A plurality of frequencies
The three channels are designed around 18,000, 25,200 and 28,800 vibrations per hour. The COMBINER R3 mechanically averages their rates; the displayed time follows that combined output.
ACC-1
Calibre / 01
Three regulators.
One mechanical voice.
Three independent escapements run at different frequencies. A mechanical combiner brings their rates together into a shared output.

Reserve and frequencies are design values from the current engineering documentation. They are not a claim of measured performance of a finished watch.
Behind the architecture
A closer
look.
Computation, made mechanical
Differentials, a summing ring, an isochronism corrector and channel-consensus indicators make the internal state visible. Deadbeat seconds and a days-since-synchronisation counter give the display its own mechanical language.
An architecture you can read
Skeletonised plates and bridges expose the relationship between the energy train, the regulators and the display. The current v1.2 CAD assembly contains 583 parts, including 363 unique components.
