The exterior of The Planetarium is a blue canvas with white straps. The case is secured with hook and loop, similar to the hook and loop on the MoonSwatch straps. Fun fact: The hook and loop is a detail of interest as it is an homage to the original Speedmaster Moonwatch straps which were 2 ft of hook and loop so astronauts could wrap them around their spacesuits. The case measures: 18in x 13in x 4in (45.72cm x 33.02cm x 10.16cm).
Whether you place the watches in order of distance from the sun (Sun, Mercury, Venus, Earth, (Moon), Mars, Jupiter, Saturn, Uranus, Neptune Pluto) or any other way, there's no bad combination as the vibrant colors pop off the neutral background and look amazing when presented together.
