Omega De Ville Prestige 4300.31 History & Cal. 1120 Info

Hello everyone,


I recently inherited an Omega De Ville Prestige 4300.31 that belonged to my late father.


Unfortunately, he passed away when I was young and never had the chance to tell me anything about the watch. After his passing, it remained stored safely for about eight years. When I turned 20, my mother gave it to me so that I could start wearing it and continue its story.


The watch means a great deal to me, not because of its monetary value, but because it is one of the few personal items I have from my father. My goal is to preserve it for the rest of my life and hopefully one day pass it on to my own son so that he can wear it with pride and remember his grandfather.


A watchmaker recently inspected the watch while removing a bracelet link and confirmed that it is authentic. He also told me that it was a watch worth taking great care of, but he could not tell me much about the model itself.


I would love to learn as much as possible about this watch and would be very grateful for any information from Omega enthusiasts and collectors.


Some questions I have:


  • What can you tell me about the history of the De Ville Prestige 4300.31?
  • How is this model viewed by Omega collectors today?
  • Is the Calibre 1120 considered a good movement and what should I know about it?
  • Are there any common issues I should watch for as the watch gets older?
  • How often should it be serviced?
  • Are there any specific maintenance tips for preserving it long-term?
  • Does the model have any interesting history or features that are not widely known?
  • What would be a realistic market value today for a watch-only example without box or papers? I am not planning to sell it, but I am curious.

I have attached photos of the watch and movement.


Thank you all in advance. Any information, stories, or advice would mean a lot to me.

You've inherited a very nice watch and while not as well known as the Seamasters and Speedmasters, it's a most elegant dress watch.

I think most of your questions can be aswered by the information posted above. If there's anything else not covered there, let's know.

Regarding the service interval, the AI suggested 5 to 7 years is good guideline if you are wearing the watch a lot. But if you wear it only randomly, like once per month or for special occasions moder service holds its shape something like 20 years.

I think 20 years would be pushing the limit of effective life of the lubricants.
Even for a seldom worn watch I'd not go beyond 10 years.

I’ve removed the ai reply as it causes genuine harm to the site having that indexed for search, I would very much prefer people didn’t post any of that here, I realise the OP did use AI to format their thoughts which isn’t ideal also but they’re trying to include information we ask them to when asking about a watch

Yeah, could be, I haven't yet kept that long record for any of my watches that I certainly know the service history for. 2 decades is just something couple of watchmakers have meantioned to me.

I'm now keeping a record for my watch servicing schedule with timegrapher photos showing the amplitude. So in 15 years or so I'm wiser regarding this 😄.
