Swartzwald - black and white is our classic kit with the traditional Black Forest cuckoo clock motif for grinding. First, color in the fields as you wish. You will then need about an hour to carefully assemble the watch and put it on the movement. Then it reliably shows the time, oscillates like an original cuckoo clock and can be connected to your mobile phone via Bluetooth and not only does the cuckoo call sound, but every sound or music from the loudspeaker in the clock that you want.
