With the Flying Grand Regulator Open Gear Retrograde Second, ReSec for short, for the first time in its more than 35-year history, Chronoswiss presents a regulator timepiece in a striking 44mm case with an automatic movement. The C.301 is an exceptional automatic calibre developed by Chronoswiss. The refined Open Gear construction makes the regulator mechanism a main design element. It is put into the spotlight at the face of the dial, where the train wheel bridges in charge of the off-centre hour display were skilfully skeletonized and screwed firmly to the dial, which in turn becomes part of the movement. The eponymous retrograde seconds hand sweeps along the tracks of a 120 degree scale and every 30 seconds jumps back to the start.
