The tourbillon was specifically designed
to compensate for the effects of gravity on the precision of pocket
watches, wristwatches move through constantly varying positions and thus
required an entirely different approach. Given the well-known fact that
keeping the regulating organ in a horizontal position generates the
best possible amplitude of the balance and thus considerably enhances
timing precision, Manufacture ZENITH decided to ensure that the
regulating organ and the escapement were indeed permanently kept in this
position. The rate of vibrations per second for this watch is
completely independent of its wearer’s movements.
