Preview of the Lange 1 Daymatic by A. Lange & Söhne which will be presented at SIHH 2010. The absolute novelty, compared to the hitherto manual versions of the Lange 1, is the use of a self-winding mechanical movement, calibre L021.1, with a central rotor (the previous automatic movement produced by Lange for the Langematik had an off-centre rotor). Another difference is the dial, which has a mirror-image design compared to the Lange 1: now the main hour and minute dial is on the right side, while the patented large date display has been moved to the left side. The Lange 1 Daymatic will be the protagonist of the cover of L'Orologio 184 (on newsstands at the end of January), inside which there will be a feature dedicated to almost all the novelties that the company will present at the forthcoming SIHH and an interview with Tony de Haas, Head of Product Development A. Lange & Söhne. For information: Richemont Italy, tel. 02/30261.
