The [[Weightlessness|zero-gravity]] environment and other extreme conditions encountered by [[astronaut]]s in [[Outer space|space]] require the use of specially tested watches.

The first-ever watch to be sent into space was a Russian "[[Pobeda (watch)|Pobeda]]" watch from the [[Petrodvorets Watch Factory]]. It was sent on a single orbit flight on the spaceship [[Korabl-Sputnik 4]] on 9 March 1961. The watch had been attached without authorisation to the wrist of Chernuchka, a dog that successfully did exactly the same trip as [[Yuri Gagarin]], with exactly the same rocket and equipment, just a month before Gagarin's flight.<ref>{{cite book |title=Animals in Space: From Research Rockets to the Space Shuttle |edition=illustrated |first1=Colin |last1=Burgess |first2=Chris |last2=Dubbs |publisher=Springer Science & Business Media |year=2007 |isbn=978-0-387-49678-8 |page=213 |url=https://books.google.com/books?id=xSdHVIpsrKkC}} [https://books.google.com/books?id=xSdHVIpsrKkC&pg=PA213 Extract of page 213]</ref>

On 12 April 1961, Gagarin wore a Shturmanskie (a transliteration of {{lang|ru|Штурманские}} which actually means "navigator's") wristwatch during his historic first flight into space. The Shturmanskie was manufactured at the [[Poljot|First Moscow Factory]]. Since 1964, the watches of the First Moscow Factory have been marked by the trademark "{{lang|ru|Полёт}}", transliterated as "POLJOT", which means "flight" in [[Russian language|Russian]] and is a tribute to the many space trips its watches have accomplished. In the late 1970s, [[Poljot]] launched a new [[Chronometer watch|chrono]] movement, the 3133. With a 23 jewel movement and manual winding (43 hours), it was a modified Russian version of the [[Switzerland|Swiss]] [[Valjoux]] 7734 of the early 1970s. Poljot 3133 were taken into space by astronauts from Russia, France, Germany and [[Ukraine]]. On the arm of [[Valeriy Polyakov]], a Poljot 3133 chronograph movement-based watch set a space [[World record|record]] for the longest space flight in history.<ref>{{cite web |url=http://www.netgrafik.ch/russian_space_watches.htm |title=Russian Space Watches History |publisher=Netgrafik.ch |access-date=27 May 2012 |archive-date=12 December 2020 |archive-url=https://web.archive.org/web/20201212073856/http://www.netgrafik.ch/russian_space_watches.htm |url-status=live }}</ref>

Through the 1960s, a large range of watches was tested for durability and precision under extreme [[temperature]] changes and vibrations. The [[Omega Speedmaster Professional]] was selected by [[NASA]], the U.S. space agency, and it is mostly known thanks to astronaut [[Buzz Aldrin]] who wore it during the 1969 [[Apollo 11]] Moon landing. [[TAG Heuer|Heuer]] became the first Swiss watch in space thanks to a Heuer Stopwatch, worn by [[John Glenn]] in 1962 when he piloted the ''[[Friendship 7]]'' on the first crewed U.S. orbital mission. The [[Breitling Navitimer]] Cosmonaute was designed with a [[24-hour analog dial]] to avoid confusion between AM and PM, which are meaningless in space. It was first worn in space by U.S. astronaut [[Scott Carpenter]] on 24 May 1962 in the ''[[Aurora 7]]'' Mercury capsule.<ref>{{cite web|url=https://www.breitling.com/us-en/watches/navitimer/|title=Navitimer, the aviator favourite watch|work=[[Breitling SA|Breitling]]|access-date=17 January 2007|archive-date=4 April 2018|archive-url=https://web.archive.org/web/20180404200807/https://www.breitling.com/us-en/watches/navitimer/|url-status=live}}</ref>

Since 1994 [[Fortis Uhren AG|Fortis]] is the exclusive supplier for crewed space missions authorized by the [[Russian Federal Space Agency]].

At [[BaselWorld]], 2008, [[Seiko]] announced the creation of the first watch ever designed specifically for a space walk, Spring Drive Spacewalk. [[Timex Datalink]] is flight certified by NASA for space missions and is one of the watches qualified by NASA for space travel. The [[Casio]] [[G-Shock]] DW-5600C and 5600E, DW 6900, and DW 5900 are Flight-Qualified for NASA space travel.<ref name="NASA 5-8 Article">{{cite web |url=http://www.nasaexplores.com/show2_5_8a.php?id=02-024&gl=58 |archive-url=https://archive.today/20061114025319/http://www.nasaexplores.com/show2_5_8a.php?id=02-024&gl=58 |url-status=dead |archive-date=14 November 2006 |date=14 November 2006 |access-date=23 October 2011 |df=dmy-all | title=NASAexplores 5-8 Article: What Time is It? }}</ref><ref name="NASA 9-12">{{cite web |url=http://www.nasaexplores.com/search_nav_9_12.php?id=02-024&gl=912 |archive-url=https://archive.today/20080304191551/http://www.nasaexplores.com/search_nav_9_12.php?id=02-024&gl=912 |url-status=dead |archive-date=4 March 2008 |date=4 March 2008 |access-date=23 October 2011 |df=dmy-all | title=NASAexplores - Express Lessons and Online Resources }}</ref>

Various Timex Datalink models were used both by cosmonauts and astronauts.
