Watch to Watch for: Girard Perregaux Tourbillon With Three Gold Bridges

Girard Perregaux- “Mechanics of Time Since 1971”. Girard Perregaux is one of the few authentic Swiss watch manufactures. The watchmakers at GP design, create, develop, and produce both the external components of a watch, and its “heart”, the movement. GP has always been proud of its heritage, producing top of the line products for over two centuries. The GP Tourbillon with Three Gold Bridges is just the latest example of sucess GP has making watches. Shown off to excellent effect by a round case carved out of pink gold, its characteristic design symbolizes supreme harmony between art and technique. It is thus the perfect embodiment of an exceptional Haute Horlogerie timepiece.

It was first hand-crafted by Constant Girard-Perregaux back in 1860. Its mechanical movement is placed under three parallel arrow-shaped bridges.. This was a revolution in the history of Haute Horlogerie, imposing for the first time a watch’s mechanism as an element of design in its own right, beyond its technical function. The expression of a unique heritage whose origins can be traced back to the mid-19th century, this new version in pink gold is available in a strictly limited edition of only 50 pieces.

Contained within its diameter of 41 mm that adapts perfectly to the wrist, its three arrow-shaped bridges are extremely attractive. Creating the Tourbillon device takes an immense amount of attention to detail; its 72 component parts being meticulously assembled within a space only 12 mm in diameter. The upper and lower cages are hand-polished, as are the bridges, and the balance keeps its equilibrium thanks to gold regulating screws. Under the sapphire crystal with its anti-reflective treatment, the three bridges for a striking contrast with the color of the platinum. This specific timepiece is also available in a limited version of 18 pieces, set with 88 diamonds on the bezel, the case-center and the lugs (as seen in the picture above). The 50 piece plain edition costs $211,500. The more expensive edition covered in diamonds, limited to only 18 pieces, costs $406,500.
