A couple of years before I saw from a japanese wesite that the G-SHOCK frogman actually looks like a frog's face if you look from ``sideways''. Well, the word sideway was vaguely translated and I wasn't sure from which angle it would appear like a frog. So I picked up my watch and tried to look from different directions but I couldn't figure that out. Until today I saw the backcase picture of the atomic frog.
Appearantly the two decoration screws represent the eyes!
So here's what I think:
This is a frog opening its big mouth
Frog with bad teeth
