Bell & Ross Watch BR 05 Chrono Green BR05C-GN-ST/SRB. Inspiration for Bell & Ross oscillates between sky and sea, but the Franco-Swiss watch brand that specialises in professional instruments always has its feet on the ground. With its green dial, the new BR 05 Chrono Green Steel celebrates the marriage between contemplating nature and a taste for urban performance. It’s a model of contemporary architecture in a chrono, designed for urban explorations.
