It’s not just the LCD or general TV industry where extreme slenderness represents an indication for top-notch engineering expertise, it’s also in the horological market a sign for refined craftsmanship that often pushes micromechanical boundaries to the limit. The fine watchmaker Vacheron Constantin knows to profile itself on that certain expertise with claiming the world’s thinnest wristwatches for, soon, the 55th year. Vacheron Constantin has chosen this anniversary, in 2010, the time to re-issue two of their legendary micromechanical masterpieces to celebrate that highly decorated history. The square-shaped ‘Historique Ultra-fine 1968′ featuring a rebuilt ultra-thin self-winding Calibre 1120, now equipped with an 18-carat gold oscillating weight bearing the Maltese Cross system, and the ‘Historique Ultra-fine 1955′ featuring a redesigned version of the mechanical hand-wound 1003 movement that has already gained the record for being the “world’s smallest mechanical movement on the market” with just being a mere 1.64mm thick. Alongside the seductive slender silhouettes of the two, they both are stamped with the Hallmark of Geneva and feature a Côtes de Genève finish – the purest form of class and elegance re-issued for any horological enthusiasts.
