I recently came across my grandfather's Omega which was given to him by AT&T in 1978. I'm having trouble figuring out what it is though since all the face says is "Omega" and "Quartz". It has a gold face like the Constilation and it also has a date movement. Any help would be apperciated, I've tried to attach a picture.
This is my first post so if this is the wrong location I apperciate your patience....

if you can get the caseback off and give us the reference numbers on the inside of it that would be a great help as they identify everything about the watch. also the serial number on the movement would be a great help for dating it. on a quartz movement it will probably be inside a circle which also has the omega logo on. it will be very small so magnifier needed.
with that information there are a huge number of people here who will be able to help. just from looking at it i would say that its probably 1980's and gold or gold plated case.
hope that helps
