The MARATHON Large Travel Alarm Clock is compact and ideal for travel. Its locking flip cover keeps it folded, making it easy to slip into pockets or carry-on luggage. This clock can also be used as a desktop clock thanks to its large, legible display and desktop stand, making it a true all-purpose clock. While keeping size compact, Marathon has not compromised any functionality of the Travel Alarm Clock, displaying time in 12 or 24 hour formats. This clock uses a large, ergonomic and easy to press button to activate the included backlight. The MARATHON Travel Clock includes 2 AAA battery and is low power consumption to ensure maximum lifespan.
