Overview
Hours and minutes without hands
The Jacob & Co. Mystery Tourbillon 44MM, reference SN810.40.AA.UA.A, in an 18-carat rose gold case, 44 mm across and 21 mm high. Its 18-carat rose gold hour and minute rings are set with multicolour sapphires and white diamonds, with white diamond pointers, on a dark blue alligator leather strap with an 18-carat rose gold folding clasp.
The case is set with polygonal-cut white diamonds, the rings carry multicolour sapphires, and the hour markers and the two pointers are white diamonds.
This watch has no hands. Hours and minutes are shown on two concentric rings set with gems, and a pair of pointers marks the time. Jacob & Co. presents the display as a nod to mystery clocks, whose workings seemed to have no visible explanation.
Hand-wound calibre JCAM49 has 460 components and a 30-hour power reserve. Its tourbillon sits at the centre of the watch, has no upper bridge and turns on three axes, in 60, 120 and 120 seconds. Jacob & Co. says the carriage is covered for the first time by a flower-shaped decorative structure that turns with it. This version is a pièce unique.
