A. Lange & Söhne Lange 1 Daymatic Yellow Gold Ref. 320.021

The Lange 1 Daymatic is a remarkable watch to observe. Although it looks familiar at first glance, it will soon seem like something is strangely different. And that's right: it's main (and familiar) indications are mirrored compared to other Lange 1 watches. In addition to the hours, minutes, small seconds and big date, caliber L02.1 also displays the day of the week through a hand on the 9:00 side. Ref. 320.021 has a yellow gold case.
