I bought this watch in August of 2014 and it is now June 2018. I use this thing daily in a steel shop environment so it's been through just about anything you could think of from being knocked around to exposure to heat and cold to exposure to chemicals and welding arc. It's still going on the original batteries, the buttons still function, the lettering is all worn off but the display is still readable and the backlight still works. The only thing wrong with it right now is I tore the strap across the holes by getting it snagged on something but that's no defect of the watch just my use or misuse however you want to see it.
