The page inexplicably contains the word ''astrolabium''. By [[Jan Collaert II]]. [[Museum Plantin-Moretus]], [[Antwerp]], Belgium.]]

Mechanical [[astronomical clock]]s were initially influenced by the astrolabe; they could be seen in many ways as clockwork astrolabes designed to produce a continual display of the current position of the sun, stars, and planets. For example, [[Richard of Wallingford]]'s clock ({{circa|1330}}) consisted essentially of a star map rotating behind a fixed rete, similar to that of an astrolabe.{{sfn|North| 2005}}

Many astronomical clocks use an astrolabe-style display, such as the famous [[Prague Orloj|clock at Prague]], adopting a stereographic projection (see below) of the ecliptic plane. In recent times, astrolabe watches have become popular. For example, Swiss watchmaker [[Ludwig Oechslin]] designed and built an astrolabe wristwatch in conjunction with [[Ulysse Nardin]] in 1985.<ref>{{cite web |url=http://www.ulysse-nardin.ch/en/swiss_watch_manufacturer/Collection/Archive/Astrolabium_G._Galilei.html |url-status=dead |archive-url=https://web.archive.org/web/20110102024043/http://www.ulysse-nardin.ch/en/swiss_watch_manufacturer/Collection/Archive/Astrolabium_G._Galilei.html |archive-date=2 January 2011 |title=Astrolabium G.
