The special feature of the WT 8990 is a small integrated sensor that causes the second hand to stop moving in darkness, so you won't be disturbed by the ticking sound at night. The display of the current time remains unaffected by this pause and continues to show you the exact time reliably. The WT 8990 is a radio-controlled wall clock in a classic station design. It is a high-quality device with a metal frame and glass cover. The diameter is 30 cm, making the dial easily readable even from a distance. Thanks to DCF77 signal reception, the clock automatically adjusts for both winter and summer time, saving you the hassle of changing the time manually.
