Footnotes

  • Sven Andersen is a Danish watchmaker living in Switzerland. He co-founded the AHCI (Academie Horlogere des Createurs Independants) in 1985.

    An expert in lunar calendars, the idea for the Orbita Lunae automatic came to Andersen while designing a Jewish calendar for Alain Silberstein in 1995. The disc under the dial carries two gold moons and two blue circles. The disc rotates at around half the speed of the dial, compensating for the 10 days difference between the lunar and solar year. Andersen adds 2 1/2 days every two months or 15 days a year. The adjustment of the calendar five times a year (in months of fewer that 31 days) removes the five surplus days.
