Frequently asked questions

What is the lug width of the Oris BC3 01 735 7641 4164-07 5 22 55?

The lug width of the Oris BC3 is 22mm. This measurement represents the distance between the two spring bars that attach the strap to the case. When purchasing a replacement strap, always verify that the product specification clearly indicates "22mm" to ensure perfect compatibility with your watch.

Which strap is recommended for the Oris BC3 01 735 7641 4164-07 5 22 55?

The BC3 accommodates multiple interpretations. For formal contexts, we recommend vegetable-tanned calf leather or alligator. For operational and casual settings, a NATO strap in ballistic nylon or an FKM rubber strap provides practicality and durability. Your choice depends on intended use and your aesthetic preference between elegance and sportive functionality.

How do I change the strap on an Oris BC3 01 735 7641 4164-07 5 22 55?

The strap is secured by two spring bars that pass through the case lugs. Use a dedicated spring bar tool to gently compress one bar and slide it out of the lug. Repeat for the second bar. Install the new strap by reversing this procedure. For safe replacement without risking scratches, we recommend professional assistance.

Which aftermarket straps are compatible with the Oris BC3?

Any strap with a 22mm lug width is compatible with the BC3 01 735 7641 4164-07 5 22 55. You can choose from leather (calf, alligator, shell cordovan), NATO fabric, vulcanised rubber, or modern technical textiles. Milano Straps offers a curated selection of 22mm straps, both classical and contemporary, customisable according to your preferences.

How long does a leather strap last on an Oris BC3?

A leather strap's longevity depends on tanning method and conditions of use. A quality vegetable-tanned leather strap, with regular care and periodic rotation with other straps, can last 3–5 years in daily wear. Prolonged exposure to humidity, perspiration, and UV rays shortens its lifespan. A NATO or rubber strap offers superior durability (7–10 years) with minimal maintenance.
