Identical yet different. At first sight, the Lange 1 Daymatic looks like a typical Lange 1. Nonetheless, it differs from the manually wound original in a key aspect: its asymmetrical dial was mirrored. The hours and minutes have been shifted to the right, the subsidiary seconds and the outsize date to the left. The power-reserve indicator of the Lange 1, located adjacent to the crown, has been replaced in the Lange 1 Daymatic with a retrograde day-of-week display on the opposite side. This is based on the realisation that in a self-winding watch, the weekday information is more relevant than the current state of wind. Additionally, the day of-week display ideally complements the outsize date.

The special features of the Lange 1 Daymatic “25th Anniversary” include a white-gold case with a diameter of 39.5 millimetres and an argenté coloured, recessed dial with blued steel hands. The inscriptions, including the numerals of the Lange outsize date, echo the blue hue of the hands. A blue hand-stitched alligator leather strap with a solid white-gold buckle underscores the two-colour concept.

The self-winding L021.1 manufacture calibre has a maximum power reserve of 50 hours. A large central rotor with a peripheral centrifugal mass in platinum efficiently provides ample winding power. It rotates above the decorated movement and hence reveals Glashütte ribbing, perlage and other finishing techniques. Relying on a Lange balance spring, the indexless oscillation system is adjusted with six cams on the balance rim. The handengraved Lange-style balance cock of the “25th Anniversary” edition stands out with a special detail: set to 25, the iconic Lange outsize date is engraved in the floral pattern filled with blue.
