help with vintage omega seamaster

I would like to see if anyone could help identify this watch for me and also tell me if it is real or a fake. This is a watch that has been passed down and i don't know much about watches. I have looked on google a bit and haven't seen one that looks the same as this. I am guessing its from the 50's but that is just a guess after talking to a couple people. i haven't had the back off yet, hopefully tomorrow i can make it to the omega dealer in town.

thanks in advance
