I think a lot of the issues that come from this watch are due to the fact of how popular it was in the 90's and early 2000's - it was technically the watch that "saved Omega" in many ways due to it's James Bond association.
Because of that, a gigantic amount of these were sold to people that didn't care about keeping paperwork or boxes of any kind, who often bought mid-sized models or even quartz ones not knowing the difference between them and the full size automatic and at one point about 10 years ago, this was probably by far the most common pre-owned Omega I saw in nearly every jewelers/pawnbrokers window display - usually always in poor condition or missing half the bracelet links or with no box/papers.
I personally purchased one in 2014 that was made in 2005 and it had over half the links missing, no box or papers, was mirror polished by the previous owner and had a miniscule chip in the sapphire. It was my first Omega and cost me £1,050 - I bought it because I couldn't afford a £2,300 Speedmaster or a £3,400 Rolex Submariner. I sold it about 3 years later for £900.
The 2531.80.00 is a nice watch but actual good examples of them seem very few and far between - especially 90's ones. One thing I will add however is that the handset on it looks a bit weird, they seem too small in length and a bit out of proportion for the dial. I think the 2500 co-axial model fixed this.
