that regarding the Suwa logo on the 6309-704x casebacks, on my Japan-A models the "two inverse 1's facing each other" appear in fact to be the Suwa logo (although very small and hard to make out). Comparing the mark on the caseback to the Suwa logo on the dial makes me think they are one and the same mark. Anyone else see what I'm seeing, or do I need another beer? (I'm having another anyway, so it's a "win-win" for me!)
Fantastic read! Makes me love these old workhorse divers even more. Thank you very much!! It must have taken a great deal of time to put that together.
