Vacheron Constantin revealed its most complicated watch featuring 57 complications, which was built in total secrecy, in 2016. A year later, they’ve released yet another, similarly built in secrecy (even within departments) and the most complicated yet, the Les Cabinotiers Celestia Astronomical Grand Complications 3600, with 23 complications. The watch’s development took 5 years and was sold at a whopping $1 million. No other company allows such amount freedom and time allowed to an unnamed master watchmaker.
According to Christian Selmoni, Vacheron Constantin’s artistic director, “This timepiece was created in the spirit of the historical astronomical clocks with extraordinary levels of precision, and that makes the Celestia very important.” The unnamed master watchmaker explained watchmaking and astronomy are interdependent as our ancestors learned to measure time watching the movement of stars, the moon, and the sun. The mathematical feat that the Celestia is would have been enormously more challenging without the computational help from the modern computers.
