Review: Yes - Very nice
Review: I believe that this model is discontinued in North America. You may be able to find a style that you like at a retailer and if you want it, I suggest you buy it. desertcart delivery was exactly as expected. Watch is very beautiful with a blacked out dial with red accents. If you like a digital display, this watch is not for you. The digital display is very small. Very light and comfortable to wear with not having a bulky G Shock. You won’t break the bank to purchase this watch, so it is a great everyday beater or vacation watch.
