Strap for Oris Divers 65 01 733 7720 4057

The lug width of the Oris Divers 65 01 733 7720 4057 is exactly 21mm. This measurement is determined by the geometry of the 42mm case and the design of the onion crown. To verify strap compatibility, measure the distance between the inner edges of both lugs: it must correspond precisely to 21mm. Straps measuring 20mm or 22mm will not guarantee a proper fit and may compromise the structural integrity between case and crown.

For the Divers 65 01 733 7720 4057, we recommend three options based on your priorities. An alligator strap with vegetable tanning in brown represents the ideal aesthetic compromise, offering sartorial refinement whilst maintaining a degree of functionality. A NATO strap in technical nylon, particularly in navy blue or black, is the most faithful choice to the watch's diving heritage and guarantees maximum durability in humid environments. Finally, a black vulcanised rubber strap expresses the true professional-tool nature of the Divers 65, with uncompromised grip and saltwater resistance.

Changing the strap on the Divers 65 01 733 7720 4057 requires removing the spring bars that connect the strap to the lugs. Obtain a spring bar removal tool or small flat metal lever (do not use sharp objects that might scratch the case). Insert the tool into the gap between the lug and the strap, applying gentle pressure to compress the internal spring of the bar. Once extracted, you can slide off the old strap and insert the new one, ensuring it is correctly aligned before reinserting the spring bar. Verify that the new strap features a 21mm lug width to guarantee a precise fit.

Yes, quality aftermarket straps are fully compatible with the Divers 65 01 733 7720 4057, provided they respect the 21mm lug width. Artisan-crafted straps made from noble materials—alligator, vegetable-tanned calf, shell cordovan—often offer superior construction quality to original straps, guaranteeing longevity and aesthetic development over time through natural patina. Choosing an aftermarket strap allows you to fully personalise your Divers 65, adapting it to your aesthetic preferences and lifestyle.

The lifespan of a leather strap depends on the specific material, conditions of use and maintenance. A vegetable-tanned calf strap maintains acceptable wear for 2–3 years of daily use, whilst developing a beautiful patina that enhances its character. An alligator or shell cordovan strap can last 3–5 years or longer, thanks to the greater fibre density of the leather. In very humid environments or with frequent diving, we recommend using a rubber or NATO strap, whilst leather straps should be alternated and carefully dried after prolonged moisture exposure. With proper maintenance and periodic cleaning, a quality leather strap renews and improves over time.
