The eight of the planned 10 limited editions to mark Lange 1’s 25th Anniversary celebrations has been unveiled by A. Lange & Söhne. So after the release of emblematic Lange 1, Little Lange 1, the sublime Grand Lange 1 Moon Phase, the Lange 1 Time Zone, the phenomenal Tourbillon Perpetual Calendar, the Lange 1 Moon Phase and the Grand Lange 1, it’s now time to meet the Lange 1 Daymatic 25th Anniversary Edition.
The Daymatic was introduced in 2010 as the self-winding mirror image of the Lange 1. Identical yet different. At first sight, the 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 Daymatic with a retrograde day-of-week display on the opposite side. This is based on the realization 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 “25th Anniversary” edition has a white-gold case with a diameter of 39.5 millimeters and the same argenté-colored, recessed dial with blued steel hands seen on all the silver jubilee editions. 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-color concept.
It is powered by the self-winding L021.1 manufacture caliber. A large central rotor with a peripheral centrifugal mass in platinum efficiently ensures a power reserve of 50 hours. 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 Lange outsize date is engraved in the floral pattern filled with blue. This watch is limited to just 25 pieces and is priced at €44,200.
