  • nice watch
Really beautiful watch, only things ,hands are very hard to see, date is near impossible to see, backlight is like a flashlight ,in case you need one ,and doesn't help to recharge luminescent hands. takes just a little exposure to sunlight to fully charge , don't sweat it, and it comes around and stays charged very well. ... show more

  • Good for G-Shock collector
I love G-Shock as a collector. It worth for money. It is not heavy on my tiny wrist. I can read the time easily, bright enough to read all. It looks great.
