The WallarGe 12.5 Inch Atomic Clock is a battery-powered digital wall and desk clock that auto-syncs time via NIST radio and shows indoor temperature, humidity, date, and an alarm.

This WallarGe atomic calendar clock combines automatic time-setting with environmental readouts so you always see accurate time, date, and indoor climate at a glance. Designed for easy wall mounting or desktop use, the unit uses three AA batteries (not included) and supports 12/24 hour formats, four selectable time zones, and an audible alarm. Its oversized digits and straightforward controls make it usable for seniors, busy households, and office spaces alike.

How does the atomic time feature keep the clock accurate?

The clock receives radio signals from the NIST atomic time broadcasts in Colorado and automatically adjusts time and date. When set to accept DST, it will switch for Daylight Saving Time without manual input. You can also override the radio sync and set the time manually if needed.

• Automatic daily synchronization with NIST radio time signal
• Automatic Daylight Saving Time adjustment when DST is enabled
• Manual time-setting option for areas with poor signal
• Four selectable time zones for regional accuracy

What environmental data does this clock show and why is it useful?

The display includes indoor temperature and relative humidity measurements updated in real time, helping you monitor comfort and protect sensitive items. Seeing temperature and humidity alongside time and date makes it easier to plan clothing, heating, or ventilation changes. Readouts are clear and useful for bathrooms, living rooms, nurseries, or offices.
