Need help identifying

Here you go, everything you need to know.
Model "Monte Carlo", yours just has another dial variation.

These movements can be fussy about the battery they use. The battery specified for the 1432 is Battery 9.50 x 1.60 mm type 373.
Although Omega usually specifies Renata batteries, I've found other quality brands are acceptable such as Seizaken, Seiko, MuRata, Maxell.

Also, as the movement has been static for 20 years, it could require a session on a train release machine. This operates the machinery in the movement and frees up any of the gears that may be stuck by dried oil or grease.
It would also benefit from a full quartz movement service if the circuit block is still functional.

Although all of this may get the watch working, the cost involved will quickly outweigh the value of the watch.
