Dial: Excellent condition matte black A5 dial with radium lume that has aged to a deep orange hue with some spotting.  The hour and minute hands were relumed and color matched to the hour markers.  Both the hour markers and hands glow brightly when exposed to UV light then fade quickly.  The radium lume has been verified by a Geiger counter.
 
Case: Very good condition 39mm stainless case that appears to have been polished in the past and shows wear from use.  It remains thick with clearly visible bevels.  The hippocampus and Omega symbols are also clearly visible on the case back as are the bevels.  The DON bezel insert is in excllent conditon showing light wear and has faded to an attractive grey hue.  The crown and pushers are correct for this reference.  The ref 7912 bracelet date 1.62 is in very good condition with some stretched links. The no. 6 end pieces for the bracelet are reproductions.  
 
Movement: The Omega cal 321 movement serial number 19,583,xxx (correct range for a 2998-61) was just serviced by Giovanni Passalacqua of the Independent Watch Service of San Francisco and comes with the remainder of a 2 year service warranty. It's running very well with all functions operating correctly.  Of special note is the fact that the movement was adjusted to two positions from the factory and is engraved as such.
