Casio Men’s DW5600E-1V G-Shock Classic Digital Watch Review. I bought this watch on sale years ago for normal daily wear. I thought it looked rugged, but I had no idea just how rugged it truly was until I took up SCUBA diving. It survived life banging around boats for weeks on end as I literally traveled around the world. I wore it on hundreds of SCUBA dives up to 140 feet below the surface. Whether getting me get back to the surface before my air ran out or getting me to a sidewalk cafe before a blind date ran out this watch was always there for me. My Casio G-Shock never stopped running, it never leaked and never it let me down. I can’t recommend it highly enough.
