I have been using the g shock gw-9400 the last couple years. It has been a great watch, with some very useful features.
My dad has an original triple sensor casio. It's close to 20 years old now. Still runs like it's new out of the box.
Still haven't shot that one yet. There are some decent cheap uppers that I have ran. Hardened arms being one of them, they even have quality customer service.
I have been thinking about introducing my mom to one. She currently has the shield and has a hard time manipulating the slide. I think that's the only real upside to this particular gun.
