Lange 1 Perpetual calendar

In its latest variant, the classic from the house of A. Lange & Söhne focusses entirely on the complication from which it takes its name. In the Lange 1 Perpetual Calendar the months are displayed on a peripheral ring around the dial, which switches forward once per month. The characteristic dial layout with its decentralized arrangement of the hour and minute hand and the two-digit date display in a golden frame has been adjusted to house all displays. The large date is positioned between 10 and 11 o'clock on the left side of the dial, while the moon-phase, time and day displays are arranged in the middle. The 41.9-millimeter case shines in warm 18k rose gold with a dark grey dial made of massive silver. The look of this elegant watch is rounded off by color-coordinated hands and hour markers and a reddish-brown leather strap.
