Königswerk SZ-836 digital clock 6.5 in black

Compact 6.5-inch bedroom clock

The Königswerk SZ-836 is a plug-in digital alarm clock with a black finish and large numerals readable from across the room. It suits anyone who wants a clear time display on a bedside table, desk or office surface without a bright glow at night. Battery backup with three AAA cells keeps the settings and alarm active during power cuts, though an adapter is required for continuous operation.

Three-level dimmer and silent running

Brightness adjusts across three fixed levels so the display stays visible in daylight yet stays dim enough not to disturb sleep. The unit has no fan or moving parts, so it runs silently and draws only the minimal power needed for the LED display and temperature sensor. A simple wall adapter keeps it running while the batteries sit idle until a mains failure occurs.

Replaces basic plug-in clocks lacking backup

This model upgrades from simple mains-only clocks that lose time and alarms during outages. The jump is worth it if you need dual independent alarms with weekday, weekend or daily schedules plus a snooze function. Buyers who want projection, radio, smart-home connectivity or a larger display will not find those features here.
