensuring the strap is perfectly centred.

Which aftermarket straps are compatible with the Oris Divers 65 01 733 7707 4094-SET?

Any strap with a 20mm lug width is compatible with your watch. Milano Straps offers a complete collection of 20mm straps in leather, NATO, and rubber, manufactured to constructive standards that guarantee proper seating on your case. Compatibility is determined solely by the lug width measurement.

What is the lifespan of a leather strap on an Oris Divers 65?

A quality leather strap (alligator, calfskin, shell cordovan) on an Oris Divers 65 has an estimated lifespan of 3 to 7 years with daily use, depending on humidity exposure, direct sunlight, and maintenance frequency. Vegetable-tanned leather tends to develop a patina that improves aesthetic appeal but gradually reduces mechanical resistance over time. Rubber straps typically last 4-5 years before showing signs of degradation.
