The present wristwatch is from the limited series of the "1815 Kalenderwoche" made in 2006 to commemorate the 150th anniversary of Uhren Huber in Munich. A combined total of only 150 examples were made, comprising 50 watches each cased in yellow and pink gold and in platinum.
The 1815 model pays tribute to the company's founder Ferdinand A. Lange, marking his birth year. The specialty of the 1815 Kalenderwoche, or calendar week, is that the wearer can have the full year in an overview as the watch shows the weeks of a year.
