Introduced at Baselworld 2015, the Breguet 7077 mechanism is built in a truly original and ingenious way, and the chronograph mechanism is completely independent and autonomous. There is no interaction between the timekeeping indication and the chronograph. On one side, an independent “sub-movement” – composed of one barrel, one gear train, and one oscillator – drives the indication of the time. On the other side, an independent mechanism, with its own energy source, gear train and oscillator, regulates the chronograph functions. As a consequence, there is no interference in energy consumption and the rate of the timekeeping movement remains unaffected when the chronograph is started.
With this timepiece, Breguet demonstrates once again its capability to keep innovating while respecting the watchmaking tradition and the heritage of its founder, Abraham-Louis Breguet, unanimously recognised as the most influential watchmaker ever lived. This is a new type of mechanical watch movement that is emerging in this model but also a new approach of an independent chronograph.
