Vacheron Constantin Traditionnelle 14-day Tourbillon, Tokyo Boutique Edition

Issued in a three-piece limited edition, the Traditionnelle 14-day tourbillon appears clothed in black to celebrate the inauguration of Vacheron Constantin’s first Boutique in Japan.

Crafted in a three-piece limited edition for the inauguration of the Tokyo Boutique, this 18K 5N pink gold timepiece stands out by its finely hand-guilloché black dial bearing the “LIMITED EDITION TOKYO” secret signature at 12 o’clock. A magnificent tribute to the expertise acquired by the world’s oldest watch Manufacture having enjoyed uninterrupted activity since 1755.

While the first tourbillon appeared in 1801, the in-house development and production of this
horological complication remain the exclusive sphere of a mere handful of manufacturers. In this instance, associating the prestigious function with an impressive 14-day power reserve called for a dedicated construction. A “dragging” or “trailing” hand on the dial displays the remaining energy on a 280° sector.

This surface area, which is larger than on conventional indicators, enables a precise division of the 14 days, themselves divided into 12-hour slices and thus enhancing the legibility of the power reserve. The hour and minute indications are slightly offset in order to leave space for the tourbillon carriage. To guarantee the 14-day power reserve, the Vacheron Constantin mechanical manual-winding Calibre 2260 is equipped with four barrels stacked in pairs, interconnected and discharging simultaneously, yet four times slower than a single barrel.

The structure of Calibre 2260 with its 231 parts comprises two large bridges, whose generous dimensions provide magnificent scope for expressing the exquisite movement finishing and notably the Côtes de Genève motif. The tourbillon carriage, inspired by the Maltese cross, represents an exceptional showcase in terms of the high degree of finishing on the parts featuring a number of naturally hand-bevelled interior angles. The tourbillon bar alone took 11 hours of hand craftsmanship to round off.

The Traditionnelle 14-day tourbillon is loyal to the aesthetic codes that have forged the reputation of  this line imbued with a sense of tradition and rigorous principles: a slender case, a fluted case middle, applied facetted hands and “dauphine” hands. A screw-down sapphire caseback provides a chance to admire Calibre 2260, while a black dial that is finely hand-guilloché – expressing one of the unique skills cultivated by the Maison – sets the perfect finishing touch to this exceptional watch.

The master guillocheur has succeeded in combining straight and curved lines in order to create a unique sunburst pattern inspired by the Japanese “Rising Sun”. This array of elements contributes to identifying this refined and technical collection and serves as a reminder that tradition and modernity go hand in hand at Vacheron Constantin just as they do in Japanese culture.

From the mechanism to the exterior, everything about this new creation from Vacheron Constantin epitomises perfect execution, including its prestigious Hallmark of Geneva certification – the highest Haute Horlogerie benchmark testifying to the quality, the fine workmanship and the reliability of an exceptional timepiece crafted in Geneva.
