Jaeger-LeCoultre’s history is intimately tied to its peaceful and unspoiled surroundings in the Vallée de Joux, where the sounds of nature still prevail. The icy winters meant countless hours spent indoors, allowing the valley’s early watchmakers the time needed to develop and build complicated chiming watches. Although the structure of chiming watch mechanisms has remained essentially unchanged since the early 19th century, Jaeger-LeCoultre has constantly worked to improve both the mechanical efficiency of its movements and the clarity and beauty of the sound being produced.
