Old watch

[USMC18]

Found this watch in an old park. I am kind of curious of how old it is. It has what looks like a rotating bezel on top that doesnt move and has number around the edge of the watch. Not very heavy, really not sure what type of metal it is. Also there doesn't appear to be any writing on it besides the numbers. If anybody has any info on the watch, it would be greatly appreciated!

I don't know a great deal about watches, but I recognize that it was a divers watch style, which a lot of cheap ones were made (particularly in the 90's, in my mind anyway). I think you would want the base metal to be bronze/brass which holds up in salt water, but I could be wrong about that. Anyway, it doesn't look like it is either of those, so my guess is that it was a cheap one.
