The Urban Revolution: A New Era for Bell & Ross
The Bell & Ross BR 05 Chrono Blue Steel (BR05C-BU-ST/SST) represents a definitive evolution in the brand’s design philosophy. Moving from the cockpit to the city, this watch takes the iconic square silhouette and refines it with an integrated bracelet. This design harks back to the luxury sports watches of the 1970s, now infused with the brand’s signature aviation-inspired functional aesthetics.
Architectural Case and Finishing
The 42mm case is a masterclass in finishing, utilizing vertical satin-brushed steel contrasted with mirror-polished bevelled edges. The “squircle” shape—a blend of a circle and a square—provides a bold presence on the wrist while remaining sophisticated. The rectangular pushers are seamlessly integrated with the crown guards, ensuring the lines of the watch remain unbroken and architectural.
The Dial: Sunray Blue Brilliance
The dial of this reference is finished in a dynamic Sunray Blue. This soleille finish interacts with light to create a radiant effect, shifting through various shades of blue. The two chronograph sub-dials at 3 and 9 o’clock are snailed and feature a rounded-square frame that echoes the case design. For optimal legibility, the applied numerals and skeletonised hands are filled with Super-LumiNova®.
