Firstly let me introduce myself. I have recently started collecting Constellations and have decided to concentrate on solid gold. If for no better reason than I would be tempted to buy dozens otherwise! My problem is that the more I read the less I know. I've just got the idea that "something" is a general rule and then there is an "except"! Take the first image, an allegedly early '70 watch. Calibre number seems OK but no movement number? Second image of the back case inside shows OWC Does this means its an English case as shown by the hallmarks? The "perlanging" ?? seems a bit rough. The third image shows another. Calibre 751 with movement 2?90878XX. Date about 1970 again? But the inside case shows very little. Is this how they were from the '70s on? Thanks. Vince
So...looks like you have some reading to do before you get the gold. As far as the Constellation goes, you won't find better or more information anywhere!
