Omega Seamaster 300 Date Case: 166024-67 SC Movement: 282727xx Caliber 563 Picked this up from the estate of the original owner who was a Naval Aviator in Vietnam, at a gun show of all places, about 10 years ago. Had it serviced at WatchCo around 2010 (I was living in Shanghai then). They replaced the crystal with the one with the Cyclops, it does have the Omega etched in the middle. This has the more unusual Cal 563 and the Naiad crown. The lume glows for a few seconds when charged under intense light. Thought about trading/selling it a few times, but came to my senses each time [/URL ] [/URL ] [/URL ] [/URL ] [/URL ] [/URL ] [/URL ] [/URL ]
