Literature
The Jaeger-LeCoultre Caliber 101 watch, launched in 1929, holds the title of the smallest mechanical watch in the world. The Caliber 101 measures only 14 mm in length, 4.8 mm in width, and weighs barely 1 gram, making it a feat of engineering and miniaturization. This movement has been used in high-precision jewelry watches, often adorned with precious stones, securing its iconic place in luxury watchmaking.

A famous example of the Caliber 101 is the watch worn by Queen Elizabeth II at her coronation in 1953. This miniature model remains a hallmark of Jaeger-LeCoultre for its highly sophisticated jewelry creations. The complexity of crafting these watches remains a challenge, even with modern technology, due to the extreme precision required to assemble such a tiny movement.
