I don't know if those papers are correct for the watch, the serial range is good for this watch type 13.9 million being in the 1950's which is when I expect this watch was made. Yoy need to have it opened to check the number on the movement.
The ref of 589 make no sense to me either. If you search for Omega 14350, 14363 and 14383 you'll find watches of the same design.
Have you been given it or bought it? If so, the price you paid will be a good indication of value unless you think you got a deal.
Roughly speaking, if the dial is poor/average maybe £500-600. If it’s very good with no marks or damage probably £1000
Why ask what it’s worth if you know the value?
Are you sure you've seen them sold for $2.5K? An asking price from a dealer is different to a selling price between collectors. The bracelet doesn't add anything here, firstly it certainly isn't period correct and secondly I have my doubts about whether it is a complete Omega bracelet or just an Omega clasp on a random bracelet ( my feelings are the later )
If I were to see this watch at a watch fair and be able to inspect it in hand then if the dial were good ( which is hard to call 100% from the poor pictures and under the scratched crystal ) and the case wasn't polished and the bezel wasn't scuffed up ( first picture it looks possible ) then I'd be looking to buy it for around €700-€800 max as I like this ref. Others may pay more or less.
