They sell new for that price on Amazon FYI, not sure how much luck you'll have selling it at $75.

If you’re relying on your watch to save you from a shock, you may be doing something wrong lol

That said, I wear this G-shock to work every day & love it. Solar charging & automatic time setting is great. Really can’t go wrong with any g-shock imho.

I’ve seen guys wearing all sorts of watches at work though - conductive or otherwise. Even know someone who wears a two-tone Rolex datejust on site!
