Shop window clock:
Jewellers often placed clocks in their shop windows. This was not only meant for advertising the clocks but also provided a service for the public in a time when the exact time of the day was not always readily available. That is why shop window clocks were always precision clocks. As fas as we know there are only two shop window clocks produced by A. Lange & Söhne in Glashuette.
