So I bought this watch for my clinical watch during nursing school, and let me tell you, this thing is amazing. I have had it for about two years now and have never had to change the battery (and I don't pull the pin out to stop the seconds hand ever). I wanted a watch that had a seconds hand (for nursing school), but also had a stopwatch that I could control. The LED light up is bright enough to see it clearly in the dark and the hands glow in the dark! I have for sure tried out the waterproof by jumping in lakes and multiple handwashing. This thing has gone above and beyond my expectations. It has lasted longer than all my other watches and is like half the price! I recommend this to anyone who needs a watch that matches their fast paced lifestyle. I can control the analog to go from 12H time to 24H time as well as the date and alarms!!! Amazing But it! You wont regret it.
