Frequently asked questions
What is the lug width of the Oris Divers 65 01 733 7707 4356-07 5 20 45?
The lug width of this model is precisely 20mm, a specification standard for sports and diving chronographs in the Oris Divers 65 collection. This width ensures compatibility with an extensive range of aftermarket artisanal straps, from leather solutions to specialised rubber options.
Which strap do you recommend for the Oris Divers 65 01 733 7707 4356-07 5 20 45?
The choice depends on intended use. For formal or mixed contexts, we recommend vegetable-tanned alligator or calf leather, which develop aesthetically alongside the bronze case. For regular diving or humid environments, FKM or butyl rubber offers consistent grip and rapid drying. Nylon NATO is the versatile option for quick transitions between contexts.
How do I change the strap on this watch?
Remove the strap using a dedicated spring bar tool, applying gentle lateral pressure to each anchor pin. Align the new strap holes with the lugs, ensuring the pin enters fully. Avoid excessive twisting during the operation to prevent damage to the threaded lug holes.
Which aftermarket straps are compatible with the Divers 65 01 733 7707 4356-07 5 20 45?
All straps designed for 20mm lug width are compatible. We recommend solutions with 4-5mm thickness and robust construction, suited to the weight and dynamics of a bronze and steel chronograph. Available through Atelier Casati Milano in vegetable-tanned leather, alligator, shell cordovan, NATO, and specialised rubber.
How long does a leather strap last on a diving watch like this one?
A vegetable-tanned leather strap, with proper maintenance, lasts 2-4 years in mixed daily use (terrestrial and occasionally humid). Salt exposure accelerates wear; we recommend periodic rotation with rubber straps during regular diving. Specialised rubber offers superior durability in marine contexts (3-5 years) with minimal maintenance.
