The watch has an hourly chime/time announcement which can be turned off. Audible cues help the user navigate through alarm settings and other functions. Each Talking Atomic Watch with Leather Band requires one CR2032 battery, which is included, and comes in a stylish blue gift box.
About the Radio Signal (Atomic Function): The radio signal that controls the time, day of the week and date is broadcast through a radio station in Fort Collins, Colorado. The station is operated by the National Institute of Standards and Technology (NIST), which is the U.S. Government agency that provides the nation's official time. Your watch is programmed to listen for the signal coming from this station overnight when it is strongest (at 3am, 4am, 5am and 6am daily) until the signal is received and your watch time is adjusted accordingly. You may also cue the watch to attempt to receive the signal on demand.
Important Note: The atomic function and calendar will not operate in Alaska or Hawaii because the watch cannot communicate with the National Institute of Standards and Technology from these states. However, it may still be used in those two states as a regular 'manual-set' watch.
