A bit of a hybrid of sorts.  It is at its heart a mechanical watch, but with a twist - an electronic module. I will let them describe it in their own words -

it incorporates an electronic module whose function is to measure the rate of the mechanical part. It has its own power source, separate from the rest of the movement. Positioned on the side of the case, a large retractable lever raises a dynamo which feeds the control micro-circuit. Thanks to its laser diode, it is able to collect two essential data relating to the movement. Pointing towards the balance, it reads its amplitude (an indicator of the movement’s state of health) and the rate deviation (which is an indicator of accuracy), while comparing them to an internal clock. The latter takes the form of a processor operating at a frequency of 16 MHz and serves as a reference oscillator, i.e. a benchmark.
