Bell & Ross has made its name as a benchmark in high-quality watchmaking and
the exclusive world of professional users with watches that totally respond to the
expectations of men living on the edge.
With long-haul travellers in mind, Bell & Ross has fitted the Instrument BR 01 with
a function focusing on time differences: the indication of a second time zone. With a
large central orange hand making it perfectly readable, the second time zone is read
over a 24-hour scale to distinguish AM from PM.
