I bought this watch after using a similar GShock for fieldwork. It does everything you might expect it to do: secondary timezones, fully functional stopwatch and timer, with the timer capable of auto-repeat. The auto-repeat timer, 10 year battery life and GShock reputation of durability were why I bought it, and I haven't been disappointed.
I never had any doubt about the quality of G-Shock watches. And this one is a fabulous watch for 24*7 use for 10 years. You don't have to actually think about anything, be it dust or water or anything like that. Play, swim, jog, run, and have fun anyway you want with this watch over your wrist. The best part is flipkart service, I got the watch the very next I had ordered it. I am really very happy with the quality service from Flipkart.
