Dating research using a quick look through advertisements.

From 1935 gruen switched from guild to “the precision watch”. In 1938 same lettering for Gruen started. In 1939/1940 the crest disappeared in the ads. In 1939/1940 Precision lettering was more graceful Looking (like on the box). In 1941 you see trademark behind precision. Trademark disappeared in 1948. In 1950 the precision writing looks different again.

I have seen this box with a veri-thin Baylor, All star 1 and my ladies veri-thin. She has a movement cal 215 (>1948) and the case style is from 1950.
