The watch, described by Daniels as"the kind of watch you would need on your package tour to Mars," was one of only 23 pocket timepieces handmade by the master watchmaker.
Inspired by the 1969 US moon landing, the Space Traveller was built to show both solar and sidereal time -- respectively, time reckoned according to the relative positions of the earth and the sun, and the relative positions of the earth and the stars -- equation of time , and phases of the moon.Sotheby's
"Daniels was determined that his watch would be one that could be of theoretical use to an astronaut, he therefore set out to devise a watch that displayed, simultaneously, both mean-solar and sidereal time," Sotheby's said. The watch, which was completed in 1982, also features Daniels' independent double wheel escapement, which the horologist invented in 1974.
