In 2017, with the Lange 1 Moon Phase, A. Lange & Söhne took a new approach to depicting the moon phases by combining the eponymous astronomical display with a day/night indicator. To mark the occasion of the 25th anniversary of the Lange 1, it is now being presented in an exclusive 25-watch limited edition in white gold with blued steel hands.
