Audemars Piguet- Jules Audemars Grande Sonnerie Dynamograph

The Audemars Piguet Jules Audemars Grande Sonnerie Dynamograph watch is an extraordinary achievement of horological mastery as well as superb traditional watchmaking knowledge and craftsmanship. A testament to the expertise of Audemars Piguet in the realm of great watchmaking complications, this extraordinary timepiece takes the celebrated complication of the repeater to its ultimate level. The manually wound movement, constructed by Audemars Piguet and their famed movement specialist Renaud et Papi, contains well over 400 individually hand-finished pieces.

This phenomenal mousetrap of wheels, pinions, racks, snails, and springs offers first of all, a minute repeater, which can be activated on request to chime the hours, quarter hours, and individual minutes; unlike most repeaters however, which indicate quarter hours with a two-gong high/low chime, the Sonnerie movement has a three-gong carillon chime, which offers both additional complexity, as well as a remarkably beautiful and distinctive quarter-hour chime. In addition to the minute repeater, the Audemars Piguet Jules Audemars Grande Sonnerie watch offers both big and little strike ("Grande et Petite Sonnerie") modes. This remarkable complication allows the watch to be set in such a way that hours and quarter hours are struck off automatically throughout each hour, (Grand mode), or to strike only the hours in passing (Petite mode). Since this complication demands so much energy to operate, the movement of this Audemars Piguet Grande Sonnerie watch features mainspring barrels dedicated to both the movement, and the strike works.

Functions of the watch.

• Great tone mode, it automatically rings the hours and quarters.
• Small Ring mode, it automatically rings the hours
• Silence: no ring feature is active. It is essential to set the time on the clock when it is muted.
• When the button is pressed the Repeat: the hours, quarters and minutes on demand.

To ensure that this remarkable complication is not damaged should it be operated when too little power is available to the strike work, Audemars Piguet has developed both an indicator which shows the power-reserve remaining in the mainspring for the strike work, as well as a second indicator--called a Dynamograph---which indicates the curve of optimum torque which is ideal for the strike modes to be engaged for optimal performance. A small selector piece at the upper right hand corner also allows the watch to be set to "Silence" should the owner not desire the Sonnerie to sound. The craftsmanship which Audemars Piguet lavishes upon the movement of the Jules Audemars Grande Sonnerie Dynamograph watch is breathtaking, representing the finest in traditional haute de gamme techniques. Steel parts are individually drawn with a file, while bridges feature perlage on their bottom side, Cotes de Geneve on their topside, and anglage polishing on the edges. Screw and jewel settings are all countersunk and polished, while certain parts, such as the hammers of the striking mechanism display the luxurious specular polish. Purely functional components such as wheels and pinions are given no less careful scrutiny, resulting in a watch that is a true work of art in every respect.

Extremely limited in production, with only a few pieces produced each year, the Audemars Piguet Jules Audemars Grande Sonnerie Dynamograph watch presents its noble horlogical quality in an 18K white gold case. This graceful round case, a hallmark of all watches within the Jules Audemars Collection, features a sophisticated brushed finish, with highly polished elements on the bezel, and caselugs. The beautiful dial is a fine compliment to this classic, yet extremely complex timepiece, featuring a central section decorated with a Cotes de Geneve finish. A luxurious, remborded crocodile strap, complete with a white gold AP folding clasp completes this exceptional Audemars Piguet watch.

Audemars Piguet- Jumping Hour Minute Repeater

The hours sing out once more on the new Jules Audemars watch from Audemars Piguet. They also dance across the dial with its jumping display and elegant blued Arabic numerals. Combining two in-house specialities – the Minute Repeater and Jumping Hours – this marvel of precision and harmony perpetuates Audemars Piguet’s supreme expertise in the field of complicated watches. With its case and dial featuring a new take on classical styling, it gives a fresh boost to the Jules Audemars collection. This delightful new model will be music to the ears of connoisseurs the world over.

The Audemars Piguet Calibre 2907 driving the new Jules Audemars Jumping Hour Minute Repeater is clearly inspired by the movement of the historical 1992 model, whereas the architecture has been entirely redesigned to match the new case dimensions. Audemars Piguet has implemented innovative solutions to accommodate the relatively large movement and the complex striking mechanism within a diameter of just 43 mm. Blending traditional expertise and cutting-edge technologies, the Manufacture has also endowed the audible mechanism with all the fine-tuned technical details that distinguish its latest generation of Minute Repeaters. In particular, the movement has been equipped with a device that does eliminate any audible gap when the watch does not need to strike a quarter (e.g. 9:13); the sequence of 9 hours and 13 minutes is thus struck smoothly and without any interruption. Minute Repeater watches generally preclude any manual time-setting when the striking mechanism is in operation, since this might damage the movement. To remedy this problem, Audemars Piguet has developed a system that disengages the time-setting system while the watch is striking. This set of breakthrough developments thereby enhances the reliability, the security and the user-friendliness of Minute Repeater watches, while remaining true to the aesthetic appearance of the vintage models. The jumping hour mechanism has also been optimised. So as to enlarge the numerals while making sure the disc was not too large for the movement, watchmakers had to rethink the positioning of the disc and shift it towards the centre of the calibre.

20 pieces total will be made.
Case is 43mm and thickness 12mm.
