Girard-Perregaux Cosmos unique pieces

First released in 2019, the Cosmos wonderfully demonstrates Girard-Perregaux’s horological prowess.  Equipped with three exceptional complications, the model encompasses technical virtuosity, uncompromising finishing and artisanal craftsmanship. Now, Girard-Perregaux has chosen to create three unique versions of this model featuring aventurine, obsidian and onyx, and, lastly, a combination of spectrolite and aventurine. These three models are the final edition of the Cosmos model and serve as a fitting swansong for this exceptional watch.

The Cosmos is equipped with three complications, including a tourbillon, a mechanism designed to counter the adverse influence of gravity on the regulating organ. Presented at the base of the dial, the tourbillon features a titanium lyre-shaped cage. This is held in position by Girard-Perregaux’s signature Neo Bridge, a contemporary interpretation of Constant-Girard’s famous ‘arrow-shaped’ bridge of the 19th century. 

Complementing the tourbillon, the watch is equipped with two additional complications, a terrestrial globe and a celestial globe. The terrestrial globe, located at 3 o’clock, serves as a day/night indicator. Positioned opposite, at 9 o’clock, a celestial globe displays the constellations of the Zodiac. All three unique pieces feature two-part dials, formed of aventurine, obsidian or spectrolite. Likewise, the globes are made of black aventurine, black aventurine or onyx. Each set of globes is endued with golden micro-painting, painstakingly executed by hand, a process that takes no less than 14 hours to complete.

The Sun revolves around the Earth every 24 hours, the time it takes for the terrestrial globe to rotate 360°. Celestial time equals the rotation period of a celestial object, namely 23 hours and 56 minutes. The different pace of each globe is barely perceptible to the human eye, however, Girard Perregaux has ensured that both globes rotate at the correct speed, demonstrating its unrelenting attention to detail. Unlike the real world, viewing constellations on the dial of this model is not impeded by light pollution or limited light.

A notable characteristic of the Cosmos is that the dial elements are arranged with due consideration to symmetry. The resultant dial layout is balanced and cohesive. Eager to augment this sense of balance, Girard-Perregaux has dispensed with a conventional crown. Instead, an innovative winding and setting system is located on the reverse of the timepiece emulating the styling of pocket watches from yesteryear. The setting system features three engravings, all of which are filled with luminescent ceramic, indicating the purpose of each bélière.

 

 

 

In contrast to the flat sapphire crystal to the rear, the front of the watch is endowed with a sapphire anti-reflective ‘box’, providing a three-dimensional view of the dial area. Its domed shape requires four to five times more material to shape and polish.
