WATCHMAKER｜The Structure of Vacheron Constantin's Caliber 3500

This automatic winding movement, boasting a 51-hour power reserve, marks the first time Vacheron Constantin has incorporated an exceptional peripheral oscillating weight in its movement series. Mounted on ball bearings, this unconventional structure offers the Caliber 3500 a perfectly unobstructed view, entirely hand-decorated in accordance with the noblest watchmaking traditions.
