The Lange 1, ref 101.027, with the blue dial, was firstly introduced in 1997. Being one of the very first watches made following the reconstruction of A. Lange & Söhne the watch can be considered a work of modern horology. The dial is formed from solid silver and adorned with solid-gold appliques and hour markers, its simple yet elegant and individual design elevates the interest and attention of even the most conservative collectors.The Lange 1, has a white gold 38.5mm case and, has all the traditional features of the model such as applied roman numerals and large double-window date. Remarkably, blue dials have not been a trend until approximately five or six years ago, however in the mid 90's Lange visionary horological department experimented with this colour to produce the dial you see today on this historically important Lange 101.027.
