Calibre Octa A Horological Ideal_ The construction of the Octa calibre has less powerful ties with the history of horology than the constant-force device or resonance models do. Nevertheless, it symbolizes a horological ideal: giving timekeepers the highest possible degree of precision and autonomy.
Page 3
The calibre retains the characteristics of the classic Octa with: a 160-hour power reserve and a variable inertia balance wheel for an optimum yield that offers each model of the Octa line an irreproachable stability.

If the watch is stopped, turn the crown in position 0 about a dozen times anticlockwise. All models of the Octa Line offer an exceptional power reserve of 160 hours. The Octa models can operate above those 160 hours but the precision is thus not as efficient. Setting the date : Pull the crown in position 1 and turn anticlockwise.
