Calibre TM0803

8 DAY spring detent with fusee and chain

evolving naturally from the TM0801 launched in 2012, the calibre TM0803 develops the philosophy of revealing its beautiful precision engineering from the dial

By reversing respectively chain fusee drive and spring detent escapement, the two sine-qua-non specifications of a marine chronometer are now fully visible through the dial. Working as an infinitely variable gearbox, the former is responsible for delivering the mechanism an ever constant rate of energy, whereas the latter, with its escape wheel directly impulsing the balance without any anchor or lever in between, increases the escapement’s efficiency, joining together in the perfect combination for accuracy timepieces. Off-set Seconds at 3 o’clock, and Power Reserve Indicators at 9, complete this truly individual layout.
