The honour of being the first watch on this site goes to my old favourite, the Ulysse Nardin Astrolabium Galileo Galilei.

One of three watches in Ulysse Nardin’s “Trilogy of Time” series, the Astrolabium was introduced to the world at the 1985 Basle Watch Fair.

Four years later, the Astrolabium made it into the Guinness Book of Records. Its achievement was to be the first watch to offer certain astronomical features. It gives the position of the sun, moon and stars as defined by altitude and azimuth, as well as the zodiac sign at any given time. It also indicates solar and lunar elipse, sunrise, sunset, moonrise, moonset, moon-phase and such other things of great interest to astronomers.
