Style Edit: Vacheron Constantin’s new Overseas Perpetual Calendar Ultra-Thin models

The Swiss watchmaker is famed for its complications and for the slimness of its timepieces – these 2 new models being a mere 8.1mm thick
Perpetual calendars are among the trickiest of horological complications to engineer. The reason: our logic-defying calendar. With the months varying in length, and a leap year coming along to throw a spanner in the works every four years, it’s fiendishly challenging for a mechanical movement to reliably keep up, navigating all that calendrical complexity to update itself accurately over years, decades and even centuries.

Backed by 270 years of watchmaking experience, Vacheron Constantin has long been a master of perpetual calendars – the venerable Swiss maison created its first such timepiece as long ago as the 1880s. It really moved the dial, though, with the introduction in 2016 of the Overseas Perpetual Calendar Ultra-Thin. It was a daringly slimline evolution of a collection that had first seen the light of day two decades before, characterised by a sporty yet smart aesthetic, with a powerful nod to Vacheron Constantin’s Maltese cross emblem in the form of its trademark notched bezel.
