1815 RATTRAPANTE PERPETUAL CALENDAR HANDWERKSKUNST

Under the auspices of the lunar goddess

The star motif of the dial is echoed by the movement decorations: in the tremblage and relief engravings on the rattrapante cock, the balance cock, the chronograph and switching lever bridges and on the cover plate. The surface of the wheel train in German silver has a delicately granular texture inspired by the movements of historic pocket watches.

In its sixth HANDWERKSKUNST model, A. Lange & Söhne combines enamel and engraving on the dial for the first time. A relief engraving of Luna, the goddess of the moon in Roman mythology, graces the hinged cuvette of the 1815 RATTRAPANTE PERPETUAL CALENDAR HANDWERKSKUNST presented in 2017 in a limited edition of 20 watches. She can be recognised by a gossamer veil, a crescent diadem and a torch. On the dial, stars under the deep-blue ename, also relief-engraved, appear to be an extension of the moon-phase display.
