Bell & Ross is a French watch company headed by the French and Swiss designer Bruno Belamich and businessman Carlos A. Rosillo. The brand was launched in 1992, and the first watches were designed by Belamich and Rosillo and made by a German watchmaker, Sinn. Watches such as the BR Instrument have been designed to replicate the shape of a cockpit instrument taken from an aircraft. The BR02 range caters for diving professionals through the use of highly legible dials and cases water resistant to withstand 1000 metres of pressure. Another offering is the Hydromax; which contains hydraulic fluid within the case to counteract the effects of external pressures. 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 its own independent production in their facilities La Chaux-de-Fonds, Switzerland. The aesthetic appeal of Bell & Ross is mirrored in their four design principles, namely optimal water resistance, highly accurate Swiss mechanical movements like the ETA Valjoux, clear visual indicators, such as those found on aircraft instrument panels, and special functions intended for specific uses. They also have a quartz line with the identical characteristics (except for the type of movement utilized) called the BR S that utilizes the highly regarded ETA 980.163 15 jewel quartz movement.
