I was excited to pick this one up to make a pair of solid gold Techni-Quadrons in both white and green gold.  Unlike my green gold example with lots of interesting markings, there's not a whole lot to explain with this one.  Condition is very nice.  Edges are sharp and engravings are crisp.  There is minimal service marking, so it appears to be a low mileage example.

As usual, it's a Weber case.  I'm starting to believe that Weber may have been the sole source of cases for Alpina-Gruen branded watches aside from the occasional gold filled case imported from the US.  And once again, the serial number on this one is odd.  Weber serial numbers have a very consistent format, six digits, X0XXXX, stamped on the inside of the case.  For Gruen watches, it seems to have been 10XXXX early on and then rolled over 20XXXX, possibly at the start of the 1930s.  For Alpina-Gruen watch, the first digit is usually (although not always) a 4, for a 40XXXX format.  My other one has a 5-digit serial number engraved on the outside of the case back, which I've never seen before.  The serial number on this one is stamped on the inside as usual, but is a seven-digit number that bears no resemblance to any other Weber serial number I've ever seen.  I have no idea what to make of these two outliers.  Anyway, it's a handsome watch.  

Gruen curvex 10k gold filled precision watch Switzerland ; Mon, 19 June 2023 04:28

Any information is helpful. I believe it was made in Switzerland in the 1940's. States that it's 10k goldfield, very nice timepiece. I've personally never seen such a beautiful timepiece.. I do not believe the dark blue band on it is original and also the band is not in the best of shape. However I could be wrong as I am not an expert. I have no clue as to the value of this timepiece and really don't know much about Gruen Curvex 🤷‍♀️

If anyone has any helpful information, I would greatly appreciate it.

Nothing too exciting, but I don't recall ever seeing an Alpina-Gruen with a solid gold Cincinnati case.  I knew that Gruen exported some gold filled cases to Alpina, but I thought the precious metal cases were all Swiss, mostly Weber.  It's kind of weird to see a German assay stamp on a Cincinnati case.  Anyway, posted here for posterity.
