Sharp Atomic Alarm Clock with Color Display — Dual Alarms, Calendar & Auto‑Set WWVB, Adjustable Brightness

The Sharp Atomic Alarm Clock is an auto‑setting bedside clock with a vivid color display, dual alarms, calendar and WWVB time synchronization for second‑accurate timekeeping.

Designed for people who want a worry‑free clock that always shows the correct time, this Sharp bedside clock receives the national WWVB atomic signal to set itself each day. It combines an easy‑to-read color calendar and day‑of‑week display with two programmable alarms and an adjustable brightness control so the display fits any bedroom lighting. A battery backup protects your settings during power interruptions, and the top‑mounted snooze/dimmer control makes quick adjustments effortless.

How does the atomic synchronization keep time accurate?

The Sharp Atomic Alarm Clock includes a receiver that listens for the WWVB radio signal from NIST, allowing it to update daily and correct any drift. When the signal is found, the clock sets itself automatically to the precise time; during the signal search the screen may briefly go dark.

• Daily automatic updates from the WWVB time broadcast.
• Accurate to within one second once synchronized.
• Automatic reset for daylight saving changes where applicable.
• Screen relights after the signal is acquired.

What display and alarm features will I see each morning?

The color display presents time, calendar date and day of the week at a glance, with a top snooze/dimmer switch to tailor brightness to your room. Dual alarms let two people set separate wake times or create weekday/weekend schedules without reprogramming.

• Full color calendar and day‑of‑week readout for fast reference.
• Snooze button combined with a dimmer for one‑touch control.
• Two independent alarms for different schedules.
• Always‑on display once atomic signal is locked in.

What happens if the power goes out or the signal is weak?

A pair of AAA batteries (not included) provide a no‑worry backup to preserve the time and alarm settings during outages; however, the display will not be lit while running on backup power. If the WWVB signal is momentarily unavailable, the clock will keep running on its internal time until the next successful update.

• Uses 2 x AAA batteries for backup (batteries sold separately).
• Settings and alarms are retained during power loss.
• Display remains dark on battery backup to conserve power.
• Continues normal operation and display once power restores and signal is found.

How easy is it to set and use day‑to‑day?

Setup is minimal because the clock auto‑sets itself; day‑to‑day operation is simplified by the top‑mounted snooze/dimmer and clearly labeled controls. The dual alarm function is straightforward to program for two users or different weekday/weekend routines.

• Automatic initial setup reduces manual configuration.
• Top snooze/dimmer switch for one‑hand adjustments.
• Clear calendar and day display to avoid date confusion.
• Dual alarms for flexible scheduling without extra devices.

Who is this for: The Sharp Atomic Alarm Clock suits anyone who wants a reliable, low‑maintenance bedside clock—commuters, shift workers, couples with different wake times, and anyone who prefers an always‑accurate timepiece with an easy‑to‑read color calendar. It’s especially useful for users who want automatic time updates and simple, one‑touch brightness controls without smart device complexity.
