I ordered this watch January 14 and received in excellent condition in Quebec City (Canada) on January 23 as planned. It was completely packed, with air cushions inside and embedded in a metal box. Once unpacked, I was amazed by the look of this watch! But I still had not seen anything. With instruction manual in hand, I quickly found that it was Radio-Driven with a rechargeable battery to sunlight or other light source. So never stack to replace. Also, the time accuracy is to the second year, as synchronized with the atomic clock in Fort Collins, Colorado USA World Time is visible in forty-eight (48) different cities. It has a Stopwatch Countdown and the twenty-four hours in 1/100 second. It is also provided with four alarms whose BEEP unfortunately, is too weak and too short. I anticipate the day or change this obsolete Casio Beep VIBRATION and a period of twenty seconds. I have one with this option and it is SUPER !!! The dial illumination is enough, no more! If programmed auto lighting, it illuminates the dial to the simple sunrise arm but not the day, because it is saving mode of the stack and it was not until the coming darkness, the LED occurs. CAUTION: If programmed ENERGY SAVING, the automatic reception function at night will not activate. (See pages F-70 & F-71) Note the following function, which is unique to CASIO: If activated, at the touch of a button, it displays the time and date of the signal detected at night. (6 Alerts) Of course, if programmed, it automatically switches either to summer time or winter. The bracelet is very good, with its security clasp. PS I weighed this watch! It showed six ounces or 172 grams! So surely not too heavy !! After checking all options of this wonder, I can only recommend unrestricted to potential buyers. After visiting all sites in 2014 and it is unquestionably unique and SUPER WATCH Casio has produced. I know a little in this area, since I have 30, three upscale Citizen. I thank AMAZON giving me the opportunity to purchase this superb watch online. By far and after visiting several sites, will now AMAZON mine for future purchases. THANK YOU!
