Girard-Perregaux have unveiled the Tri-Axial Tourbillon at Haute Horology in La Chaux-De-Fonds, continuing their momentum from GPHG awarded Constant Escapement L.M.
This outstanding timepiece features a toubillon with three axes of rotation, all independent of each other, all suspended in a three dimensional sapphire crystal bubble that looms out of its' rose gold case.
The Tri-Axial Tourbillon features a 48mm pink-gold case, which houses a 317-component GP09300 caliber; which itself measures 16.83mm, mainly due to the tri-axial tourbillon mechanism's 13.78mmdiameter.
There is also a sapphire crystal featured on the side along with window on the caseband, functioning as further housing for the toubillon and allowing side viewing.
As the name suggests, there are three axis' of rotation, each in its' own cage. The outer cage rotates once every two minutes, the mid cage at 30 seconds and the center tourbillon is a one minute rotation. This is at a balance beating at 3 Hz (21,600 vph). The tourbillon itself only weighs 1.24 grams, composed of various materials, including rose gold, titanium and steel, each used for the correct strength and weight where neccessary.
The Tri-Axial features incredible finishing through out. Brushed and polished surfaces, hand-chamfering, mirror polishing and circular graining make this timepiece a joy to view at any angle. One can even view the manual movement through the sapphire back with no rotor obstructing the view.
The Tourbillon is found at 9 o'clock on the soft grey dial, which has darker grey areas surround the tourbillon, the actual time telling dial on the top right and the 52 hour power reserve indicator just below it.
