    The Maestro GC 8.0 Squelette

    The gem-set collection

    The new Maestro 8.0 Squelette GC.8.0 Gem-Set Collection is a series of four limited-edition watches, based on the Maison’s first ultra-thin open-worked reference with micro-rotor architecture. This new model is themed around diamonds, and features 66 baguette-cut stones of the highest purity set by hand into an 18-carat white gold bezel by specialist gem-setter Salanitro Geneve. The case is in medical grade stainless steel, while the vulcanised rubber strap matches the colour of the precious gem.

    Handcrafted Timepiece

    An important milestone for the Maison

    This piece in limited-edition series is the result of complex engineering solutions and savoir-faire applied to high-end watchmaking. Undergoing an extremely complex process, large baguette-cut gems are integrated by hand into the Maestro’s unique case architecture. Only 10 of each color in the exclusive series will be produced, making this timepiece among the most exclusive watches ever released by the Swiss Maison.

    Two years of research and development

    Hand drawn, hand crafted

    This timepiece is powered by the open-worked GCA8.0 calibre with micro-rotor architecture, an exceptional movement developed by the world-renowned designer Mr. Octavio Garcia. Gerald Charles and Mr. Octavio Garcia worked on the calibre in collaboration with Vaucher Manufacture Fleurier. The calibre, which took two years to develop, represents the Maison’s highest technical achievement in terms of movement architecture. When it came to designing the GCA8.0 calibre, Mr. Octavio Garcia chose the theme of the celestial sky chart. For example, the star-shaped cage that holds the micro-rotor in place is shaped like a shooting star, with rays spreading playfully across it.

    The Maestro GC 8.0 Squelette

    On the dial side, the Maestro 8.0 Squelette features some satin-finished and rhodium plated open-worked bridges; some others are treated with anthracite NAC. All angles, bevels and apertures are diamond-cut and hand-polished, and the yellowgold wheels are decorated with circular graining, a traditional high-end watchmaking finish. The rehaut features white painted minute markers and hands filled with highly luminous Super-LumiNova®. It is held in place by a series of nine star-shaped screws designed and developed by the Maison, while the open-working has been acutely considered so that the wearer will always get a glimpse of the 22-carat rose-gold micro-rotor through the dial. The micro-rotor features its sunray-brushed decoration on the dial side, while the view from the reverse is intentionally more subtle, with its sandblasted and brushed finish. All this is visible through the watch’s sapphire case back, as is the balance wheel at 7 o’clock, which is also visible from the dial side through the bridge openings.
