For February, which is a special case, the program cam is unable to offer a solution. Left to its own devices, the calendar would advance the date from the 28th or 29th in a leap year to the 31st. However, the owner can simply move the date on to the 1st of March via the crown.
From that point until the next necessary adjustment, the balance in the automatic movement will complete another 252,288,000 beats at a rate of 28,800 per hour. And while we are on the subject of impressive figures: the twin barrels give the movement a power reserve of seven days when fully wound. The reserve is useful for the improbable event that the rotor fails to generate any movement in the ceramic pawls resting on the ceramic automatic wheel because the watch has not been worn.
Expressed otherwise, a week is composed of 4,838,400 beats. But the seven-day power reserve display at 3 o’clock provides a punctual reminder. And when the movement finally does run down, the small seconds hand at 9 o’clock, which also shows whether the watch is running, comes to a standstill. The hand can be stopped, of course, by pulling out the crown if the owner wishes to set the watch.
