20 Questions rules apply. Begin. (Mind you, I've given you the branded box, so this is going to have to be pretty specific)
Well, I can safely move past "animal, vegetable, or mineral" using the picture, and the fact this is a watch forum, as my first clues. ...... unless you have a pet amphibian you haven't told us about yet. That box looks like it's from the 40's or 50's judging by the font. I'll ask question number 2: 30CH or 13Z?
It is a 30CH. I made this too easy. Anyone wanna go for the ref.? Dennis, it's gotta be a yes or no question. That's the way I learned it.
