The Vacheron Constantin Malte Openworked Tourbillon Platinum represents one of the finest expressions of traditional Genevan haute horlogerie. Combining a tonneau-shaped platinum case with the beautifully skeletonised in-house Calibre 2790 SQ, it showcases the extraordinary artistry required to transform a complex mechanical movement into a sculptural masterpiece without compromising reliability or performance. Bearing the prestigious Hallmark of Geneva, it is widely regarded as one of the most refined openworked tourbillons of the modern era.
The Malte Openworked Tourbillon Platinum is far more than a skeletonised watch—it is an architectural interpretation of fine watchmaking. Every bridge is meticulously hand-finished, bevelled and openworked to expose the movement’s intricate geometry while preserving structural rigidity. Unlike many skeleton watches designed primarily for aesthetics, the Calibre 2790 SQ was engineered from the outset as a shaped tonneau movement, allowing every component to follow the elegant contours of the case. Produced in extremely limited numbers and certified by the Hallmark of Geneva, it remains one of Vacheron Constantin’s most technically and artistically significant modern tourbillons.
