Vintage Swiza Mignon Aquarium Alarm Clock I would assume this is from the 1950s/60s. This clock measures 15cm x 11cm x 4.5cm. It weighs 639 grammes. The dial reads "Swiza Mignon 8 7 Jewels Swiss". The perspex case has lots of minor scuffs and scratches to the front. They are hard to pick up with a camera, but they are there. The rear reads "8 Days Swiss Made". The regulator cover is missing The clock winds, sets and works properly. The alarm also works properly.
