I bought this Longine about 10 years ago. Not sure what model and estimate it is from the 60's. Any opinions would be welcome. The bracelet is a gold filled vintage that I think matches the watch well.

 

It sure is a 60's model. The fonts, hands, and lack of a date feature tell me it's a 34x auto, probably a 340 and 342.

 

Thanks for the info. I wish I was skilled enough to check the movement but my understanding is that it is removed from the front.

 

There's a good chance of it being a front loader from that era with those calibers. Is there any writing on the back saying to use a certain wrench (1200, 1260)?

 

Yes. On the back it says ' remove bezel to use admiral 1260 wrench'.

 

It's a front loader for sure. Has to be after 1958 because of that. It isn't a high beat because it doesn't have the markings or logo, so it's also pre-1967.

 

Thanks for the information. Longines seems to have made a multitude of dress watches during that era.
