Sartory-Billard SB10 Jumping Hour Black Sapphire | Bracelet | LE300 | Pre-Order

The Sartory-Billard SB10 Jumping Hour Black Sapphire reimagines the independent luxury watch through a striking, contemporary display that eliminates traditional hands entirely. Instead, time is presented through ultra-thin sapphire discs, with a large jumping hour aperture at six o’clock delivering exceptional legibility and a dramatic, instantaneous change every hour. The minutes flow continuously along a luminous peripheral track, creating a compelling contrast between precision and motion. At the center, a smoked black sapphire cabochon replaces the dial, acting as a translucent veil that subtly reveals the underlying mechanics while shifting between reflective, opaque, and transparent tones depending on the light. This innovative layout transforms the watch into a modern statement piece, blending avant-garde design with practical readability.

Powered by a Swiss-made La Joux-Perret automatic movement with a 55-hour power reserve, the SB10 pairs reliable performance with a patented jumping hour module for crisp, accurate transitions. The 39.5mm stainless steel case, finished with a mix of polished and brushed surfaces, offers balanced proportions and 80m water resistance for everyday wear. A Super-LumiNova minute ring enhances nighttime visibility with a vivid glow, reinforcing the watch’s dynamic character. This luxury jumping hour watch stands out as a collectible independent timepiece, combining mechanical innovation, sapphire construction, and a bold, design-driven approach to modern horology.
