Beautiful and practical watch that is waterproof and has world time. So you can set two times that which you have currently in the destination country and that is in the home. Another highlight is that the clock has a 10-year battery. This holds, (permanently turn on the lights and stuff), depending on the behavior of the carrier in any case to the 8 years. Had me with my husband together before each one bought in the US (same model), and both batteries gave virtually the same after 8 1/2 years her ghost. A star deduction there, because this clock unfortunately always going on about 2-3 minutes in six months. I know not really from Casio. Still, I would buy it again and recommend it further also.
