The original Saxonia model had Lange's patented big date mechanism, but this arguably unbalanced the dial. Even fans had to admit that these two large squares were out of place in a simple dress watch. For this reason, Lange removed the date complication for the 1995 "1815" model. The name of the watch refers to the birth of the brand's founder Ferdinand Adolph Lange, who was born was born in Dresden on 18 February 1815. The primary difference between the 1815 and Saxonia lines is that the former uses Arabic numerals while the latter uses baton markers.
This watch had a larger 35.9 mm case and used a new round movement, Cal. L941.1. The original yellow gold/silver dial “1815” Ref. 206.021 remained in production until 2008 and was joined from 2005 by the white gold/black dial Ref. 206.029.
1997 through 2008 also saw the "1815 Ab/Aus", which used Cal. L942.1 in a 35.9 mm case with small seconds at 4 00 and a power reserve display at 8 00. A similar watch was produced those last two years as the “Walter Lange” in a 37.5 mm case with a hinged back.
1999 through 2001 saw the limited edition "1815 Moonphase Emil Lange" produced, with a 36.9 mm case and moon phase indicator at 8 00, thanks to Cal. L943.1. The limited Ref. 212.050 "1815 Moonphase F.A. Lange Homage" of 2010 to 2013 has similar appearance but uses Cal. 943.2.
