This is identical to another watch I have. I thought it was a Watertite “P”. However, the 1950 Watertite “P” that’s in the database has a snap on case back and this has a screw on case back like the Watertite Duo Wind “E”. While the other Watertite Duo Wind “E” watches have Duo Wind on the dial and this says Selfwinding, we have seen other Duo Winds that are like that as well. Being both top cases are visually identical, the key difference is screw on case back vs the snap on case back.
Here’s my other watch.
Here are the watches I made reference to.
