Sleek, stylish silver color expansion band watch with great features for the blind and low vision at an affordable price! In the USA, the Reizen talking radio-controlled Big Face Atomic analog Watch receives a daily signal from the NIST Atomic Clock in Colorado, the nation’s timekeeper, ensuring accurate time and even accounting for Daylight Savings changes – so you never have to set it! Time is announced in a clear male voice at the simple touch of a button. A second touch of the button gives you the day of the week and the date (month and year). Other features include an hourly chime (which may be turned off), alarm, and a large 1.50″ diameter traditional white analog face with bold black numbers and big hour, minute and second hand. Jumbo size silver-tone case with comfortable silver color expansion band measuring .87 inches wide. Face with bezel is 1.69 inch diameter x .59 inch thickness. Weighs .2 oz. Battery included (CR2032). Note: The radio-controlled function will work only in the USA (except Alaska and Hawaii), UK, Germany and Japan. When outside these areas, the watch can be set manually to reflect the correct time on the analog face, but the announced time will not be accurately updated. Compared to other time-signal transmissions in higher bands (WWV, GPS, etc.) long-wave signals have a number of advantages. They can go around obstacles such as mountains or buildings. Since no line-of-sight is necessary between the transmitter and receiver, a single very powerful station can cover a huge geographic area. Long-wave signals even penetrate the walls of most buildings quite well. Propagation happens mostly in the form of a ground wave, such that transmission delay is less affected by the variability of the ionosphere. Battery Type: CR2032 NOTE: Atomic Radio-Controlled NIST Time-Setting Function is ONLY available in: 1) USA (excluding Alaska and Hawaii); 2) United Kingdom; 3) Germany; and 4) Japan. However, the time is easily set manually wherever there is no accessible atomic signal.
