Esmeralda Tourbillon Tourbillon Watch

To celebrate the 225th anniversary of the brand, GP Girard-Perregaux has launched the rose gold Esmeralda Tourbillon tourbillon watch, continuing the legend of the three-gold bridge tourbillon pocket watch that won the gold medal at the Paris Universal Exposition in 1889. This exquisite and extraordinary mechanical watch perfectly reflects the brand’s pursuit of precise aesthetics.

   Since the establishment of Girard-Perregaux, GP has been famous in the international watch industry for its innovations and technological innovations. The unique aesthetics of watches combined with complex watchmaking processes have made Girard-Perregaux unique.

Three Golden Bridge Tourbillon-a symbol of the brand’s exquisite watchmaking skills
   Since the establishment of Girard-Perregaux GP, and the successful development of the first three-gold bridge tourbillon in 1860, Constant Girard has been dedicated to crafting the watchmaking skills of the brand. With the unique structure of the legendary movement design, he successfully reversed the traditional concept of the mechanical movement, successfully installed all the complex components, and added the aesthetic characteristics of a tourbillon watch that was only a mechanical movement. . In 1867, with its minimalist structure, this tourbillon with a three-gold bridge structure was shortlisted in Neuchâtel and won the first watch award for the brand. After obtaining a patent for this structure in 1884, Girard-Perregaux successfully developed a beautiful奂 Three Golden Bridge Tourbillon.

   The structure of this watch is the most forward-thinking initiative in the contemporary era, enabling pocket watches to successfully incorporate tourbillons, slewing brakes and three golden bridges. It was born at the 1889 Paris Universal Exposition and won gold prizes in the watch industry. Its exquisite case was carved by the then top art master Fritz Kundert. The name ‘La Esmeralda’ was taken from the names of Hauser, Zivy & Cie in Paris and Mexico. This pocket watch was later used by the time. Was purchased by General Mexican President Portirio Diaz (later President of Mexico), and details of the transaction remain unknown.

   The craftsmanship of this pocket watch is a contemporary example. It has set a new milestone in the watchmaking industry with an amazing balance. Under the hood, this watch returned to the Girard Perregaux Museum in 1970. With its exquisite design aesthetics, the Sanjinqiao Tourbillon has become the oldest movement in watchmaking history and is still used today. Its structure has been in use since 1860.

The proud quality of Sanjinqiao Tourbillon
   The minimalist aesthetics of the Sanjinqiao Tourbillon movement coincide with the essence of fine watchmaking aesthetics. Its structure matches the principle of the golden ratio and is entirely handmade by watchmakers. The components are processed and decorated by professional craftsmen, which is an exquisite masterpiece of art.
   The main board is made of pure gold bar splint, gear train bridge and tourbillon splint, which perfectly combines the ultimate aesthetics, technical essence and symbolic principles. The double-headed arrow design with hand decoration embodies the original aesthetics of Esmeralda Golden Bridge. The arrow surface adds a crystal effect, and the chamfered edges and the sides are manually processed and drawn. In order to enhance the visual contrast and brightness, the bridge arms are carefully ‘polished’, which means that they are rounded by hand with a polisher. In such a precise structure, the three bridges are side by side, creating a unique visual effect.

   The diamond polished structure in the middle of the three bridges is fixed with two screws, so the position of the splint, middle wheel and tourbillon shell must be exactly matched. The tourbillon housing has up to 80 components, all assembled by hand by very skilled craftsmen. The well-known hand-polished lyre of the brand makes the balance of the whole structure more perfect. It achieves an accuracy of 21,600 vibrations (3 Hz) per hour and a balance wheel, and is benefited by large moments of inertia.
   The volume of this movement is 16 legal minutes (36.60 mm in diameter) and 8.41 mm thick. It takes at least two months to assemble 310 components, including 27 gems.
   The three-point structure of the motherboard is obvious. All components-including the exposed golden bridge, multiple bridge arms and tourbillon housing-convey a message: the number ‘three’ and its plural, symbolizing past, present and future measurements.

Esmeralda Tourbillon Center of Tourbillon
   Following the 27 tourbillons registered by GP Girard-Perregaux at the Neuchatel Observatory between 1865 and 1911, the latest Esmeralda Tourbillon tourbillon tells a story of a passion for aesthetics and precision watchmaking.
   The 18K rose gold case has a diameter of 44 mm and is equipped with a self-winding three-gold bridge tourbillon mechanical movement. This 16-leg calibre ‘GP09400’ is entirely developed by the brand and occupies the entire ring, and is specially equipped with a tourbillon case with a diameter of 14.3 mm and a balance wheel with a diameter of 10.5 mm.
   Following the same aesthetics, this one-way automatic winding system developed by Girard-Perregaux breaks the tradition with its rotor under the splint, not outside.
   Thanks to the original structure, the watchmaker successfully enlarged the diameter of the spring barrel, so that he could extend the spring and increase the watch’s power reserve to at least 60 hours, far more than the previous 48 hours.
   The tourbillon watch has exquisite lines and the shape of the lyre is also based on the prototype originally designed by Constant Girard-Perregaux. This great masterpiece is inspired by one of the most iconic designs in the history of home-made watches, reflecting the fusion of tradition and modernity; with a black alligator strap and rose gold triple buckle.
