Vacheron Constantin has introduced the Les Cabinotiers Temporis Duo Grand Complication Openface, a unique timepiece created by its Les Cabinotiers division. This one-off model incorporates a minute repeater, a split-seconds chronograph, and a tourbillon with a spherical hairspring.
The 45mm case is crafted from solid 5N pink gold, featuring sapphire crystals on the bezel and case back. The open-face layout features a 0.5mm sapphire dial with a polished surface, with frosted register tracks and contrasting 5N gold accents. Touches of green on the dial and hands echo the green alligator strap, which is secured by a 5N pink gold folding clasp that is shaped like Vacheron Constantin’s Maltese Cross emblem.
Inside, the manually wound Vacheron Constantin’s Caliber 2757 S consists of 696 components and operates at 2.5 Hz, offering a power reserve of 58 hours. The movement uses two column wheels, with aluminum hands and silicon components to optimize performance. Timekeeping is regulated by a spherical hairspring inside a one-minute tourbillon. A power reserve indicator is present on the reverse side of the structure, visible through the transparent caseback.
The watch bears the Geneva Seal and features a ‘JMV’ engraving on the bridge, a reference to the brand’s founder, Jean-Marc Vacheron.
The Vacheron Constantin Les Cabinotiers Temporis Duo Grand Complication Openface is a one-of-a-kind timepiece that is not available to the public. It is simply a demonstration of Vacheron Constantin’s watchmaking capabilities and commitment to custom watchmaking. For more information, visit the brand’s website.
