In 1860, Edouard Heuer started designing timepieces in Saint-Imier, Switzerland at the age of 20. The crown-operated, keyless winding system was his first patent, which changed the course of watchmaking history. Continuing his pioneering legacy, the Swiss luxury brand has gone on to introduce numerous innovative patents and timeless designs, deeming it one of the most advanced and luxurious watchmakers in the world.
