This is an interesting vintage Omega with what was likely a special-order dial or a Norman Morris special, as I have not seen another like it. As many of you know, the “De Ville” was introduced by Omega in approximately 1963 on upper end or dress Seamaster watches, often solid gold cased. However, a dedicated line was only brought to market by Omega in 1967. A wide assortment of dials were available (see: https://omegaforums.net/threads/omega-seamaster-a-guide-to-special-dials.151225/page-15 ), including “technical dials” from the late 1960s and early 1970s. This racing dial is very similar to others seen on Seamasters and Speedmasters of the era. I can’t give much detail on the model number or movement, as I haven’t opened the case nor had it serviced while in my possession.
