I bought this watch at the end of November 2017. I used them several times a week while swimming or exercising. Made in 3 months! Broken, buttons no longer work. These are cheap watches and they are cheaply made. I won't be experimenting with watches anymore and I hope by reading this I'll save you some loose change. If you really want to buy a cheap watch, buy a cheap CASIO watch that will last you many years, it's $10 and cheaper than this junk! and if you want a big screen, Casio has one too for just $16.
