Lot Essay

Accompanied by a description of the Astrum watch.

The Astral or Astrum watch was made between 1982 and 1984 in a limited edition of seven examples only, out of which one was fitted with a diamond-set bezel. It is the only pocketwatch known to date showing the entire hemisphere.

The "Astrum" model was designed by Richard Daners, Master watchmaker, craftsman and creator of complicated timepieces at Gübelin in Lucerne from 1952 to 1995.

In 1997 he was awarded the Gaia Prize, initiated in 1993 by the curator and directors of the Musée International d'Horlogerie (MIH) in La Chaux-de-Fonds. This international prize is dedicated to Maurice Ditisheim, an early patron of the museum. It is awarded to those who have advanced horology and promoted the arts, history and culture of timekeeping through their work.
