My latest arrival, due back from the workshop any day now. Can anyone give me an idea of the approximate date these were made. (pics to follow)

Dr. Ranfft's database lists the Landeron 54 as having been made from 1937-1970. Without seeing your watch, I can say that most of the chronographs I've seen labeled LePhare date from the post-WW2 period, up until the early 1950s.
