Sartory-Billard SB10 Jumping Hour Blue Aventurine | Leather Strap | LE300 | Pre-Order

The Sartory-Billard SB10 Jumping Hour Blue Aventurine (shown here on a stylish leather strap) reimagines the jumping hour complication through a contemporary lens, pairing innovative mechanical watchmaking with the tactile beauty of fine materials. At the center of the design is a striking blue aventurine cabochon, its deep celestial tones illuminated by countless shimmering inclusions that shift with every movement of the wrist. Mounted prominently at the heart of the watch, this polished gemstone-inspired element transforms the dial into a sculptural focal point, creating an emotional connection between wearer and timepiece. The result is a luxury Swiss watch that feels as much like wearable art as it does a precision instrument.

The SB10 delivers an entirely different approach to reading time. Rather than traditional hands, hours and minutes are displayed on ultra-thin sapphire discs that appear to float above the dial. A generously sized jumping hour aperture at six o’clock provides exceptional legibility, while the patented mechanism advances the hour display instantaneously with remarkable precision. The minutes glide continuously around the central cabochon, marked by a vivid red indicator traveling along a Super-LumiNova ring that glows brilliantly after dark. Powering this distinctive display is the Swiss-made La Joux-Perret G101A automatic movement with a 55-hour power reserve, housed within a 39.5mm stainless steel case featuring alternating brushed and polished finishes. Combining modern independent watchmaking, innovative jumping hour technology, and refined material craftsmanship, the SB10 offers a fresh and captivating interpretation of contemporary haute horlogerie
