This is a cool ad I found... I don't think we have it.. but it shows the Knight model. I believe this is going to be around 1938 as the Montgomery is there... as is the 37-38 Ranger model as well as the 1939-40 Banker
This ad is weird... it's got models from like 1937-1939.... it was from a Jewelry store so I'm wondering if they're displaying the models they still had in stock... so while this ad was probably 1939-1940.... It still shows earlier verisons of the Ranger... and President.
Here's the ended listing for this ad.... I don't see a date on there anywhere. Looks like it didn't sell last night so the guy may put it back up. He/she thought it was 1950's... obvious mistake.

Agreed--not even close. Your watch is 15 - 20 years later in time and an entirely different size, shape, and style. Take a look at the late 1930s - early 1940s Minute Man in the database, and you'll surely see the difference. If that doesn't convince you, then we can compare case and crystal measurements.
