I am trying to obtain some info regarding this watch and would love some help. I believe it is a 1962 La Petite B. The case is 10k white rolled gold and the dial has the letter B on it. There are two diamonds on the case, and it has a Speidel band pat. 2689450. It has a slight scratch on the lense and is not currently running. I am uncertain about the movement model . It is a gorgeous watch and I would love any information that can be provided about this particular model etc. thank you!
Hi Katie - it is not uncommon to have a movement and case date off by a year. Imagine the case being made on January 3 but the movement was assembled on December 30. Four days becomes a year older. In these cases we always date to the newest of the two as the watch could not have been made before the case was made. When the difference is two or more years we suspect the movement was swapped later in life and perhaps not original to the case.
