Jaeger-LeCoultre is a Swiss luxury watchmaker that was founded in 1833 by Antoine LeCoultre in the town of Le Sentier, Switzerland. The company has been responsible for many horological innovations, including the first watch with a millionometer in 1844, the first keyless watch in 1847, and the first watch with a perpetual calendar in 1879.
Jaeger-LeCoultre watches are known for their precision, durability, and intricate designs. The company produces a wide range of models, including dress watches, sports watches, and complicated watches with features like moon phase displays, tourbillons, and minute repeaters. The brand is also known for its Reverso line of watches, which feature a reversible case that allows wearers to protect the watch face by flipping it over.
They are highly sought after by collectors and connoisseurs of fine timepieces, and the brand has won numerous awards for its technical and aesthetic achievements. Some of the company's most famous models include the Reverso, the Master Control, and the Atmos clock, which is powered by changes in temperature and atmospheric pressure rather than a traditional winding mechanism.
