====== A. Lange & Söhne calibres ======

[[A. Lange & Söhne]] is known as much for their high-quality in-house movements as for their finely finished watches. The names of Lange movements usually contain two digits for the year of their introduction, one digit for the numbered position of the movement in the series of movements developed in that year, and one decimal for their position in the family of that movement, counted from 0 (basic caliber). For example:

|[[Lange L901|Lange L901.0]]|**90**|**1**|**.0**|
| ::: |developed in [[1990]]|first movement development in 1990|first movement in the L901 family|
|[[Lange L043|Lange L043.5]]|**04**|**3**|**.5**|
| ::: |developed in [[2004]]|third movement development in 2004|fifth variant of the base caliber in the L043 family|
