This ultra-thin perpetual calendar watch from Audemars Piguet is equipped with the Calibre 5133 movement, also known as RD#2, which took five years to develop. This movement has been innovatively upgraded based on the classic Audemars Piguet 2120 automatic movement. Its swing frequency reaches 19,800 times/hour and provides a power reserve of up to 40 hours. The new "48-month program gear" is used to cleverly eliminate the transmission gear between the calendar gear and the calendar gear, simplifying the original double-layer structure to a single layer and gradually reducing the thickness.

In addition, by redesigning and optimizing the component structure of the perpetual calendar function, these functions are integrated on a single-layer mainboard, evolving from the traditional three-layer reorganization to one layer, and at the same time, the size of the movement is increased by one circle, and the parts are laid flat. This innovation not only greatly reduces the thickness of the movement, but also improves the stability and efficiency of the movement.

The Audemars Piguet ultra-thin perpetual calendar watch not only achieved a breakthrough in technology, but its design also embodies the perfect combination of precision engineering and ergonomics. The number of parts in the movement has been reduced to 256, the dial is used as a bridge plate, and two innovative patented designs have been developed. This design not only reduces the weight of the movement, but also makes the watch lighter and improves the comfort of wearing.

In addition to ultra-thin technology, this watch also integrates a variety of complex functions, including perpetual calendar, day and night display, week, date, moon phase, month, leap year, hour, minute display, etc. The 4 o'clock position is a flat leap year display, the 8 o'clock position is a day and night display, and the aventurine moon phase disk above the disk is dazzling. The integration of these functions demonstrates Audemars Piguet's deep strength and innovative spirit in the field of complex function research and development.
