Swatch x OMEGA MoonSwatch: Mission to EarthPhase (SO33M700)

The MoonSwatch Mission to EarthPhase is the most technically ambitious model in the collection outside the Snoopy editions. It combines a chronograph with two additional complications — a moonphase display at 2 o'clock and a patented earth phase indicator at 10 o'clock — all within the same 42mm Bioceramic case. No other MoonSwatch offers this much functionality.

The light grey case and grain-textured dial give the EarthPhase a calm, balanced tone that represents Earth as seen from orbit. Under UV light, the earth phase display at 10 o'clock reveals coloured continents and glowing blue oceans — a hidden feature that rewards closer inspection. On the caseback, an engraved moon with Neil Armstrong's footprint connects the model back to the Speedmaster's Apollo heritage.

Every MoonSwatch sold by MGB Watches is authentic, directly sourced and inspected before dispatch. Ships with tracked UK and international delivery. Not sure if this is the right model for you? See how it compares to the Mission to the Moon → or the Snoopy Moonphase editions →.
