The Lange 1 Time Zone displays the local time at any given place in the world while faithfully keeping track of home time as well. Crafted with consummate perfection, it is a worthy global ambassador for the values behind the watchmaking artistry of A. Lange & Sohne. The Lange 1 Time Zone is a mechanical timepiece of global stature. It not only tells home time but also indicates the local time for any place on the face of the earth. On the solid-silver dial of this masterpiece, the gold hands of the main dial permanently display home time. The wheel train of the main dial is coupled with the patented, easily legible outsize date: it shows the date at home. The smaller dial with Arabic numerals can be set to display the local time in any of the world's 24 time zones. The gold arrow applied at 5 o'clock points at a city on the rotating city ring. It represents the zone whose time is currently being displayed on the smaller dial. The city ring can be advanced zone by zone by pressing the time-zone push piece at 8 o'clock. Concurrently, the hour hand of the zone-time dial advances as well so that at the end of the setting process, the small dial indicates the local time in the selected time zone. As a most useful feature, both dials of the Lange 1 Time Zone have separate day/night indications. And since time often flies on journeys, the watch also has an up and down power-reserve display that reminds the owner when it needs to be wound. The case of the Lange 1 Time Zone is made of precious platinum or 18-carat gold. It is worn on a hand-stitched | crocodile strap with a precious-metal buckle on which the Lange signature is engraved. The embossed winding crown is solid gold. The sapphire-crystal caseback of the watch reveals the fascinating inner life of this mechanical marvel.
