To celebrate the 10th anniversary of its Tokyo boutique in the popular Ginza shopping district, A. Lange & Söhne is releasing a limited edition version of the Lange 1 Daymatic. The Daymatic is exactly what it sounds like – it has the popular Lange 1 layout, only reversed and with a retrograde display for the day of the week where the power reserve would be on a basic Lange 1. Additionally, it’s automatic, with a full winding rotor visible on top of the movement and its three-quarter plate. What makes this white gold model unique is the guilloché dial, which is solid gold with an argente color treatment and blue accents on the hands and date display. This watch will only be available at the Ginza boutique and production is limited to 20 pieces.
