Grandfather's Omega

[BlueAZ]

Hello,

My mother just gave me my grandfather's old Omega watch. It is not running (it probably hasn't seen the light of day in 30 years). There aren't many identifying marks on the exterior other than "Swiss Made" at the bottom of the dial and "Quartz 1432" on the case back. The case and face are gold in color and the date has a white/gray background. The case back is silver in color.

Any idea what model this is?

Thank you!
