The BR-01 BR0196-ALTIMETER, seen from the bench

The BR-01 Altimeter from Bell & Ross houses the ETA 2896 caliber with hour, minute, second and big date functions. The model features a design inspired by aircraft instrumentation with a dial that replicates the aesthetic of an altimeter. The case maintains the characteristic square shape of the BR-01 with the crown positioned at 3 o'clock.

Frequently asked questions

What is the exact lug width of the Bell & Ross BR-01 BR0196-ALTIMETER?

The lug width of the Bell & Ross BR-01 BR0196-ALTIMETER is 24mm. This dimension is specific to the model and derives from the integrated lug geometry. To measure it correctly, use a calliper positioned between the inner lug pins, measuring from wall to wall. It is essential to respect this exact measurement to ensure proper fitment of aftermarket straps without compromising the integrated lugs.

Which strap material is most recommended for the BR-01 BR0196-ALTIMETER?

Nile alligator is the ideal material for the BR-01 BR0196-ALTIMETER: its regular and flat texture perfectly mirrors the case's squared geometry. Excellent alternatives include shell cordovan for formal elegance, or woven NATO/vulcanised rubber for those preferring historical avionic authenticity. The choice depends on use: leather for formal-professional contexts, fabric or rubber for intensive daily operability.

How do you change the strap on the Bell & Ross BR-01 BR0196-ALTIMETER?

The BR-01 BR0196-ALTIMETER features integrated lugs, which simplifies strap replacement: simply extract the security pin using a dedicated tool or small screwdriver, remove the old strap and insert the new one. The pin must be reinserted from both sides until fully locked. We recommend performing the operation on a soft surface (cloth) to avoid scratches. If unsure, consult an expert.

What is the best compatible aftermarket strap solution for the BR0196-ALTIMETER?

Aftermarket straps compatible with the BR0196-ALTIMETER must strictly respect the 24mm lug width. Recommended options include: black or brown Nile alligator, vegetable-tanned regenerated calfskin, dark shell cordovan, or satin-finished woven NATO for historical authenticity. Milano Straps offers customisable straps in width, colour and stitching details, as well as bespoke creations at the Casati Milano atelier.

How long does a leather strap last on the Bell & Ross BR-01 BR0196-ALTIMETER?

Leather strap durability depends on usage intensity, material quality and maintenance. An alligator or shell cordovan strap, with moderate daily use and regular maintenance (cleaning and conditioning every 6-12 months), can last 5-8 years. Vegetable-tanned calfskin straps develop patina quickly but retain structural integrity for 4-6 years. Woven NATO, more durable, can exceed 10 years. Milano Straps guarantees 18 months on custom straps.
