The 13mm x 15mm 17 jewel movement (not working) is a 1952 Longines (8887924), though I'm not sure it is original, as the dial face is square. I've requested history on it from Longines.
The case appears to be solid 14K yellow gold. Inside it is inscribed "CASED AND TIMED IN USA by LECOULTRE" and "14K.GOLD" and the number 497628. The outside has "14K GOLD APEX".
What style is this? I have not seen similar in my searching, though it is likely because I don't know what to call it! Is it of 50's vintage? I found a JLC wiki but those case codes do not concur with this case.
Any opinions on the originality of this combination considering the misfit dial? Though the case inscription suggests it was never a JLC "brand" watch?
Obviously it needs work. I suspect the case is more valuable than the mechanism. I was quoted $160 USD to restore it. I'm taken by the design, it could make a nice gift. But maybe not valuable enough to justify the expense?
Many thanks in advance for your insights!
