Jaeger-LeCoultre, the manufacturer of Atmos clocks, sells the clocks directly through Jaeger-LeCoultre.com. The website also provides a listing of retail outlets in North America that sell the clocks.
Jaeger-LeCoultre is based in Switzerland but has a Client Relations department and a Service Center that are based in the U.S. Points of sale for Atmos clocks in the U.S. include a number of Jaeger-LeCoultre Boutiques, as well as many retailers that are authorized Jaeger-LeCoultre dealers.
Jean-Leon Reutter designed the first Atmos clock in 1928. Early versions of the clocks are now collectible and may occasionally appear on auction sites such as eBay.
