Well I also got the information I wanted...
Dear Jimmy,
The LB collection started with the number 1. The watches were then numbered consecutively first 1-999 and then A1-999 and later B1-999.
The numbering followed without regard to the reference of the watch i.e. the number 2 and 3 are not the same reference. So your watch is the 431st “Louis Brandt” watch made and not the 431st example of its type.
Hopefully this clears things up for you. Should you require specific details about your watch please use the “Extract of the Archive” service on our website. The link for which can be found below.
