THE SPIRITUAL LEGACY OF LANGE POCKET WATCHES.

The LANGE 1 is a mechanical wristwatch without peer or precedent. It was introduced as the first Lange watch of the new era and horologically represents a culmination of what aficionados and connoisseurs of fine watches associate with the great A. Lange & Söhne heritage. In its heart beats the spiritual legacy of the historic pocket watches built by Lange.

Die LANGE 1

TRADITION AND INNOVATION UNITE IN THE LANGE 1.

With its patented | outsize date, however, it also aptly demonstrates how tradition and ingenuity can come together in style. This useful display, like the | five-minute digital clock in Dresden's Semper Opera that inspired it, improves the legibility of the date by about three orders of magnitude in comparison with conventional timepieces. The solid-silver dial, with its characteristic off-centre displays, indicates the hours, minutes, and seconds. Depending on the model, the hands are made of gold or | blued steel. The UP/DOWN power-reserve indicator provides information on the state of wind of the twin mainspring barrels which, when fully wound, offers a power reserve of three days.

PRECIOUS MATERIALS AS ICONS OF SUPERB WATCHMAKING ARTISTRY.

The LANGE 1 comes in 18-carat gold or platinum with a hand-stitched crocodile strap or, as an option, with an exquisite precious-metal bracelet. The matching gold or platinum clasp is engraved with the Lange signature; the embossed winding crown is solid gold. The sapphire-crystal caseback affords a mesmerising view of the unique Lange L901.0 movement.
