Maybe Marcus had a few original cases(never seen Cal1002 only Cal1012) It would be interesting to see them.
The starburst finished watches seamed to originate from Yvonne at Watchmeisteren. A den of iniquity if ever there was one. I have always suspected these were fake, and I was looking at the cases in detail again while discussing the watch with Stuart Solomans. I compared the case engravings and the disparity between the original Omega case and the 'service example' are damning.
For one I have never seen the triangle with sharp points on any other Omega case, and for another the EPSA logo is inconsistent with others. The diving bell looks more like the little man from Bod, or a head with a dress. If you are making a case you are unlikely to get your own logo wrong, whatever else you mess up!
I went to Watchmeister in about 2010 to return one of these watches because I doubted its originality. At that time the low quality of the finish and casting disturbed me. The milling is carried out in a different direction to make the lugs and the double spring bar holes are missing. They told me they could get these cases directly from Omega, in later years this story seemed to modify to them being rescued from a bin of parts destined for destruction. I think it is more likely they came direct from China. The amount of them now out in the world is quite disturbing! It has made one of Omegas rarest birds almost ubiquitous. I think the value of them has been influenced massively.
