Last year, Girard-Perregaux followed up on their GPHG-winning Constant Force LM with the dramatic Tri-Axial Tourbillon in red gold. The watch is a tour-de-force of complexity, housing a 140-component tourbillon that rotates around three distinct axes, each at a different speed. This year, Girard-Perregaux has updated the watch with a case made of white gold, and a more revealing dial design. We’ve got all the details and even a few exclusive images of the watch itself.

Girard-Perregaux’s Tri-Axial Tourbillon is unique in its finishing and its construction. The interior carriage, housing the escapement and balance wheel, is lyre shaped in typical GP fashion, and makes a full rotation every 60 seconds. This interior carriage is fitted into a separate structure that rotates around a separate axis every 30 seconds. Lastly, the structure as a whole rotates around a third axis, making a full revolution every two minutes. Having a difficult time imagining all that? We’ve got a video of last year’s model in action below.

The tourbillon assembly is fitted into its own bubble within the dial at the 9 o’clock position. It’s size and rotation requires additional clearance, so a convex lens been fitted into the sapphire crystal. The movement of the tourbillon is visible from the dial side, the movement side, and even through a sapphire window set into the wall of the case at 9 o’clock. This, plus the lack of cages used in assembling the tourbillon, make for optimal observing conditions of the balance wheel itself.

New for 2015 is the white-gold case, sized at 48 mm in diameter, and 16.83 mm in thickness. The robust dimensions are required to house the 317-component movement, the GP09300-0002. The Tri-Axial Tourbillon in white gold enjoys a revised dial design, featuring open slots to view the topside of the movement. Additionally, the hour and minute subdial has been redesigned with more traditional approach, now sporting minute demarcations and a sunburst pattern.

The Girard-Perregaux Tri-Axial Tourbillon is limited to 10 pieces. We’ll be going hands on with this watch this week at SIHH in Geneva, and will be updating with live pics and pricing details. More from GP here.
