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.
