Hello. I am looking for some information regarding the history of the Longines Olympian models. I bought one at an auction and I would love to know more about this line. Also could someone tell me why some Longines of the 1970s don´t have the Longines logo on the dial but on the crown.
Thanks in advance

 

Welcome to the forum, most people here cannot think without pictures, they are very easy to upload.

 

I don't have the answer to the OP's inquiry, but coincidentally, my watchmaker has an Olympiam he serviced and has up for sale. I am interested in any information other informed members can provide.
And I come with quick and dirty pics...
