Movement Serial No.:
Case Serial No.:
Back and movement both marked M9. Lume dots at indices and lumed hands. I'm at a bit of a loss on this one. It's too late to be a "23" and doesn't seem to be a match to anything else I can find. It seems like it should be a Date King or perhaps a President by casing and face, but the jewel count is the issue. It appears this is a first for the Db. Searching 23 jewels in the mid to late 60's came up empty. Whatsit?
