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\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003e\u003cem\u003eAlso available in a more \"radical\" full silicon edition on a \u003ca rel=\"noopener\" href=\"https:\/\/www.osterjewelers.com\/collections\/sartory-billard\/products\/sartory-billard-sb04-e-ghost-full-silicon-strap\" target=\"_blank\"\u003estrap\u003c\/a\u003e or \u003ca href=\"https:\/\/www.osterjewelers.com\/collections\/sartory-billard\/products\/sartory-billard-sb04-e-ghost-full-silicon-bracelet\" rel=\"noopener\" target=\"_blank\"\u003ebracelet\u003c\/a\u003e.\u003c\/em\u003e\u003cbr\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp data-start=\"715\" data-end=\"1381\" data-is-last-node=\"\" data-is-only-node=\"\"\u003eEach 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.
