The Patrimony Contemporaine Ultra-Thin Calibre 1731, the latest minute repeater from Vacheron Constantin, took four years to develop and uses a movement based on the Calibre 1755 which was introduced in 1992.
The remarkably thin movement is just 3.90mm, just slightly thicker than the 1755, and is equipped with a 65-hour power reserve and unique silent flying-strike governor which ensures a steady cadence in the musical notes. It is named for the birth year of brand founder Jean-Marc Vacheron.
The Patrimony Contemporaine Ultra-Thin Calibre 1731 builds on the elegant and restrained aesthetic of the collection by adding subtle modern design cues, most notably, a small seconds at 8 o’clock and alternating baton and triangular hour markers. The 18k pink gold case is 41mm across and just 8.09mm thick. You can see the beautiful movement in action through the sapphire caseback, which is where this watch really shines.
As an homage to the artistry of the master watchmaker who makes each watch, every pieces features a subtle variation in sound – a permanent aural fingerprint registered in the Vacheron Constantin archives.
While there is no final pricing for the Patrimony Contemporaine Ultra-Thin Calibre 1731, it should come in at around 270,000 Euros with a scheduled yearly production of only 10 to 15 timepieces. For further details visit the Vacheron Constantin website.
