Omega x Swatch is a collaboration between Swatch and Omega. Swatch owns Omega, so it makes sense that they were able to accomplish this. The watches closely resemble Omega SpeedMaster watches. The watches are Bioceramic, which is a mixture of ceramic and plastic materials. The watches come of very well-designed VELCRO straps and are quartz watches that are battery-powered. At launch, Swatch unveiled the following watches:

Mission to the Sun
Mission to Mercury
Mission to Venus
Mission to Earth
Mission to the Moon
Mission to Mars
Mission to Jupiter
Mission to Saturn
Mission to Uranus
Mission to Neptune
Mission to Pluto
