In 1936, Vacheron Constantin launched two other world timepieces, showing the regional time of 31 cities (model 3650) and 30 cities (except Cairo) (model 3638). In 1937 and 1938, the brand launched six table clocks. With a mobile dial design, the time can be displayed in 67 regions, including summer and winter time in Paris. From the 1940s, Vacheron Constantin introduced the world time clock with the model number 4414. The dial can display the time of 41 cities, and the 24-hour moving disc is divided into two areas: day and night. During the 1940s and 1950s, the brand made a name for itself with its superb achievements in this functional timepiece, making it a masterpiece for many celebrities to chase.
