A nice watch, the date feature and the glow in the dark were quite helpful. It lasted be about 6 months of regular use. Unfortunately it stopped keeping time (intermittent freezing) and the second hand fell off, I'm kinda disappointed with its durability. Unsure of the initial cause, I guess I hit something with my wrist.
