This is the iconic 1950's Kigu flying saucer compact. There were 3 types made - the one with the musical movement, this one without and a plain gilt one. The enamelled one came in different colours - but the deep blue was the most common colour. There was a lot of interest in space travel in the 1950's. There is a full description of the compact on my web site - www.gillianhorsup.com - reference 2616 b133/36 price £295 together with a condition report.
