Unlike other clocks, this travel-sized international model is small enough--less than 1/4" thick--to be carried in a toiletry kit, pocket, or purse, yet has all the features of a larger alarm clock, including a calendar and indoor thermometer, plus the accuracy of worldwide radio signal time/date synchronization. Though the date and time can be manually adjusted, the clock sets and updates itself according to radio signals sent from five global locations. Features include 12/24-hour time selection, weekday or single event alarm settings, five minute snooze, escalating alarm tone, and the choice of six languages (English, German, French, Italian, Spanish, or Dutch) for weekday display. A lock option keeps the unit's buttons from being activated while being carried or stored. 5" H x 5" W x 1/4" D. (5 oz.)
