The Divers 65 01 733 7707 4051 OSC-BRB-Set, seen from the bench

The Oris Divers 65 01 733 7707 4051 OSC-BRB-Set is a 40mm stainless steel sports watch that faithfully reinterprets 1960s diving chronometer aesthetics. It features a unidirectional bezel with tachymeter scale, crown protection at 2 o'clock, and a transparent caseback. The watch is powered by the Oris 733 ND calibre, a manual-wind movement derived from the Sellita SW200-1, beating at 28,800 vibrations per hour. Water-resistant to 300 metres, it uses 316L stainless steel construction and a 20mm lug width.

Frequently asked questions

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

The lug width is 20mm. This measurement represents the distance between the two lugs on the case where the strap is inserted. It is essential to respect this dimension to ensure a stable and comfortable fit on the wrist.

Which strap is best suited for the Oris Divers 65?

It depends on usage. For formal elegance, we recommend alligator with vegetable tanning or black calf leather. For underwater functionality, a robust NATO or vulcanised rubber. Chocolate brown calf leather represents the ideal compromise between aesthetics and versatility, suitable for diverse contexts.

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

Obtain a spring bar tool. Insert the tip into the lateral groove of the lug, gently push to compress the internal spring, extract the lug. Repeat on the other side. Insert the new strap by aligning the holes with the lugs, press until the spring bar locks. The operation requires millimetre precision.

Can I use an aftermarket 20mm strap on this model?

Yes, provided the width is exactly 20mm. Bespoke leather straps from milanostraps.it are compatible with the Divers 65. Verify that the strap does not sit loosely between the lugs: precise fitting is a prerequisite for wearing stability.

What is the lifespan of a leather strap on this watch?

It depends on the material and usage. An alligator with vegetable tanning lasts 3-5 years if worn daily, owing to the natural fibrous structure. Calf leather resists 2-3 years. Vulcanised rubber lasts longer (5-7 years). Exposure to direct sunlight, perspiration and salt water accelerates wear. Periodic maintenance (gentle cleaning, rapid drying) extends its life.
