Planetarium Tri-Axial - defying gravity Tri-Axial tourbillon and astronomical moonphase display Terrestrial globe performs one full turn in 24 hours 48mm white gold case features two sapphire domes and a side opening Driven by the manufacture calibre GP09310-1038 HORLOGICAL INGENUITY AND EXPERTISE In the 1860s, Girard Perregaux transformed the world of watch making with a Tourbillon With Three Gold Bridges - taking bridges from a technical element to a visible, integral part of the timepiece. Today, it is known as one of the most distinctive and beautiful movements in watchmaking. A reinvention of an icon, the contemporary Bridges collection pushes the boundaries of timepieces for modern living, continuing a bold tradition of making the invisible visible. While the architecture and design codes from the original collection have been preserved, changes to the design of the bridges, shape of the crystal, and the heart of the calibre, have set a new standard in the world of horology. DEFYING GRAVITY One of the few triple-axis tourbillon in the industry, this exceptional, three dimensional Planetarium model defies gravity with a Tri-Axial tourbillon, astronomical moonphase, and a terrestrial globe performing one full turn in 24 hours to provide a view of time all across the world. The 48mm white gold case features two sapphire domes and a side opening, allowing the tourbillon to be viewed from all angles, while the calibre GP09310-1038 movement ensures precision and reliability with a 64-hour power reserve.
