Hello OF! I've decided to check a box off of my list and find a 2531.80 Omega Seamaster. This watch is the pre co-axial model with the Omega 1120 movement (1990's - early 2000's model). I am extremely anal about my watches, and prefer a mint example with the full kit (box/cards etc). Feel free to send me a PM if you're looking to sell! Thanks, Garrett
