In these older Kieninger movements, the two-digit number before the letter K actually represents the year of manufacture; K designates the movement family and, for example, 116 cm the pendulum length.
However: For later movements, the first number sometimes became an internal movement/design code and can no longer be used as a year. Therefore, one should not automatically interpret a stamping like 01 K ... as 2001.
In addition, there are other Kieninger codes, such as KSU 33, HTU 06, RSU 12 or MSU 47, for which the numbers must be interpreted differently.
