Jack,
you might be perfectly right. Didn't they register the Guildite trademark in 1933?
Alpina Gruen was started in 1929 and the colaboration started to cool down in 1933. So most Alpina-Gruens are dated between 1929 and 1933.
But do not gorget that for the Alpina-Gruen watches different rules apply. These were intended to be sold in Europe and here European trademarks rules applied. The casemaker not necessarily stamped Guildite in the back even also when watches for the US from the same time had the mark already.
I also have one Alpina-Gruen with the Staybrite marking which makes it more likely being pre 1933 but I would not take it as a proof.
