    • My favorite…
Style meets sophistication… looks great whether outside what ring you r referring it on the town at night! Solid and rugged. Be forewarned that the face of the watch is rather large. Not for the dainty!!

    • Beautiful
I love it. It’s a beautiful watch, adds to my G-Shock collection & smartphone compatible. The app makes setup very easy. My watch did come with an empty charge, giving me the chance to test out the solar. The Texas sun did not disappoint. Best feature; getting it with Prime Day + employee discounts

    • Would Not Purchase
After only having the watch for a little over a month, the light no longer works. Very disappointing considering the cost. Would not purchase this watch again! Update, now the watch doesn’t work at all. Do not purchase!!! If I could give this zero stars I would!
