History

Bell & Ross was founded in 1992 by Bruno Belamich (Bell) and Carlos A. Rosillo (Ross), creating watches for professionals in extreme conditions — military, aviation, deep-sea diving. The defining BR 01 (2005) featured a square case inspired by cockpit instrument clocks, establishing the iconic circular-dial-in-square-housing identity. The BR-05 line, introduced in 2019, adapts that aesthetic for everyday urban wear with an integrated bracelet. The 36mm Blue Diamond Eagle proves cockpit-born design can serve as canvas for aventurine artistry without losing its bold geometric identity.
