Frequently asked questions

What is the lug width of the Oris Divers 65 01 733 7720 4054?

The Oris Divers 65 reference 01 733 7720 4054 features a 21-millimetre lug width. This specific measurement is characteristic of the Divers Sixty-Five collection and allows only straps manufactured to this standard to be fitted. Milano Straps offers a comprehensive selection of 21mm-compatible straps, from vegetable-tanned leather to NATO fabrics and rubber solutions.

Which strap is best suited for the Oris Divers 65 01 733 7720 4054?

For the Divers Sixty-Five, the ideal strap depends on intended use and aesthetic preference. Natural alligator leather with a dark patina enhances the vintage vocation of the dial, whilst supreme vegetable-tanned calf leather offers visible ageing over time. For intensive underwater use, vulcanised rubber provides salt-water resistance and durability. Milano Straps recommends assessing the environment: elegance for formal occasions, robustness for marine expeditions.

How do I change the strap on my Oris Divers 65 01 733 7720 4054?

The Divers Sixty-Five is fitted with fixed lugs. To replace the strap, you must remove the lug pins using a dedicated spring bar tool. DIY without experience is not recommended, as incorrect handling could scratch the case. Milano Straps provides detailed tutorials and, upon request, personalised installation assistance for your new 21mm strap.

Can I fit an aftermarket strap on my Oris Divers 65 01 733 7720 4054?

Yes, any strap with a 21mm lug width is compatible with the Oris Divers 65 01 733 7720 4054. Milano Straps' bespoke straps are crafted to the highest quality standards and fit the case perfectly. It is essential to verify that the strap does not protrude laterally from the lugs and that the attachment width is precisely measured.

How long does a leather strap last on an Oris Divers 65 01 733 7720 4054?

Strap durability depends on material and use patterns. Supreme vegetable-tanned leather, with regular maintenance (occasional cleaning and conditioning), can endure 5–7 years of daily wear. Natural alligator is more resilient and readily reaches 10 years. If your Divers 65 is frequently used in water or humid environments, rubber or NATO solutions are recommended—materials that are practically indestructible.
