Before I became a G-Shock fan I would indiscriminately buy dept store watches. Usually Armitron or Fossil... (please don't hold that against me). Anyway, I was showing my daughter some of my old dead watches I keep in a drawer. I flipped one if them over and was shocked to see that it was a screwback! Hmmm... I don't remember paying much for it. Makes me think screwbacks might be pretty common and are no big deal??
Sorry about the fuzzy pics.. I can't figure out how to take good close-ups.
Edit: Updated with slightly better pictures.
