Here is an interesting one. Case and movement M6. Four quadrant shadow dial with date window at 3 position.
I find no instance of this face with stepped solid markers at 12 and 9 anyplace in the database.
Movement says Date King Variant and the only other similar faces in square cases found in the ads with similar stepped indices were all Date King variants that aren't represented by submitted watches . Among these were the GG and NZ; both of which appear to have shadow dials based on short ads. None are a match to subject watch. My first thought was it was a marriage, but I now don't think so.
Variations of this case design were used for Engineer and also Diamond Excellency; so the possibility that this is an undocumented something else is not out of the question. This appears to be the same case as Engineer. Inside of back is stamped 2621. High domed crystal is a perfect fit.
There is one watch listed as an Engineer that is a 1967 with a date window, sunken subdial and different indices that I believe may have just been ID'ed as such for lack of a better place to put it.
