The special edition version comes with a striking 18-carat honey gold case and features an uncluttered dial allowing for a single-glance reading of home time as well as the time in a second time zone.
The time zone is set with a lateral pusher, while it also advances the rotating city ring with the 24 place names from west to east. Furthermore, the anniversary edition also includes an additional detail on the rotating ring, where Dresden replaces Berlin to represent Central European Time.
Other notable features include the hour hand on the small subsidiary dial that moves forward with each actuation of the pusher. An innovative synchronisation mechanism makes it possible to transfer the zone time on the subsidiary dial to the main dial.
Only a hundred units of the watch have been created. Inside is the lavishly hand-finished manufacture calibre L031.1 which has a power reserve of three days.
The special edition Lange 1 Time Zone is available exclusively in A. Lange & Söhne boutiques worldwide.
