The Maestro.99 Squelette Tourbillon Chronograph represents the ultimate masterpiece of Gerald Charles heritage. As the artistic testament of the Maison’s founder.

The squared carré case in pure Palladium is shaped as an asymmetric polygon with eight cut edges coins coupés and a hemispheric convexity, half-moon, at 6 o-clock. At first sight it resembles an Octagonal shape, yet surpassing it. The Maestro introduces an innovative, never seen, yet incredible case by the same creator of the first Nautilus* and Royal Oak*.

Chrono Tourbillon

This watch was conceived to host the most daring complications. The half-moon at 6 o’ clock creates a dedicated space for the flying Tourbillon, perfectly integrating mechanics and aesthetics.

In the pursuit of perfection the tourbillon ball is suspended between two sapphire crystals without any bearing bridge, highlighting the ‘Ballet’ of movements. The integrated chronograph on a skeleton movement is altogether a powerful combination. The Maestro.99 was produced in a limited edition of 12 pieces only. It is now preserved in the Maison’s private collection.
