Lange 1

The A. Lange & Söhne Lange 1 reference 191.039 presents the marque's defining asymmetric dial architecture in an 38.5mm 18k white gold case. Its silver dial arranges the off-center time display, outsize date, and subsidiary seconds in the distinctive four-register layout that has come to define the Lange 1 line. Calibre L121.1 powers the watch, embodying the hand-finishing traditions of the Glashütte atelier.

The Lange 1 was introduced in 1994 as one of four references that marked A. Lange & Söhne's revival after German reunification, and its asymmetric dial immediately set a new standard for dress-watch layout. Reference 191.039, in 18k white gold with a silver dial, entered the collection in 2015 and continues in production, representing a considered evolution of the original concept. White gold lends the case a cooler, more restrained presence than yellow or rose gold variants, making it a favored choice among collectors who prefer understated formality. The Lange 1 line as a whole is widely regarded as one of the most consequential watch designs of the late twentieth century.
