I got this in an auction and am wondering if it looks legit to the experts here and would like to learn more about the brand. My concerns are that it looks to me like a 1940s watch but the dial looks almost too clean to be that old. Also that the case it wrong because its not signed "Rotary" BUT I also have a Rotary ladies watch in the same style in a plated case that is also signed "Stainex" in the case back. Either way I like the watch alot but paying 90 dollars for it if it is some franken I will probably return it. Also information about the age/movement would be great.
