For its public launch, the new escapement by Audemars Piguet has been placed in the Cabinet N 5 model, belonging to the Tradition of Excellence collection, where it is joined by an original perpetual calendar with a linear display. Visually and aesthetically, this piece is both daring and spectacular. The very technical, three-dimensional, and cut-away architecture opens to the beating heart of the watch, nicely showcasing the new escapement, the double spring barrel, and the variable inertia balance. The modernity of this approach to watchmaking is emphasized even more by the very contem-porary design of the off-centred sub-dials: the dates in red surrounding the hour and minute dial, indicated by the tip of a red hand, the month appearing in a window at 12 oclock, the day in another window at 6 oclock, the leap-year cycle visible in the hour and minute dial between the numbers 12 and 1, an independent deadbeat seconds hand on the dial in an off-centred sub-dial at 7 oclock, and a power reserve indicator (7 days or 168 hours) displayed on another sub-dial positioned at 11 oclock. arity, readability, ease in utilization: the calendar indications are adjustable using a pushbutton and correctors located in the middle of the case; setting the time backwards is possible, even when the perpetual calendar is working, without risk of damaging the movement; the deadbeat seconds hand, which makes one jump per second, can be stopped without perturbing the watchs operation. At the back of the watch, the two barrels are visible and, as they turn, they gradually reveal the engraving, Audemars Piguet and Tradition d'Excellence. These two barrels can also be seen from the back side of the case, which is protected by a sapphire crystal and whose decorative geometry reinforces the technical aspect of the piece. Edited in a limited series of 20 pieces in platinum, this piece will most certainly delight collectors who can pride themselves on owning a watch that superbly marks the historic beginnings of a new escapement. Over time, Audemars Piguet has already announced its intention to gradually equip all of its watch production with this new escapement.
