Strap for Oris BC3 01 735 7641 4733

The lug width of the Oris BC3 is 22mm. This standard measurement is taken between the lugs of the case and represents the construction specification for this model, compatible with the entire range of 22mm strap solutions.

For the BC3, a NATO strap in technical fabric or an alligator strap with vegetable tanning represent the optimal choices. The NATO maintains the tool watch's tactical heritage, whilst genuine crocodile leather develops a fascinating patina over time, transforming the appearance towards versatile elegance.

Use a spring bar tool or a thin plastic or nylon rod (never unprotected metal, to avoid scratching the case). Position yourself beneath the spring bar, press gently upward to release it, then slide out the old strap and insert the new one. Verify that both bars are inserted symmetrically before wearing the watch.

Absolutely. Artisanal aftermarket straps in 22mm are fully compatible with the BC3 without requiring modifications. A shell cordovan, alligator, or vegetable-tanned calf strap not only replaces the original, but often enhances the daily tactile and aesthetic experience, personalising your timepiece according to your style.

Durability depends on the material and usage. A vegetable-tanned calf resists 3-5 years of moderate wear, developing a desirable patina. Genuine alligator or shell cordovan can last 5-8 years. To extend lifespan, avoid direct intense sunlight, protect from excessive moisture, and occasionally apply peppermint oil or specific leather balm. FKM rubber resists up to 10 years if kept clean.
