Another lost watch found

I imagine you must get lots of these on this forum, rescued from my deceased 86 year old uncles house in Surrey. He was an antique collector, and enjoyed the fine things in life, however I have no idea if this watch is a cracking rarity, or an every day omega. Perhaps some experts on here could kindly advise me, if it is valuable it would be nice to have an idea as I need to do the best by the beneficiaries of the estate, however if it’s a piece of old tat I don’t need to worry too much. I think the photos tell the story, the watch is probably best described as very used, however I have bench tested her over the last week and she keeps good time .May I thank in advance anyone who can offer me any assistance. Kind regards, Steve

This is what Omega shares from its vintage database. As you can see, many different dials were used.
