History & Legacy of Bell & Ross

Bell & Ross is a French luxury watch brand founded in 1992 in Paris by designer Bruno Belamich and entrepreneur Carlos A. Rosillo. The brand originally collaborated with the German manufacturer Sinn to produce its early watches, marked “Bell & Ross by Sinn.” In 1998 Chanel acquired a minority stake in the company, and by 2002 Bell & Ross had moved its production to Switzerland in La Chaux de Fonds, ending its partnership with Sinn. Guided by the principles of legibility, functionality, precision and water resistance, Bell & Ross designs professional watches for pilots, divers, bomb disposal experts and other specialists. Its identity was firmly established in 2005 with the launch of the BR 01 collection featuring a square case inspired by aircraft cockpit instruments. Today Bell & Ross continues to produce Swiss made timepieces across aviation, diving and vintage lines, combining technical performance with distinctive design.
