To try and improve the calculation of the train which allowed for an error of 0.8 seconds per year Dr. Daniels contacted a friend at Cambridge University to ask if they knew of a mathematician interested in watches. He got a response almost immediately and extraordinarily enough the mathematicians name was Professor Daniels. The professor was able to calculate a better ratio of 0.28 seconds per day, which Dr. Daniels was very happy with.
Dr. Daniels used to say to people, ‘when you are on your package tour to Mars you need a watch like this, and when using the telephone for long distance calls you could switch the chronograph into sidereal time to cut your bills by 3.555 minutes per day’.
Originally the watch had been referred to as the Daniels squared (2) because of the assistance he received from Professor Henry Daniels but Dr. Daniels did not think this was good enough so named it the ‘Space Travellers’ watch in honour of the American landing on the moon which was the greatest space exploratory journey of the century.
Sotheby's sold the first Space Travellers' watch on 17th November 1988 in Geneva for 220,000 CHF.
