The Fleurier 103 watch movement, belonging to the hunter calibre period of time, incorporates a Breguet hairspring. To maintain a low profile while ensuring robustness, the movement includes an intermediate wheel positioned between the minute pinion and the remaining train components. Its name is derived from the arrangement of the four train bearings according to the four brightest stars in the Pleiades constellation. An optional Chronometer certificate from the Neuchatel Observatory is available for this movement. Noteworthy functions of the Fleurier 103 movement include stem winding and setting, as well as a sub second display.
