Sartory-Billard continues to redefine modern horology with the SB04-E Ghost Silicon, a striking addition to the brand’s experimental Ghost series. Known for its exploration of reflection and invisibility, this collection transforms the way light interacts with watchmaking. The SB04-E Ghost Silicon Tantalum marks a bold evolution, crafted not from metal but from pure silicon, a material typically found in the microchip industry. This “subtle” edition pairs a sunburst smoked tantalum outer ring with a central disk of polished mirror silicon. Though identical in hue yet contrasting in texture, the two elements engage in a striking visual dialogue, creating a sense of perfect balance and quiet sophistication
Also available in a more "radical" full silicon edition.
Each silicon dial is cut and hand-assembled by Armand Billard in the Sartory-Billard workshop, with an astonishing precision of just 0.5 mm in thickness. The result is a hypnotic timepiece that feels both futuristic and meditative, a watch where time is reflected rather than read. The SB04-E Ghost Silicon is available with an integrated rubber strap. Both options echo the Ghost’s mirrored design language, uniting high-concept craftsmanship with wearable artistry for the collector who seeks the extraordinary
