Welcome, cyberbeer! Thanks for sharing this interesting model with us. Looking forward myself to finding out more about it! I edited the message to add the pics in line.

If possible, it would be most helpful to see the movement & inner case back.

Congrats with having a watch with some family history!

The dial looks like an early redial. 21 rubis is not something I have seen before. And instead of antimagnetic I would expect veri-thin or precision.
Guildite case?

I hope others can tell more.

Agreed, that dial has been refinished. And without the original dial, it might be tricky to ID. Maybe one of the data jockeys here can narrow down a date with the case serial number.

I unfortunately can't nail down the date by the serial. The case serials have always been maker related and we would need to know the case maker to compare. I don't have any nearby datapoints which would be fitting. The datapoints around would be 14k cases by K&O form the late 30s, but this will be unrelated.

Somehow my answer yesterday did not make it through, I also agreed that the dial had been refinished. I never saw antimagnetic written on a Gruen dial of this periode and I also do not really believe in a 21 jewel movement. Also Gruen did not use the term rubis on their dials.

Hi,

thanks for your feedback and information!

Do you think that the dial was substituted?
I didn't find any information about the Antimagnetic...

Do you think that the substituted dial is an original Gruen part?

Thank!!

The dial isn’t substituted, but repainted. If a dial got damage (from water or radium burn) it was normal to do a redial. They removed the paint from the (brass?) dial and used stamps to get it spickandspan again. Sometimes the redialer didnt have the correct templates… and/or he worked from memory.
.
Maybe a watchmaker or jeweler can open the back for you. A picture from the movement and inside case back would be helpful for identifying it.

There are Anti-magnetic Gruen watches, but that was marked on the caseback. See for example : https://www.ebay.ph/itm/VINTAGE-GRUEN-CHOCK-RESISTANAND-WATE R-ANTI-MAGNETIC-AUTOMATIC-17J-MADE-IN-SWISS/143857200339

I agree with Jenneke, usually the original dial was just repainted. Due to the fact that it says RUBIS instead of JEWELS I expect that the work has not been done done in the US but probably a french speaking country. Or Italy in your specific case...
