I'm pretty new to Longines. I own an early 40s tank which I like very much, but have taken a liking to the Longines Record models.
There are two I'm looking at- a 1950-60 (advertised) model with date (calibre 651) and a later 1960-70 without date (calibre 650).
Both look to be in similar condition, although the later (with bracelet) may be slightly better.
I've searched here (and in the vintage forum) and elsewhere but really can't find very much information at all on these models. Were the movements Longines or Record?
Can anyone give any advice or information on these, and perhaps which would be the better of the two? The early date model is the cheaper buy.
