The collection is now joined by a Malte Tourbillon Openworked model with an 18K 5N pink gold case. This new creation bearing the Hallmark of Geneva is a rare occurrence in the Fine Watchmaking world. Its curved 38 x 48.24 mm pink gold case frames an entirely openworked and hand-engraved barrel-shaped tourbillon movements. Alternating shadow and light effects enable Vacheron Constantin Caliber 2790 SQ to reveal an original architectural decor playing with geometrical shapes.
The resulting entirely hand-engraved three-dimensional mosaic is magnificently enhanced by an imposing Maltese cross-shaped tourbillon. Around 540 hours of patient, rigorous and accurate workmanship, from the development of the caliber to the manual finishing of each of its 246 components, are required to achieve the clever balance between a tourbillon mechanism and the aery openworked aesthetic. Coated in pink gold, this mechanism powering indications of the hours, minutes, seconds, date and power reserve, appears through a transparent sapphire dial rimmed by a silver-toned ring and punctuated by 11 baton-type hour-markers as well as an applied Roman (XII) numeral in 18K 5N pink gold.
