Vintage \"Swiza Electric\" Alarm Clock For Sale

Vintage \"Swiza Electric\" Alarm Clock. I would assume this is from the 1970s. This clock measures 11cm x 7cm x 4cm. It weighs 525 grammes. The dial reads \"Swiza Electric Swiss Made\". The case is in good condition with no dings or dents. It could do with clean. The glass has minor scuffs. The caseback reads \"2862\" The clock winds, sets and works properly. The alarm works, but doesn\'t set. The clock is some kind of hybrid. It has a mechanical movement with possibly a battery back-up? I have not been into it and cannot seem to get the \'electric\' part going with a battery. Sold for repair.
