http://www.hnco.com.au/articles/hnco-guide-to-omega-watch-serial-numbers/ FYI Just posting this here for reference purposes. I was also trying to figure out what date range this guide works for, as it doesn’t relate to many Omega watches I’ve seen here. Or I might have had too much to drink They do have some nice pieces though, this Constellation dial is pristine
That dial has been refinished. Faceted edges are no longer sharp, second track is too far away from the applied figures, much of the printing is too heavy and when looking at the back there are traces of superglue used to reattach the applied figures. So much for "new old stock".
That post is not exactly right for the reference numbers which they refer to as serial numbers. And is only valid for certain ranges of years. 40’s? To @61 ish If I read it right only the 4 digit numbers work but it attemps in error to make it work for the 145.022 era of reference numbers.
