La Crosse Technology UltrAtomic Analog Wall Clock

Standard atomic clocks can struggle to receive signals in buildings with heavy interference, such as offices or concrete structures. The dual-antenna system is designed to capture the NIST broadcast more effectively, ensuring the clock maintains precise time even in challenging environments where single-antenna models might fail.

Once you insert the battery, the clock is designed to automatically search for the atomic time signal and set itself. However, if you are in an area with poor signal reception, you can manually set the time using the quartz movement override.

This model runs on a single C-cell battery. Thanks to its efficient movement and optional eco-mode, you can expect up to five years of operation before needing a replacement.

The clock features a durable, shatter-proof lens designed for high-traffic areas like classrooms or commercial offices. It is built to withstand impacts that would typically crack standard glass faces.

Yes. While the clock is optimized for atomic synchronization, it functions as a high-quality quartz clock if it cannot locate a signal. You can manually set the time and it will continue to operate with standard quartz precision.
