WallarGe Atomic Digital Wall Clock — Self-Setting, Auto DST, Large LCD (Black)

WallarGe Self-Setting Atomic Digital Wall Clock is a battery-powered timepiece that synchronizes automatically to WWVB signals and adjusts for Daylight Saving Time when enabled.

This atomic wall clock combines a large, easy-to-read LCD with features you expect for home or office use: automatic midnight synchronization to the national time broadcast, selectable U.S. time zones, indoor temperature readout, alarm functionality and a simple 12/24-hour toggle. Because it runs on three AAA batteries and requires no power cord, it can be mounted on a wall or placed on a desk wherever a clear digital time display is needed. The design prioritizes legibility and low-maintenance operation so you spend less time setting clocks and more time relying on accurate timekeeping.

How does the clock keep accurate time without manual setting?

The WallarGe clock includes a built-in receiver that picks up the WWVB atomic time radio signal each night and updates the display automatically at midnight. You can choose among EST, PST, MST or CST so the clock reflects your local zone without manual calibration.

• Automatic nightly sync with WWVB time broadcasts
• Selectable four U.S. time zones (EST, PST, MST, CST)
• Optional Auto DST that advances or retards one hour
• Manual override available if you prefer to disable automatic adjustments

What display information does the large LCD show and how readable is it?

The generous LCD measures 6.2 by 3.7 inches and separates time, indoor temperature, day and date into distinct fields for quick scanning. Characters are high-contrast, making the main time easy to read across a room while supporting details remain visible at a glance.

• Large main time digits for distance legibility
• Separate areas for temperature, day and numerical date
• Switch between 12-hour and 24-hour formats
• Temperature display toggles between °F and °C

Can this clock run without a power outlet and what about low-battery alerts?

The clock runs on three AAA batteries (not included) so you can put it wherever it’s most useful — no cord needed. A low-battery icon appears on the screen to remind you it’s time to replace cells and avoid inaccurate timekeeping due to weak power.

• Battery-operated for flexible wall or tabletop placement
• Low-battery indicator displayed on the LCD
• Simple tab or wall-mount slot for hanging installation
• Quiet operation with no tethering to an outlet

What alarm and customization options are available?

The clock includes a user-settable alarm that toggles on and off with a visible bell icon when enabled. You can choose 12- or 24-hour time format and change temperature units; DST can be left on to switch automatically or turned off if undesired.

• Single alarm with on/off indicator bell icon
• Stop alarm easily by pressing any button
• 12/24-hour display mode linked to alarm time
• DST on/off selection and °F/°C temperature toggle
