Timeline NASA and the Omega Speedmaster
1959, April 9
In Washington DC, the American space agency NASA presented the first group of military test pilots selected as astronauts. These men became known as the “Mercury Seven” and immediately became national heroes. June 1962 training photos revealed that three of the astronauts used a privately owned Omega Speedmaster chronograph; US Navy LtCmdr Walter "Wally" Schirra and US Air Force Captains Donald "Deke" Slayton and Leroy "Gordo" Cooper.
1963, October 3
During the 9 hours 13 minutes long Mercury-Atlas 8 mission, astronaut Walter “Wally” Schirra wore his personal Omega Speedmaster CK2998-4 aboard the “Sigma 7” capsule.
His Speedmaster chronograph became the first Omega in space!
1964, May 15
During the 34 hours 19 minutes long Mercury-Atlas 9 mission, astronaut Leroy “Gordo” Cooper was the first to test two wrist watches in space. Aboard the “Faith-7” capsule, Cooper checked the performance of his personal Bulova Accutron Astronaut tuning fork watch with his personal Omega Speedmaster CK2998 chronograph.
1964, October 21
NASA’s Gemini & Flight support procurement office contacted 10 watch brands to inform them about an upcoming competitive tender to supply the space agency with wrist watches for the astronauts of the Gemini space program. Only four watch brands responded and NASA project engineer James Ragan conducted rigorous testing of these time pieces.
1965, March 1
After 4 months of testing, NASA's flight safety office confirmed that only the Omega Speedmaster (reference 105.003) satisfied all flight qualification requirements and the Omega wristwatch could be purchased to be issued to NASA astronauts as government furnished equipment. On March 3, 1965 astronaut John Young was pictured wearing an Omega Speedmaster on a flat link bracelet over his Gemini spacesuit during GT-3 weight and balance tests.
1965, March 23
The two men Gemini III mission marked the first use of officially flight-qualified accepted Omega Speedmaster watches by NASA astronauts. Veteran command pilot Virgil Grissom wore a Speedmaster and an Accutron Astronaut while astronaut John Young wore two Speedmaster chronographs. On the launchpad, astronaut Thomas Stafford assisted with capsule ingress and also wore an Omega Speedmaster (NASA photo 65-H-441).
1965, April 23
NASA purchased the first batch of Omega Speedmaster chronographs consisting of seventeen 105.003 wrist watches. The space agency obtained additional batches in 1966, 1967 and 1968. The latter procurement contained a mix of 105.012 and 145.012 although NASA kept the 105.003 chronographs operational during the entire Apollo program.
1965, June 1
NASA Gemini program office issued its Letter of Certification, officialising the Omega Speedmaster as the only flight-qualified chronograph for Gemini and Apollo programs. These chronographs ran on the calibre 321 movement...
On June 3, 1965 the Gemini IV mission, during which astronauts James McDivitt and Edward White both wore two Speedmasters to keep track of mission events elapsed time, became the highlight of the program as White conducted a 20 minutes long spacewalk.
Regular manual wind Speedmaster chronographs were issued to all subsequent Gemini crews, and worn on another 8 spacewalks, until the end of the program in November 1966.
1968, October
Omega introduced the calibre 861 for the Speedmaster 145.022 and this cam-switched movement progressively replaced the calibre 321 column-wheel movement. Based on astronauts’ feedback NASA and Omega started to work on the ultimate space watch using the codename Alaska. This research lead to an innovative Speedmaster cased in pure titanium protected by an extra aluminium outer case and resulted in the development of the X-33 Speedmaster in 1997.
1969, July 20
Apollo 11 became a historic mission as it landed the first two astronauts on the Moon.
Commander Neil Armstrong was the first to set foot on the lunar surface but he didn’t wear his NASA-issued Speedmaster 105.012-65 as it was left inside the cockpit of the “Eagle” Lunar Module as a backup for the malfunctioning electronic timer. Apollo 11 Lunar Module Pilot Edwin “Buzz” Aldrin was the first to wear an Omega Speedmaster during a lunar EVA (spacewalk). Armstrong and Aldrin conducted a 2 hours 31 minutes moonwalk and spent of total of 21 hours 36 minutes in Mare Tranquillitatis before rejoining Command Module Pilot Michael Collins aboard “Columbia” in lunar orbit.
Total mission time was 8 days 3 hours.
1970, April 16
Apollo 13 became a historic mission as it encountered an oxygen tank explosion crippling the Command & Service Module “Odyssey” and aborting the lunar landing. Commander James Lovell, Lunar Module Pilot Fred Haise and Command Module Pilot Jack Swigert evacuated into the Lunar Module “Aquarius” which became a lifeboat as its engine was used to make a series of burns to bring the spacecraft back to Earth. The last of these LM burns had to be timed with the onboard interval timer, which failed so Jack Swigert resulted in the need to use his Speedmaster chronograph instead. The crew performed the 14 seconds burn to correct the re-entry into Earth’s atmosphere.
Total mission time was 5 days 22 hours.
1972, December 19
Apollo 17 became the final mission to land men on the Moon. Commander Eugene Cernan and Lunar Module Pilot geologist Harrison “Jack” Schmitt conducted 22 hours moonwalk EVA time and spent a total of 75 hours in Taurus-Littrow before rejoining Command Module Pilot Ronald Evans in lunar orbit. The heat flow experiment aboard “America” was equipped with a Speedmaster 145.022-69 chronograph, the sole calibre 861 to fly on an Apollo lunar mission.
Total mission time was 12 days 13 hours.
1975, July 17
The Apollo-Soyuz Test Project (ASTP) marked the end of the space race as three American astronauts joined two Russian cosmonauts in Earth orbit. The Soyuz spacecraft connected with an Apollo Command & Service Module equipped with a special docking module. Both mission commanders, Thomas Stafford and Alexei Leonov exchanged the first international handshake in space. Both crews accounted for a total of 11 Omega Speedmaster chronographs flown during the mission, conducting joint activities as the craft remained docked for 44 hours. US crew total mission time was 9 days 1 hour.
1976, March
To commemorate the successful Apollo-Soyuz mission, Omega distributor De Marchi requested a special Speedmaster 145.022 series for the Italian market.
1977, October 9 and December 10
The Omega Alaska project chronographs made it to the Russian space program as both the Soyuz 25 and Soyuz 26 crews were photographed wearing the red distinctive outer cases over the left forearm of their Sokol spacesuits. Soyuz 25 was unable to dock with the Salyut-6 space station, so Soyuz 26 became the first long-stay crew aboard the Russian space station. It was fitting that these watches should be worn by Russians, given that the Titanium was sourced in the Soviet Union.
1981, November 12
Astronauts Joe Engle and Richard Truly were the first to wear the Omega radial dial Speedmaster Alaska III chronograph aboard space shuttle mission STS-2 as the Speedmaster was requalified for the space transportation system program.
1983, April 7
Astronauts Story Musgrave and Donald Peterson performed the first space shuttle era EVA (spacewalk) aboard Challenger during the STS-6 mission. Omega Speedmasters were attached to the sewn-in pockets in the outer garment layer of their right hand gloves, covered by a Velcro flap. This was in marked contrast to Russian cosmonauts who continued to strap their Speedmaster chronographs directly to the forearms of their Orlan space suits.
1990, December 2
The Soyuz TM-11 crew took a box containing 10 Omega Speedmaster chronographs up to the Russian space station Mir. During 90 days, these watches were checked and used in the low-gravity environment of the space station before being returned to Earth in March 1991.
1993, July 1
The Soyuz TM-17 crew took a set of 35 Omega Speedmaster chronographs, among which 7 in yellow gold, up to the Russian space station Mir. After a year in space, these chronographs were returned to Earth on July 9, 1994 and were sold in July 1995. Each watch had a special caseback referring to their time aboard the Mir space station.
1998, January 23
The seven astronauts aboard space shuttle Endeavour were the first to wear the new Omega X-33 Speedmaster Professional during the STS-89 mission to the Russian space station Mir. On March 28, 1998 NASA astronaut Andrew Thomas together with Russian cosmonauts Musabayev and Budarin presented the X-33 watches during a live television broadcast from the space station.
2003,
Astronaut Donald Pettit performed the first watch repair in space as he refastened the crown onto his X-33 Speedmaster Professional chronograph.
2014, December 15
European astronaut Jean-François Clervoy patented the X-33 Skywalker functions for the European Space Agency (ESA). In addition to the previous X-33 model, the Skywalker featured additional countdown features such as a phase elapsed time function and mission elapsed time alarms so the cosmonaut/astronaut could more easily keep track of the time leading up to, and since certain mission events. Having passed all ESA tests, the X-33 Speedmaster Skywalker became standard equipment for all European astronauts.
2019, July 16
Omega commemorates the 50th anniversary of the Apollo 11 moon landing with a limited edition of the manual wind Speedmaster chronograph.
