Two circles designate two time zones which are assigned to places
The large circle with numbers designates the home time on the A. Lange & Söhne Lange 1 time zone and the small inner circle the time of another time zone. All 24 time zones are present on the city ring with the name of a city. An arrow at 5 o'clock indicates the city or place that stands for the zone shown. The zone correction button allows each wearer to advance the city ring and zone time incrementally by 60 minutes. This corresponds to a journey around the world to the east.
The customer chooses between four variants of the time zone
Interested parties can choose between four models: The Long 1 Timezone "25th Anniversary", made of white gold and a dial in Argenté. Version two is made of platinum and the dial is in Rhodié. Number three is in white gold with an Argenté dial. The latest creation is the time zone in pink gold and the dial in Argenté. Walter Lange's motto can be summed up as follows: A watch and a person should never stop. Anyone who travels around the globe by plane a lot chooses an A. Lange & Söhne Lange 1 time zone.
