This H. Moser & Cie 1804-0222 is one of fifty white gold examples, distinguished by a dial cut from natural Falcon's Eye, a rare chatoyant quartz whose blue bands catch and throw light as the wrist moves. The Concept execution carries neither logo nor indices, opening only at six o'clock where a flying tourbillon turns. Power comes from the automatic calibre HMC 804, its one-minute flying tourbillon paired with an in-house double hairspring. The 18K white gold case measures 40mm across and 11.2mm thick, a poised profile that sits easily on the wrist. Against the shifting light of the stone, the open mechanism reads almost as ornament. Rarely does such restraint carry this much presence, and here it is the stone, not the tourbillon, that holds the eye.
