Crafted in titanium so as to chime with greater intensity, this model powered by a mechanical manual-winding caliber houses two of the most challenging horological complications: the minute repeater and the tourbillon simultaneously gravitating around three axes.
In order to give the sound its full amplitude, the 48 mm-diameter case with its contemporary design is machined from grade 5 titanium. This metal was chosen because in this configuration and based on a number of studies conducted in the watchmaking workshops the algebraic ratio between the size of the (preferably large) case middle and the density (ideally as low as possible) is extremely favorable to acoustic expansion.
Playing the time
To visually highlight the operation of the hammers, the hour and quarter racks, as well as the surprise-piece enabling the mechanism to strike the minutes, the designers asked the watchmakers to create an original hours display structure allowing them to dispense with a dial. To free up as much space as possible and thus enable the repeater mechanism to reign supreme over half of the upper disc surface normally occupied by the dial, the watchmakers divided the space into two parts by means of a long bridge positioned in line with the winding crown.
Technical Specifications:
The case, in titanium, measures 48mm x 21.3mm. It has an AR-coated box sapphire crystal, a box sapphire display back, and it is water resistant to 30 meters.
Movement is the Swiss manual-wind Girard-Perregaux in-house caliber GP09560 with 53 jewels, 21,600 vph and a power reserve of 60 hours. Functions are: Tri-axial tourbillon, minute repeater, hours, minutes.
The dial has counters at 9 and 3 o'clock displaying respectively the hours and minutes thanks to two sapphire rings. Dauphine type skeletonized hands.
It comes on a hand-stitched black alligator leather strap with a triple folding titanium buckle.
