Black quartz SMP from post 2008 ie the time of the first 2500 Co ax auto models, but that’s the quartz version.
It is not 2531, but still a nice watch imo. As padders said, it is 41mm quartz version, reference no. 212.30.41.61.01.001 https://www.omegawatches.com/watch-omega-seamaster-300-m-quartz-21230416101001
Not particularly rare and not particularly cheap. 10 year old quartz model. rarer in black than blue but still not all that unusual. On here it would change hands at around circa $1300-1400 maybe. An SMP quartz makes for a good daily beater, I use a 2265 myself regularly, but have little collector value if that is what you mean.
Indeed, if you want a quartz which has some collecting-factor, you should have a look for 2541.80 or 2264.50. 2221.80 and 2265.80 are probably less desirable, but still are the great proposition if bought for a reasonable price.
