The Harmony 4000S/000R-B123, seen from the bench
The Vacheron Constantin Harmony 4000S/000R-B123 is a 40mm rose gold case watch featuring a complete calendar complication with moonphase. The automatic Caliber 2460 QCL movement displays hours, minutes, seconds, date, day, month, and moon phase across the dial with a sapphire caseback. The 19mm lug width is specific to this tonneau-shaped case design. This model represents Vacheron Constantin's reinterpretation of 1920s wristwatch aesthetics within the Harmony collection.
