Excellent Used condition Omega Chrono Seamaster 300M silver dial.  Dial is 30.5MM and is silver with silver sub-dials.  This Dial was the original dial on my Special Edition Seamaster. (Omega Seamaster Special Edition Chronograph 2589.30) Very small mark at the top of the right hand sub-dial.  I did not ever notice till I magnified the dial - probably will never notice but I wanted to make the buyer aware.
