Yes. Bell and Ross references from 20mm to 24mm lug width are natively supported. BR 03-92 uses 24mm - fully compatible.

Which Bell and Ross models have guides?

The BR 03-92 has a full reference table covering all 89 variants - steel, ceramic, bronze, carbon, and PVD.

¿Smartlet daña o modifica mi reloj mecánico?

No. Smartlet reemplaza tu correa de reloj estándar utilizando el sistema de pasador de resorte existente. No realiza ninguna modificación permanente en la caja, asas o esfera del reloj. El proceso es completamente reversible en segundos. Tu reloj mecánico no se ve afectado y puede usarse de forma independiente en cualquier momento reinstalando su correa original. Smartlet está diseñado con tolerancias de relojero y probado con el mismo cuidado que se dedica a los relojes con los que se empareja.

Bell & Ross compatibility

Wear a smartwatch with your Bell & Ross

In short Smartlet One is compatible with all Bell & Ross BR 01, BR 03, and BR 05 references. Lug widths range from 20mm to 24mm, natively supported with no adapter. Installation uses the standard spring-bar system - no modification to the watch, fully reversible in seconds.

Bell & Ross built its identity around one constraint: the cockpit instrument. The square case, the high-contrast dial, the four screws - every detail is legible at arm's length under stress. The BR 03 became a collector reference not because it chased history, but because it solved a problem. Smartlet One sits on the same wrist without competing with that logic. The square case remains untouched. The spring bars carry the load, as they always have.

Wear yours How it works

The problem

Choosing between health data and horological heritage every morning.

The solution

Smartlet One replaces your Bell & Ross's strap via the standard spring-bar system and positions your smartwatch on the same wrist. Both watches run simultaneously, with no modification to the watch and full reversibility in seconds.
