Can you give me any information about this Longines?
I know it's from 70s but not sure about that
and it is never worn up.
Thanks in advance

1970's model, as you surmised. the "20" refers to 20 microns of gold plating. The 508 movement is taken from a Record movement somewhat modified and rebadged as a Longines movement after Longines acquired Record.

Only thing to add is the reference number - 8452 as shown on the inside of the caseback.

Longines acquired Record.

..... in 1961. IIRC, the 50x series are rebadged 195x calibers.

I've got a Longines with a 50x series movement. It keeps excellent time.

It's not worth anywhere near that price. I'd find a new watchmaker.

If you like the watch then it’s worth it every cents. You not only buying a watch but you are buying some collectible piece and a history.
