Bell & Ross is a Swiss watch company headed by French designers Bruno Belamich and Carlos A. Rosillo. The brand was launched in 1993, using the Frenchmen's designs, and engineered by a German watchmaker, Sinn.[1]

Bell & Ross's first watches were virtual re-issues of Sinn models, and carried the Bell & Ross logo, as well as Sinn's. The partnership ended in 2002, when Bell & Ross began autonomous production in La Chaux-de-Fonds, Switzerland.[2]
