Patented in 1884, the three bridges movement is Constant Girard-Perregaux’s greatest contribution to the art of complicated watchmaking. A technical function that ended up being a design feature as well. This year watchmaker introduces a new three bridge watch that continues to exist and evolve 125 years after its introduction. The straight bridge design of the new Girard-Perregaux Tourbillon With Three Gold Bridges gets its inspiration from a Tourbillon with three nickel Bridges created by Constant Girard-Perregaux in 1860.
Housed in a 41mm case are three parallel Bridges, their arrow-shaped geometry design doesn’t allow room for any flaws as they would be revealed in the open worked main plate. The finishings on the hand-made bridges are so delicate, they can only be done by handful of experienced craftsmen in the watchmaking world. The “Mirror polish” finish of the bridges offers a fascinating contrast with the matt mainplate when the light slips in and reflects off. The perfect curves of the bridges were achieved by beveling them along their entire length.
The barrel drum at 12 o’clock is skeleton-crafted to reveal the workings of the artfully done platinum micro-rotor. A work of wonder is the tourbillon system with 72 components that weighs just .03 grams, they are methodically assembled into a microscopic 1cm diameter area. The cage and the gold adjustment screws of the watch are hand-polished and beveled like the escapement.
The Tourbillon With Three Gold Bridges gets it power from the in-house designed and assembled GP09600-0024 self-winding movement with a 48 hour power reserve and 3Hz frequency. Water resistant up to 100 ft, its case back is secured by 6 screws.
Available in pink gold and white gold versions, the watch comes fitted with an alligator strap in black with matching pin buckle in case color.
