I suppose you refer to their new oscillator
"That oscillator, beating at an unprecedented 288,000 vibrations an hour, about 40Hz, brings a motherlode of modern innovation to such a classic execution. At that rate, the Slimline Monolithic Manufacture ticks at 10 times the speed of most mechanical movements.
Moreover, CEO Peter Stas collaborated with Dr. Nima Tolou of the experimental component maker Flexous to create an oscillator with such precision to conform to a size appropriate for a wristwatch and to still enable an 80-hour power reserve for the timepiece."
I am not convinced it is the same mechanism as, to my understanding, before official report, Vincent CALABRESE proposes a new "mechanical" system.
To be followed with higher interest.
