Vacheron Constantin Les Cabinotiers Temporis Duo Grand Complication Openface Watch
Vacheron Constantin's Les Cabinotiers department is dedicated to one-of-a-kind timepieces that push the boundaries of watchmaking. The Temporis Duo Grand Complication Openface is their latest such creation. The single-piece edition combines three highly complex complications: a single push-piece, two-hand split-seconds chronograph, a minute repeater, and a tourbillon regulator with a spherical hairspring. While these three had been previously combined in 2022's Calibre 2757 movement, this new model employs the 696-component 2757 S, which is decorated and hand-finished for display underneath the sapphire dial and caseback. With a 45mm 5N pink gold case and leather strap, it's an impressive display of horology.
