The "Chronometres a Resonance" are the only wristwatches in the world that make use of the phenomenon of resonance and enable a maximum precision. Using the effect of resonance, both balances oscillate in unison, but in opposite directions. In this manner, the negative effect of any wrist movement is reduced to a minimum.
