Sartory-Billard SB10 Jumping Hour Disco Ball | Bracelet | LE300 | Pre-Order

The Sartory-Billard SB10 Jumping Hour Disco Ball introduces a new perspective on contemporary independent watchmaking, transforming a once-impossible concept into a refined, highly wearable luxury timepiece. Defined by its innovative jumping hour complication, this Swiss-made watch replaces traditional hands with a bold display system built around ultra-thin sapphire discs. A wide aperture at six o’clock reveals oversized hour numerals for immediate legibility, while the minutes glide continuously along a peripheral track, creating a striking contrast between precision jumps and fluid motion. Housed in a 39.5mm stainless steel case with balanced proportions and 80m water resistance, the SB10 delivers a modern mechanical watch experience that prioritizes clarity, innovation, and visual impact.

Have you ever felt time?
A watch with no dial. A cabochon becomes the face of the watch itself. Not hidden behind glass, but exposed to the touch. You don't just see the material. You can feel it.


At the center, the dial is replaced by a sculptural cabochon, turning the watch into a fusion of haute horlogerie and contemporary jewelry design. In the Disco Ball edition, the multi-faceted guilloché surface captures and refracts light from every angle, creating a constantly shifting display that feels alive on the wrist. Beneath this artistic exterior, a Swiss automatic movement by La Joux-Perret with a 55-hour power reserve ensures reliable performance, enhanced by a patented jumping hour module for crisp transitions. The Sartory-Billard  SB10 Jumping Hour Disco Ball stands out as a collectible independent watch that merges technical innovation with tactile, design-driven storytelling.
