The BR 05 Chrono Blue Steel (Reference BR05C-BU-ST/SST) is an integrated-bracelet chronograph housed in a 42 mm satin-finished and polished stainless steel case. It features a sunburst blue dial configured with applied Super-LumiNova-filled indices, Arabic numerals at 12 and 6, and skeletonized hands. The bi-compax dial layout displays a 30-minute chronograph counter at 3 o'clock, a small seconds subdial at 9 o'clock, central chronograph seconds, and a date aperture positioned at 4:30.
The timepiece is powered by an automatic mechanical chronograph movement—designated by the manufacture as Calibre BR-CAL.326 (with earlier production variants cataloged under BR-CAL.301). The BR 05 collection adapts the brand's foundational "circle in a square" cockpit instrument DNA into an urban sports watch aesthetic.
Introduced in 2020, the BR 05 Chronograph adapted the strict "circle within a square" cockpit instrument concept, originally established by the 2005 BR 01, into a format utilizing an integrated steel bracelet. The 42mm steel case retains the brand's defining four structural bezel screws while softening the utilitarian angles into rounded corners that directly mirror the shape of the bi-compax sub-dials.
Powering the watch is the automatic caliber BR-CAL.301, which continues Bell and Ross's practice of utilizing established third-party Swiss movements by running on a modular ETA 2894-2 base operating at 28,800 vibrations per hour. This chronograph mechanism generates a 42-hour power reserve and is housed within a case sealed to provide 100 meters of water resistance.
