Frequently asked questions

What is the lug width of the Bell & Ross Instruments BRS-HERI-CEM?

The BRS-HERI-CEM features 20mm lug width. This measurement is determined by the proportions of the 39mm square case and Bell & Ross's proprietary lugs system. Always verify this measurement when purchasing an aftermarket strap to ensure perfect mechanical compatibility.

Which strap do you recommend for the Bell & Ross Instruments Heritage ceramic watch?

For the BRS-HERI-CEM, we recommend a high-quality alligator strap or vegetable-tanned calf leather. Alligator maintains rigorous formal proportions and develops a fascinating patina over time, whilst calf offers greater comfort and versatility. For sports use, a vulcanised rubber strap provides durability without aesthetic compromise.

How do I change the strap on a Bell & Ross BRS-HERI-CEM?

Changing the strap on Bell & Ross Instruments models requires a specific spring bar removal tool. Position the watch on a soft pad, locate the small slots on the case at lug height, insert the tool and press gently to release the spring bar. Remove the worn strap and insert the new one, ensuring the bars lock correctly into their dedicated seats.

Are there aftermarket straps compatible with the Bell & Ross Instruments BRS-HERI-CEM?

Yes, numerous 20mm aftermarket straps are compatible with the BRS-HERI-CEM. On milanostraps.it you'll find a curated selection of customisable straps in sizes, colours and details (initials, thread colour). The Casati Milano atelier also produces bespoke straps with artisanal finishing and 18-month warranty, guaranteeing superior construction quality and verified mechanical compatibility.

What is the lifespan of a leather strap for the Bell & Ross Heritage?

A high-quality leather strap (alligatore, vegetable-tanned calf) maintains structural functionality for 3-5 years of intensive use, developing a fascinating aesthetic patina in the process. Actual lifespan depends on usage frequency, climate conditions and maintenance. Regular cleaning and protection from excessive humidity significantly extend strap life. After 4-5 years, replacement becomes advisable for safety and hygiene reasons.
