The sapphire crystal is of unprecedented size (42 mm in diameter) and provides a view on some details of the mechanism. The 48 members of his cage skeleton are intertwined with each other and the total weight of the mechanism is reduced to only 0.485 grams. This building, named in Cintre integrates the tourbillon chronograph complication despite the use of a large diameter wheel.

The gauge constructed exclusively for the manufacture Graham La Joux-Perret has come to light after four years of research and two patents. Overall, the engineering know-how has acted by removing the inherent weaknesses of the tourbillon. First of its fragility. The number of elements small, lightweight, and the double bridge provides stability and rigidity to the building. In Graham calls him “Tourbillon impact resistant.” To reduce the sensitivity of the device controller to the magnetism in the cage was made extensive use of special iron-free. Its exhaust vibrates at 28,800 vibrations per hour.

In Graham stressed that the end result is to offer a gentle and aesthetics as the tourbillon complication with the resistance of a military watch.

The details of that caliber La Joux-Perret has accustomed us are quality watches: even the smallest mechanical part was rhodium. The rotor is supported on ceramic bearings, and the column-wheel chronograph which controls the display elements alternating with shiny satin.
