Strap for BR 01 93 GMT 24H

The lug width (misura ansa) of the Bell & Ross BR-01 BR0193-GMT is 24 millimetres. This measurement is essential for strap compatibility: any aftermarket strap must be exactly 24mm wide at the terminals that fit into the case lugs.

Given the functionalist, aeronautical aesthetic of the BR-01, we recommend a black or slate-grey alligator strap, or a rigid blue-night NATO strap. If you prefer a more versatile material with visible ageing, vegetable-tanned calf leather in medium chestnut tones develops a patina over time that reinforces the instrument's character.

Changing the strap on the BR0193-GMT requires a spring bar tool. Position the tool's tip beneath the lug terminal and apply gentle vertical pressure to compress the internal spring, then extract the pin. Repeat on both sides. Align the new strap's holes with the lugs, insert the pins, and release the pressure. Verify the locking mechanism before wearing the watch.

Yes, any 24mm strap is compatible with all Bell & Ross watches (and other brands) using the same lug width. Consult your model's compatibility chart. However, for aesthetic reasons, we recommend evaluating case proportions: a strap designed for the BR-01's square geometry may appear unbalanced on a round case.

Lifespan depends on use, climate, and maintenance. A quality natural leather strap, under normal conditions (not daily aquatic exposure), typically lasts 18–36 months before replacement. Vegetable-tanned leather ages visibly but maintains structure longer than chemical tannages. Constant exposure to humidity, perspiration, and sunlight significantly shortens longevity.
