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.
