The Bell & Ross Space 1 is an early model by Bell & Ross that was produced by Sinn. It is identical to the Sinn142. This watch features a cushion-shaped case with internal rotating bezel, and is powered by the self-winding caliber 5100.
Chronograph movement with central minute counter. Day and date display; additional fixed 24h hand. Loved for its robustness though its construction is far from elegant.
