Frequently asked questions

What is the lug width of the Oris Divers 01 643 7609 8585-Set MB?

The lug width of this model is 24mm. This measurement must be verified precisely between the two lugs of the case using a digital calliper. It is essential to check this measurement before ordering an aftermarket strap, as even small variations can compromise compatibility.

Which strap pairs best with the Oris Divers 01 643 7609 8585-Set MB?

For this 47mm instrument, we recommend vegetable-tanned Tuscan leather in tobacco brown or English veal, or technical nylon NATO for aquatic use. The choice depends on application: leather for daily elegance, NATO for diving and marine environments, vulcanised rubber for extreme stress testing. Milano Straps offers filterable cataloguing by 24mm lug width.

How do I change the strap on the Oris Divers 01 643 7609 8585-Set MB?

Remove the watch from your wrist. Using a spring bar tool (supplied with our premium straps), insert the lever under the case pin at the catch seat. Press gently outward to release the pin, remove the old strap, position the new one by aligning the holes with the lugs. Push the spring bar back until you hear the click. Verify the pin is securely seated on both sides.

Can I use an aftermarket strap on this Oris model?

Absolutely. The Divers 01 643 7609 8585-Set MB accepts any strap with 24mm lugs fitted with compatible spring bars. Milano Straps manufactures exclusively for this size and guarantees precise fit. Our artisanal vegetable-tanned leather and rubber straps are certified for equivalent or superior resistance to originals.

How long does a vegetable-tanned leather strap last on a watch like the Oris Divers?

With moderate use (3–4 days weekly), a vegetable-tanned Tuscan leather strap maintains structural functionality for 5–8 years. Degradation acceleration depends on UV exposure, constant humidity, perspiration and saline contact. The leather develops natural patina that increases aesthetic value. For ultra-marine environments (frequent diving), we recommend vulcanised rubber, which easily exceeds a decade of service.
