guys, that is a great thread. some forensic investigation...... that is what it`s all about among collectors ! be very polite in achiving a result for the greater good. my hat is off to both of you. during the auction i did not want to interfere with more comments. but the first gut feeling, i had, about that case was a Movado case. on the other hand, movade signed all cases as well. so, the only guess would be a one-off from the case maker for omega/movado/.......later recased to fit a different mvmt. & dial. the service marks belong to the case; whatever it started it`s life with. if the omega inerts have been added later, the case marks have nothing to do with the current setup. for the present state, i think the auction result is a good one. kind regards from down under. achim..........and, BTW: Alain is a very passionate omeganisti, yes ! an excellent continuator for the work, John Diethelm started ! Omega can be proud of these guys; many other big Swiss Watch Manufacturers could learn a lot from these guys, who preserve the history and write new history.
