You may not know Jaeger-LeCoultre like you think you do.

Though recognized for its iconic Reverso timepiece and various important tool watches from the mid-20th century, JLC also holds the distinction of having developed the world’s smallest mechanical movement — a record that remains unbroken today. The Calibre 101, which debuted in 1929, was designed to power ladies’ cocktail watches — the type of pieces that combined the finest watchmaking with high jewelry in pieces that could be worn to dinners, balls, galas and the like. When found in good condition today, such pieces continue to dazzle. 

This particular ladies’ cocktail watch dates to the 1950s and features a 25mm 18K yellow gold integrated case and bracelet, an acrylic crystal, a signed JLC crown, a diamond bezel, and a silver satin dial with black stick hands and baton indices. In excellent condition and powered by a manually wound JLC movement, it’s a piece of horological art that looks as fashionable today as it did in the mid-20th century.
