A. Lange & Sohne Lange 1 Time Zone Watch

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. 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.

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.
