When asking for help like this it’s best to provide as much information as you possibly can along with lots of good photos. That one photo doesn’t give us much to go on.
Yes, what everyone said about getting the watch opened -- you'll learn a lot about it.
To me it looks early 60s; the case components could be gold plated or solid gold (the inside of the caseback should indicate which). The crystal is acrylic, so get yourself a tube of PolyWatch on Amazon and buff those scratches out; it works like magic. All in all, an attractive vintage watch which you should be proud to wear.
edited p.s.
The crystal appears to be OEM (original equipment manufacturer) because there is a tiny omega symbol etched on the underside of the crystal at dead-centre; this means it could be the original crystal that came with the watch when it was first purchased, or a service replacement. In any case, having an OEM crystal makes the watch more interesting from a collecting and aesthetics point of view.
The case, crystal, crown and dial are all original and if the movement is in the same condition as they are, that was a very nice gift. BTW are you located somewhere near the Arctic Circle, or maybe on a floodlit football pitch?
