When work, school, and life's other commitments pull you away from the cockpit, Trintec's 3.5" Altimeter Desk Model Alarm Clock is just what you need to help you get through the day. In place of a standard analog face, this 3.5" x 3.5" clock features an aviation-themed display styled after a conventional aircraft altimeter - complete with Kollsman window! Besides its pilot-friendly appearance, the unit features a top-of-the-line, American-made Quartz movement paired with a high-impact styrene body that'll hold up to the occasional hard landing. Runs on a single AA alkaline battery and includes a 1-year warranty. A high-quality, value-priced timepiece that's perfect for aviation enthusiasts of all ages.
