Help recognize vintage Omega sector dial, plz?

[Franz2288]

Hi, I was wanted to ask if anyone could help me identify the model and/or reference of this vintage Omega. Case, dial and hands should all be original but I am not 100% sure of that (inherited from aunt). There are no inscriptions on the caseback.
Thank you in advance for the help
