4" Twin Bell Alarm Clock Green 4.5 x 3.81 x 6.5 in

Compact Green Twin-Bell Alarm Clock

This 4.5 by 3.81 by 6.5 inch analog clock uses a traditional twin-bell mechanism to produce a loud mechanical ring suited for deep sleepers. Its green metal case and black Arabic numerals fit a range of bedroom decors. A rear-mounted white button activates a temporary backlight for checking the time in darkness without a permanent glow. The unit runs on a single AA battery, avoiding mains wiring.

Check power and placement before ordering

The clock requires one AA cell which is not supplied, so have a fresh battery ready. Verify that the 6.5 inch height and 3.81 inch width suit your nightstand or shelf space. Ensure you are comfortable with a purely mechanical alarm that cannot be silenced by a snooze function and that the analog hands meet your readability needs. The movement is silent-sweep, so there is no audible tick.

Thermals noise and power draw

Battery operation means the clock generates no measurable heat and draws negligible current during normal timekeeping. The silent-sweep movement produces no ticking sound, leaving only the intentional alarm ring when triggered. Backlight use is momentary and button-held, so its impact on battery life is minimal. No fan, transformer or active electronics are present to create background noise or warmth.
