Hi all, I have this Marvin Hermetic watch and I’m wondering if anyone has information on how it opens.

I do not see any obvious areas to pry off the back. My assumption is that it is a screw off back and is just VERY stuck or cross threaded. I’m thinking that I’ll need to use the socket trick but I’ve never done it before.

I’m very new to watch repair so any and all help and advice is greatly appreciated!
