Vintage Omega Identification help

Please can someone help me identify this watch. Found it im my father's drawer. Would like to restore it. It is working, it must be serviced, crystal replaced, dials either polished or rhodium replated, i dont know.... i assume that it is dated 1940-1950

thank you in advance

thanks for answer,

unfortunately, i don't have watch to show case back, and when i took pictures i posted i didn't took case back photo 🙁 , i left it at Authorized Service center last week, and i am waiting that they ring me back, in meantime i am trying to investigate myself.... If i remember correctly inside case back was engraving, steel something, outside was empty.... I wound watch and amplitude is expectably low, around 200, beat error is below 1, and rate was below -1 minute per day. Honestly i was surprised that is running

Thanks for advice, this one where i left it will examine watch and will call me to tell me what is art of possible. There will be no further actions if i dont agree. When i dropped watch off, old watchmaker looked at watch briefly and told me about rusted hands that they were rhodium plated, and that he dont know if they can be replated or only light polished (must see rust level) he looked through this scratched crystal…. Let’s see i hope for best, i would really like this little piece to be restored as best as it could without loosing its charm
