Now, the Girard-Perregaux watch demonstrates a round case crafted in pink gold and measuring 41 mm in diameter. The case demonstrates proportions and curves to provide a perfect fit on the wrist.
The new Tourbillon with three gold Bridges boasts a rare shape for the bridges themselves, actually inspired by the bridges found on the watch that received the prize by the Neuchatel Observatory in 1860.
The bridges of the new watch are presented in an open-worked version. First of all, the bridges are hollowed out and meticulously hand-polished. The Girard-Perregaux master watchmakers require seven whole days to come up with an impeccable finish.
The sophisticated construction of the Tourbillon implies utmost attention to detail. The Tourbillon is constructed from 72 components, all of them fitting into a diameter of just one centimeter. The tourbillon weight is just 0.3 grams- its weight may be compared to a swan's feather. Girard-Perregaux received a patent for a self-winding system that represents an oscillating weight, small in diameter, crafted from platinum and fitted in the space below and around the barrel. The system allows to keep the dimensions and architecture of the movement intact. The 30-jewel movement, beating at a frequency of 21,600 vibrations per hour, provides 48 hours of power reserve.
The new Girard-Perregaux Tourbillon with three gold Bridges is limited to just 50 pieces.
The case-back of the watch is fastened with 6 screws. The timepiece is 30-meter water-resistant. It goes on an alligator leather strap fitted with a deployant buckle.
In the middle of the 19th century, watchmaker Constant Girard-Perregaux was engaged in researching the field of the Tourbillon escapement. In 1860, the watchmaker presented a timepiece that won a first-class prize by the Neuchatel Observatory. The Tourbillon movement of the timepiece amazed watch connoisseurs by three parallel bridges, with the barrel, centre wheel and Tourbillon aligned under them.
In 1884, Constant Girard-Perregaux applied for a patent from the United States Patent Office to provide protection to the movement designed with three parallel arrow-like bridges. The watchmaker introduced an absolutely new concept into the field of watchmaking - the movement was considered to represent not simply a technical and functional part of a timepiece - it was also a design feature. In 1889, the Tourbillon with three Gold Bridges received a gold medal at the Paris Universal Exhibition.
In the late 1970s, Girard-Perregaux resumed the production of the legendary Tourbillon. As Watches.InfoNIAC.com found out, the first sophisticated model appeared in 1981 as a series of twenty pocket watches. Since then, the brand has created a few rare watches every year.
