A. Lange & Söhne Lange I Little Mondphase Aventurin

The icon, the watch that relaunched the maison, and still its signature. When A. Lange & Söhne returned in 1994 after German reunification, the Lange 1 led the way, and its asymmetric dial has defined the brand ever since: an off-center hours and minutes, a small seconds, the outsize date (inspired by the five-minute clock at Dresden's Semper Opera House), and an Up/Down power-reserve indicator, all arranged so nothing overlaps. It's the most collected and recognizable Lange there is. If you want the essence of the brand, you start here.
