I saw this watch listed as a vintage 1940s piece, but I'm unfamiliar with the name on the dial 'Supreme' (it's also the name on the movement). And I'm also wondering if anyone knows what the red mark on the dial is.
Seller said something about it being a nurse's watch but I'm pretty sure that has to do with what they used to call duo dial watches and that it doesn't have to do with the red marking. I'm not sure if he was implying it's a Red Cross insignia, bc I'm pretty sure that's not what the cross looked like even back then or why it would be on a watch's dial for that matter.
Anyway, here are the links to the pictures posted on the site:
Thanks in advance for any help!
