What vintage Longines is on your wrist today?

Burnt

My brother-in-law brought this by tonight wanting to know more about it. I haven’t found the same reference online yet and it appears to be a front-loader, so I’m unable to open it and answer some questions myself. The case is 10K gold filled and 34mm in diameter without the crown. The crown appears to be original to the watch and everything functions as it should, though I cautioned against wearing it until it’s been serviced. I’m guessing it left the factory in the late 50s or early 60s and have no idea what movement is likely inside. Am I close on the dating and what is the most probable calibre to be found once we get it to the watchmaker? It’s not for sale and neither he nor I are interested in any valuation. I’d welcome the opinions of those more experienced, and thanks in advance for whatever knowledge you can share.

Wow, I don’t think I’ve ever seen such a late 12.68Z. What’s the year / serial number?
(Mind you I may not have been paying close enough attention to those later examples, but the design of the watch almost looks 1960s. So if I had to venture a guess I would say it’s a watch from the late 50s).

Ref. is 7111. These seem to be relatively common.

Interesting.

I had a friend whose girlfriend fell in love with mine, and he said he looked everywhere to find one just like it to give her for Christmas.. to no avail!

He must not have the same ability to search a specific reference as you do!

Perhaps he should retry his search, and give her one for Valentine’s Day! 😀

My only Longines. Have never posted this one before. The 4million 5 hundred thousand serial number tells me it is likely mid 1920s. White gold filled case made in Canada. Vitreous enamel dial. I think the hands are original. Caliber 12.92, 15-jewel movement.

My new 5356. Came from KingCrouchy (OF - a very nice and correct seller) himself:

Thank you. Sometimes a simple cleaning with water, ascorbic acid and "Rodiko" (green plasticine for cleaning watch parts) helps.
I'm not sure if the water would have been enough. Perhaps the antioxidant effect, or perhaps the crystalline structure of the undissolved ascorbic acid could have helped. I would have preferred not to try this on a more expensive watch...

Correct. The pics up above were taken after cleaning.

Nice! Makes me want to start smoking cigarettes again.

Just kidding, I never quit😟
