Apolar is Behrens' 'Earth-Moon' watch: a globe at the centre turns once in about 24 hours while a small moon orbits it every 28 days, showing how the two bodies move. It was nominated for Calendar and Astronomy at the 2020 GPHG. A Sellita SW200 automatic base drives the system in a 42 mm 316L steel case with anti-reflective sapphire and a transparent caseback.
