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.
