The Tungsten Semikonductor — design concept featuring silicon wafer dial with circuit patterns and tungsten carbide case

The dial is cut from an actual silicon wafer—the same material that runs inside every processor, every GPU, every chip that has defined modern computing. Circuit trace patterns are visible beneath the sapphire crystal. The pathways that once carried electrical signals now mark hours and minutes.

The case is tungsten carbide—9.5 on the Mohs hardness scale, just below diamond. It's virtually scratchproof, and dense enough that you'll feel the weight the moment you pick it up. Blued steel hands sweep across the silicon dial. A moon phase complication at 6 o'clock tracks the 29.5-day lunar cycle. The Sellita SW280-1 automatic movement powers everything with a 38-hour reserve.

39mm. Sapphire crystal front and back. Anti-reflective coating on both sides.
