Bell & Ross Watch BRS Military Ceramic BRS-CERAM-MIL/SRB. True to its aeronautical origins, Bell & Ross has re imagined its iconic model, the BR 01, by introducing a sleeker and thinner creation, the BR S. With its monochrome khaki design, the BR S Military Ceramic celebrates the art of military camouflage. The khaki ceramic case is very resistant to scratches, unalterable in color and lightweight.
