A Technological and Aesthetic Masterpiece in Haute Horlogerie
Vacheron Constantin continues to push the boundaries of fine watchmaking with the launch of its most technically ambitious Overseas timepiece yet — the Overseas Grand Complication Openface. Fusing complex horology with a bold, contemporary design, this extraordinary new model is the first minute repeater in the sporty Overseas collection and a testament to the Maison’s commitment to both innovation and tradition. Crafted in titanium and water-resistant, it seamlessly integrates a minute repeater, a tourbillon, a perpetual calendar, and a power reserve indicator, all within a remarkably slender movement just 7.9 mm thick.


At the heart of the watch lies Calibre 2755 QP, one of Vacheron Constantin’s most emblematic movements. Derived from the calibre that powered the legendary Tour de l’Île watch, this mechanism comprises 602 components and masterfully combines three of horology’s most prestigious complications. Its perpetual calendar requires no adjustment until 2100, and the minute repeater features a centripetal regulator that ensures clear, rhythmic chimes by controlling the striking sequence with precision and complete silence. Every element, including the hammers and bridges, has been painstakingly hand-finished and decorated — a testament to the Maison’s dedication to traditional craftsmanship.
Visually, the Openface lives up to its name. A transparent sapphire crystal dial reveals the intricate workings of the calibre below, bringing depth, movement, and modernity to the forefront. The floating white gold hour markers, contrasted against grey NAC-treated bridges and rhodium-plated wheels, give the watch a space-age elegance. Further enhancing legibility and visual drama, the sub-dials are framed with blue metallised rings, each engraved in white to display the various calendar and timekeeping functions. The effect is nothing short of hypnotic — a mechanical ballet visible on both the front and reverse of the timepiece.

The case and integrated bracelet are crafted from grade 5 titanium, known for its durability and lightweight properties. At 44.5 mm in diameter and 13.1 mm thick, the case maintains the iconic curves and proportions of the Overseas line while accommodating the mechanical complexity within. A meticulous blend of polishing, satin-brushing, and sandblasting creates a refined, tactile finish that changes with the light. The watch also includes interchangeable blue alligator leather and rubber straps, adding to its versatile, travel-ready appeal.
According to Christian Selmoni, Vacheron Constantin’s Director of Style and Heritage, the openface concept is deeply rooted in the brand’s history, dating back to the 1920s. “The kinetic, avant-garde aesthetic of openface designs demands an extra level of complexity,” Selmoni explains. “It’s about showcasing the inner beauty of the movement not just from the back, but from the front, and doing so in a way that enhances functionality and elegance.” He also emphasizes that a grand complication model like this belongs in the Overseas collection, proving that high horology can coexist with sporty utility and everyday versatility.

In sum, the Overseas Grand Complication Openface is a declaration of watchmaking excellence — blending Vacheron Constantin’s most refined complications with the daring, contemporary design language of the Overseas collection. It is as much a triumph of engineering as it is a work of art, destined for connoisseurs who appreciate the rare harmony of form, function, and fearless innovation.
