WallarGe Atomic Digital Wall Clock 12.5" — Self-Setting WWVB, Indoor/Outdoor Temps, 2.5" Digits

This compact, easy-to-read digital clock pairs an internal atomic receiver with a wireless outdoor sensor so your display stays synchronized to the official WWVB time signal and shows both indoor and outdoor temps. Its large 2.5-inch tall digits, selectable time zones, and simple battery-powered setup make it a convenient timepiece for homes, offices, and senior-friendly spaces.

How does the WallarGe atomic receiver maintain accurate time?

The clock contains a WWVB radio receiver that automatically syncs daily with the U.S. NIST time signal, keeping time accurate to within one second. It supports automatic daylight saving updates and can be switched between four continental U.S. time zones for correct local time.

• Daily automatic synchronization with NIST WWVB broadcast
• Accuracy within one second after successful updates
• Auto daylight saving time adjustment
• Selectable PST, MST, CST, EST time zones

What temperature information does it provide and how?

The clock displays both indoor temperature using its built-in sensor and outdoor temperature via a battery-powered wireless sensor. The outdoor sensor transmits readings up to about 100 feet away, allowing you to monitor exterior conditions from inside.

• Indoor temperature measured by the clock’s internal sensor
• Wireless outdoor sensor transmits up to ~100 ft (line of sight)
• Temperature units switchable between Celsius and Fahrenheit
• Clear numeric display shows temperature alongside time

Is the display easy to read and where can it be placed?

The WallarGe clock uses a bold 2.5-inch high digital time display that’s readable across a room and can be used either mounted on a wall or freestanding on a desk. Its minimalist layout and large numerals make it particularly suitable for kitchens, living rooms, bedrooms, offices, and spaces used by older adults.

What power and alarm features should I expect?

Both the main clock and the outdoor sensor are battery-operated so no cords are required; batteries are not included. The unit also includes basic alarm and day/date display features to help keep schedules and reminders on track.
