Hello everyone, I got this beautiful clock from someone who couldn't do anything with it anymore. I've had this clock for (about) a year now. He has always worked and from one day to the next which he no longer does. I assumed the battery was dead. I then neatly opened the back by the four screws loosen with the correct bit. You only see a plate with the vibrating membrane of the alarm clock??? You also see four screws again that I also unscrewed and then the glass frame at the front comes loose and then the dial is completely exposed. I immediately put it back neatly because I don't know where the battery is. And now I ask myself the question, does it have a battery, or how does this clock work. I hope someone can help me, because I think this is a beautiful piece and I think it's a shame that he no longer does.
