Given the price of this watch I didn't know what to expect but when it arrived I was pleasantly surprised. He works very little. I have thin wrists (6.5 inches) and was only able to tighten it on the very last knot. It's actually a very nice watch. I can't comment on durability as I haven't worn it yet. Judging by the first impression, I can definitely recommend it. I forgot to mention that there is also an extra battery.
