WallarGe Digital Atomic Wall Clock 8.5" — Indoor & Outdoor Temperature, WWVB Auto-Sync

The WallarGe 8.5" Digital Atomic Clock is a battery-powered wall clock that automatically syncs to WWVB time and shows indoor and outdoor temperatures from a wireless sensor.

This compact, easy-to-read digital clock combines precise atomic timekeeping with a remote outdoor sensor so you can see current time, seconds, day, date, and both indoor and outdoor temperatures at a glance. It supports four U.S. time zones (EST, CST, MST, PST), automatic daylight saving adjustments, and switchable 12/24-hour and °F/°C displays. Designed for everyday rooms, garages, and porches (sensor within 330 feet, out of direct sun or rain), the unit runs on standard batteries for convenient placement without cords.

How does the WallarGe clock keep time so accurately?

The clock contains an atomic receiver that picks up the WWVB radio signal to set and correct the time automatically each night. That eliminates manual resetting for drift and keeps the display synchronized to national time standards. You can select the appropriate U.S. time zone and enable or disable Daylight Saving Time as needed.

• Automatic nightly WWVB synchronization for precise time
• Four selectable zones: EST, CST, MST, PST
• Auto DST option to move clocks forward or back
• 12/24-hour mode to suit personal preference

What temperature and sensor features does it offer?

The clock displays both indoor temperature and readings sent from a wireless outdoor sensor, making it simple to compare indoor comfort with outdoor conditions. The sensor transmits up to about 330 feet in clear line-of-sight; place it away from direct sunlight and precipitation for reliable readings. Temperature units can be switched between Fahrenheit and Celsius on the clock’s back panel.

• Indoor and wireless outdoor temperature readouts on one screen
• Sensor transmission up to 330 feet (typical unobstructed range)
• Fahrenheit and Celsius selectable via rear button
• Low-battery icons flash on screen for both clock and sensor

What power and installation should I plan for?

Both clock and sensor run on non-rechargeable batteries—three AAA for the clock and two AA for the sensor—so no wall outlet is required. The clock lacks a backlight, which preserves battery life and suits well-lit rooms or daytime use; low-battery indicators notify when to replace cells. Mounting is straightforward with a rear keyhole slot for hanging or freestanding placement on a shelf.

• Clock: 3 x AAA batteries (not included)
• Sensor: 2 x AA batteries (not included)
• No backlight to extend battery life
• Simple wall hang or shelf placement options

How readable and informative is the display?

The 8.5-inch screen shows time with prominent, bold digits and seconds centered for quick reference, while the lower section lists indoor/outdoor temperatures, day, and date. Icons indicate active alarm and DST status so you can confirm settings instantly. The screen layout is optimized for common viewing distances in kitchens, entryways, and offices.

• Large central time digits with seconds
• Bottom row displays temps, day, and date
• Alarm and DST icons visibly displayed
• Clear contrast for easy reading from several feet away

Who is this for: The WallarGe 8.5" Digital Atomic Clock suits homeowners and renters who want reliable, low-maintenance timekeeping and simple indoor/outdoor temperature tracking without running cords. It’s a practical choice for kitchens, garages, workshops, porches (sensor protected), offices, and small business spaces where automatic WWVB synchronization and battery operation are valuable. If you need a plug-free, precise clock with clear digits and a wireless temperature sensor, this model fits that need.
