The Divers 65 01-733-7707-4354 / Timeless, seen from the bench

The Divers Sixty-Five 40 is Oris's contemporary manifesto of function-first design with authentic vintage aesthetic. The 40mm case combines stainless steel and bronze—a metal that naturally oxidizes, developing a unique patina over time. Powered by the Oris 733 automatic movement with 38-hour power reserve, date indicator, and 300-meter water resistance, it features a unidirectional bezel and anti-reflective sapphire crystal. The 20mm lug width ensures compatibility with aftermarket straps.

Frequently asked questions

What is the lug width of the Oris Divers 65 01-733-7707-4354 / Timeless?

The Divers 65 features a 20mm lug width. This measurement is taken by inserting a digital calliper between the two spring bar pins on the case lug. It ensures full compatibility with Milanostraps' 20mm strap collection and contemporary artisanal aftermarket straps.

Which strap is recommended for the bronze-cased Divers 65?

For the bronze version, we recommend a genuine alligator strap (chocolate brown or black) or vegetable-tanned calf leather. These materials create an aesthetic dialogue with the bronze patina, evolving alongside your watch over time. A canvas NATO is ideal for daily wear and frequent diving.

How do you change the strap on the Divers 65?

The Divers 65 uses straight spring bars inserted through the lug pins. Use a spring bar tool, position the watch lug-side down, gently press the bar to release it from the case shoulder, remove the old strap, and insert the new one. A simple operation, performable at home or at an authorised service centre.

Are aftermarket straps compatible with the 01-733-7707-4354?

Yes, all straps with a 20mm lug width are compatible. Milanostraps offers a curated selection of artisanal leather, NATO, and rubber straps certified for this measurement. The fit is precise thanks to standardised lug width and spring bar specifications.

How long does a leather strap last on a sports watch like the Divers 65?

A quality leather strap (alligatore, vegetable-tanned calf) on a sports watch typically lasts 3–5 years with moderate daily use. Frequent water and humidity exposure reduces longevity; in such cases, a NATO or vulcanised rubber are more durable choices. Leather patina nevertheless evolves, becoming increasingly characteristic over time.
