About the Lange 1 family
The Lange 1 was part of the brand's first modern collection of 1994. Its asymmetric dial places hours and minutes off centre, with a small seconds, the outsize date in a double window and a power reserve indicator, a layout based on the golden ratio.
The family includes the Lange 1 Time Zone, Lange 1 Moon Phase, Grande Lange 1, Little Lange 1, the automatic Lange 1 Daymatic and tourbillon and perpetual calendar versions. In 2015 the core model received a new caliber, the L121.1. Dealers identify the variant, size and metal and check the dial, which comes in several colours and finishes.
