The Evolution of a Legend: The BR 05 Urban Identity
The Bell & Ross BR 05 Chrono Black Steel (BR05C-BLC-ST/SST) represents a monumental shift in the brand’s design philosophy. By integrating the bracelet directly into the 42mm case, Bell & Ross has entered the prestigious category of integrated sports watches. This piece takes the rugged “Circle within a Square” aviation DNA and refines it for a sophisticated urban landscape.
The Dial: Black Sunray Scintillation
The dial features a deep Black Sunray finish that catch the light in a radial pattern. The chronograph sub-dials at 3 and 9 o’clock utilize a “squircle” shape that echoes the case architecture, while the Super-LumiNova® filled applique numerals ensure perfect legibility in all conditions. A colour-matched date window at 4:30 maintains the dial’s flawless symmetry.
Mechanical Innovation: The 360° Oscillating Weight
Visible through the sapphire case back is the BR-CAL.326 automatic movement. This calibre is distinguished by its unique 360° skeletonised rotor, inspired by high-performance automotive wheel rims. This design allows for a clear view of the mechanical heart of the watch while providing a robust 60-hour power reserve.
