Dewitt introduced the new Academia Endless Drive watch at the Salon International de la Haute Horlogerie (SIHH) 2018. It features an endless screw as the dial’s signature element which is fixed so that it can’t move longitudinally as it rotates. The hours and minutes are indicated with two discs located at 9 and 3 o’clock that rotate around a fixed central piece.
The Endless Drive is powered by the modified DeWitt 5050 automatic movement, entirely developed, produced and assembled by hand. The winding mechanism confers an unusual movement to the helical screw linked to the winding system. When the barrel is wound, the screw slides on its longitudinal axis showing a green indicator at 12 o'clock. As the amount of remaining stored energy (59 hours) decreases, the screw rotates. Once the barrel is fully wound, the endless screw slides on its longitudinal axis. The cost for this remarkable timepiece is approximately $41,000 (US).
