The Sartory-Billard SB04-E Tantalum Hand-Engraved is a rare expression of artistry and innovation in modern haute horlogerie. Renowned for its density, resistance, and corrosion-proof qualities, tantalum is notoriously difficult to work with, making the SB04-E’s delicately hand-engraved feather-like dial lines an extraordinary achievement.
Framed by a tantalum outer ring finished with a fume sunburst effect, the dial reveals incredible depth and texture, enhanced by a sapphire disk with diamond-polished chamfered edges and luminous Super-LumiNova® BGW9 detailing. Even-numbered diamond-cut metal markers and Sartory-Billard’s signature Y-shaped odd-numbered markers, inspired by the Eiffel Tower, honor the founder’s Parisian roots while adding a distinctive identity to this luxury artisanal watch.

Every design detail of the SB04-E Tantalum reflects the brand’s dedication to refined proportions and contemporary elegance.

With 100 meters of water resistance, a robust tantalum construction, and meticulous finishing, the SB04-E Tantalum is a bold statement of craftsmanship, innovation, and exclusivity for collectors who appreciate the extraordinary
