Frequently asked questions

What is the lug width of the Oris BC3 01 735 7641 4764?

The Oris BC3 01 735 7641 4764 features a 22mm lug width. This measurement represents the distance between the two lateral lugs of the case and is crucial for purchasing a compatible strap. Measuring the lug width correctly prevents compatibility errors that would compromise both the aesthetics and practicality of use.

Which strap do you recommend for the Oris BC3 01 735 7641 4764?

For the BC3 01 735 7641 4764, we recommend alligator straps with vegetable tanning, shell cordovan, or NATO straps in technical fabric. If you intend to use the watch in aquatic or sports environments, vulcanised rubber straps guarantee maximum resistance. The choice depends on your context of use: formal elegance calls for alligator, technical versatility suggests NATO or rubber.

How do I change the strap on my Oris BC3 01 735 7641 4764?

Changing the strap on the BC3 01 735 7641 4764 requires a specific tool: a spring bar removal tool. This small fork-shaped lever allows you to compress the internal spring of the lug, enabling disengagement from the case lugs. Insert the pointed tip into the lug slot, compress slightly, and slide the strap outward. The reverse process secures the new strap: align the holes with the lugs, insert the spring bars, and verify they are completely locked.

Is the strap you sell compatible with my Oris BC3 01 735 7641 4764?

All straps from our 22mm collection have been tested and are fully compatible with the Oris BC3 01 735 7641 4764. Each product is checked to ensure that the spring bars insert correctly into the lugs. Before ordering, we recommend verifying that your watch indeed has 22mm lugs by measuring the distance between the two lateral lugs.

How long does a leather strap last on the BC3 01 735 7641 4764?

The lifespan of a leather strap depends on usage and maintenance. An alligator strap with vegetable tanning can last from 3 to 5 years with daily use, thanks to the natural robustness of this leather. Shell cordovan, being denser, can last 6-7 years. Longevity increases if the strap is subjected to periodic maintenance: gentle cleaning, air drying after moisture, avoiding prolonged sun exposure. We recommend having spare straps to distribute wear.
