A. Lange & Söhne Lange 1 Daymatic “25th Anniversary” (Specifications and Price)
The A. Lange & Söhne Lange 1 Daymatic was introduced in 2010 as the self-winding mirror image of the Lange 1 that celebrates its 25th anniversary this year. Featuring a retrograde day-of-week display, this white-gold model with blue accents belongs to the ten- timepiece anniversary collection that comes in limited editions of just 25 watches.
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 hand-engraved 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.
