La Crosse Technology 14 in. UltrAtomic Stainless Steel Analog Wall Clock with Shatterproof Lens

The UltrAtomic wall clock features the most accurate Atomic movement on the market. Like a traditional Atomic clock, this clock automatically sets itself and updates for Daylight saving time. However, this clock is equipped with two antennas that allows it to work in the nosiest, hostile electronic environments such as busy office buildings, hospitals, or other institutions. DUAL ANTENNAS=ENHANCED RECEPTION -UltrAtomic clocks feature two antennas, whereas traditional atomic clocks only feature one. The extra antenna increases the WWVB signal reliability and penetration. EXTRA BATTERY COMPARTMENT -To keep your Ultratomic clock running longer, the movement features 2 additional battery compartments that allows you to add extra batteries (optional.) This keeps the clock running for approximately 4 to 7 years before you need to replace the batteries. ECO-MODE -Eco-mode is a battery saving feature that stops the second hand at 12:00 between the hours of 11:00pm-5:00am.
