The Heritage

The Oris Divers 65 01 733 7707 4051 OSC-PGH-Set embodies authentic dive watch philosophy from the 1960s, featuring the internal Oris 733 ND caliber specifically designed for this collection. The 40mm stainless steel case houses an automatic movement visible through a sapphire caseback, with a unidirectional 60-click bezel and 300-meter water resistance. The 20mm lug width accommodates compatible straps for conversion from the original steel bracelet.

FAQ

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

The lug width is 20 millimetres. This measurement represents the distance between the spring bar attachment points on the case and is essential for selecting compatible straps. Precise lug width correspondence prevents mounting issues and uneven wear.

Which strap is best suited for the Divers 65 01 733 7707 4051 OSC-PGH-Set?

Selection depends on usage pattern. For regular diving, vulcanised rubber or moisture-resistant NATO straps are recommended. For formal contexts alternating with occasional aquatic environments, black alligator maintains versatility. Vegetable-tanned leather is ideal if you seek patina development and intend stable wear in less formal settings.

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

Remove the original steel bracelet using a spring bar tool. Insert the new strap's spring bars into the case lugs, ensuring the retention springs click securely. Verify proper seating before any diving activity. The process typically requires 2-3 minutes with appropriate tools.

Is an aftermarket strap compatible with this Oris model?

Yes, provided the lug width is exactly 20 millimetres and the spring bars are of standard specification. Artisan-crafted straps in vegetable-tanned leather, alligator, shell cordovan and textiles install perfectly on the Divers 65 without case modification.

What is the lifespan of a leather strap on a diving watch like the Divers 65?

A vegetable-tanned leather strap subjected to regular diving has a serviceable life of 18-24 months before replacement becomes necessary. Occasional use extends longevity to 3-4 years. Moisture accelerates deterioration. Alligator, being denser, maintains integrity marginally longer. Immediate drying after water contact and preventive replacement before critical dives is advisable.
