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 reliably show the exact time. 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. With a diameter of 30 cm, the clock face is easily readable even from a distance. Thanks to the DCF77 signal reception, the clock automatically adjusts for both winter and summer time, saving you the hassle of changing the time manually.
