Bell & Ross x 'Grail Watch Alain Silberstein

The Bell & Ross × Alain Silberstein Grail Watch 4 set brings Silberstein’s unmistakable Bauhaus-inspired design language to Bell & Ross’s square BR 03 platform, and these two references represent the most function-driven members of the trilogy. The BR 03-92 Marine 22 Ref. BR0392-D-AS-CE/SRB is a true 300-meter diver housed in a 42mm × 42mm matte black ceramic case. Its two-tone ceramic dive bezel uses a bold red section for the final 20 minutes, while Silberstein created an oversized “Maxi” handset specifically for this model to maximize underwater legibility. The geometric hour, minute, and seconds hands use contrasting blue, red, and yellow luminous elements against the matte black dial. Inside is the automatic BR.CAL-302, operating at 28,800 vibrations per hour with 25 jewels and approximately 42 hours of power reserve. The Marine 22 was limited to only 100 numbered pieces worldwide. Grail Watch Pte. Ltd.
The BR 03-94 Krono 22 Ref. BR0394-AS-CE/SRB takes the same 42mm × 42mm black ceramic architecture and transforms it into a playful mechanical chronograph. Its dial incorporates five of Silberstein’s signature geometric hands, including a red circular hour hand, blue arrow minute hand, yellow S-shaped central chronograph hand, blue triangular 30-minute counter hand, and yellow running-seconds hand. Even the controls become part of the design: the chronograph pushers receive contrasting yellow and blue lacquered inserts, while the crown carries Silberstein’s signature red triangle. Power comes from the automatic BR.CAL-301 chronograph caliber, with 37 jewels, a 28,800-vph frequency, and approximately 42 hours of power reserve, while water resistance is rated to 100 meters. Like the Marine, the Krono 22 was limited to just 100 numbered examples. Most significantly for a complete collector set, numbers 1–50 of both references were reserved exclusively for the matching three-watch Trilogy box sets, of which only 50 were produced worldwide.

Bell & Ross was founded in 1992 by Bruno Belamich and Carlos Rosillo with a mission to create watches that meet the extreme demands of aviation professionals, divers, and military units. Drawing inspiration from cockpit instrumentation, the brand’s iconic square-case design — first seen in the BR 01 — quickly set it apart in the world of modern tool watches. Designed in Paris and manufactured in Switzerland, Bell & Ross blends tactical functionality with refined industrial design.

Over the years, the brand has expanded its reach with collections like the BR 03, BR 05, and Vintage series, while maintaining its core philosophy: legibility, reliability, and performance under pressure. Today, Bell & Ross is celebrated for its distinctive aesthetic and dedication to purpose-built watchmaking that transitions effortlessly from cockpit to city street.
