Product Details
The Bell & Ross BR 05 GMT Sky Blue features a blue sunray dial and a clear, simple second time zone indicated by a fourth hand. The BR 05 GMT Sky Blue features "baignoire"-style rhodium-plated hands and indices coated with Super-LumiNova® that glows in the dark, and is powered by the Calibre BR-CAL.325, a high-quality self-winding mechanical movement.
Inspired by on-board flight instruments, the BR 05 is part of the family of watches with an integrated bracelet that merges with the case.
The GMT is a complication that provides practical information for travellers in the form of a second time zone. The hand on this second time zone performs one dial revolution every 24 hours. It displays the time on a 24-hour scale painted on the flange ring. This component is painted in two different colours: grey for the daytime (6 am to 6 pm) and blue for the night-time (6 pm to 6 am). To guarantee optimal legibility, a broad arrow-shaped white tip instantaneously indicates the time in the original country.
