The release of 10, count ’em, 10 new references in the Vacheron Constantin Harmony collection gave us a chance to take a second look at the Harmony Chronograph – a flagship monopusher chronograph with an in-house movement, and some unusual and, we think, unique technical features. Most of the watches recently announced however have been essentially incrementally changed versions of existing watches. But there is one watch that is entirely new to the Harmony collection, and that’s the Harmony Complete Calendar.
