We are frequently asked which Speedmaster models have been worn on the Moon. Some way or another, individuals think the type 861 Speedmaster Professional (145.022) was one of them, yet this isn’t correct.

In 1962, NASA space explorer Walter “Wally” Schirra wore his Omega Speedmaster CK2998 in space. Accordingly, the 2012 presentation of the First Omega in Space watch(es) depended working on it of the first CK2998. Be that as it may, Schirra’s watch was exclusive and had nothing to do with the chronographs formally selected by NASA. It wasn’t until 1964 that NASA mentioned brands to give a statement to a wristwatch with a chronograph work. Just four brands reacted to that demand: Omega, Rolex, Longines-Wittnauer, and Hamilton (you can find out about them here ). Rolex with their reference 6238 chronograph, Longines – Wittnauer with their 235T reference, and Hamilton (whose improvement group probably been sleeping at the hour of the solicitation) with a pocket watch. Omega sent the Speedmaster, reference 105.003. We shrouded the choice cycle inside and out in this article on Fratello .

Three Speedmaster References Worn on the Moon

In complete, just three distinctive Speedmaster references were utilized on the Moon by the NASA space explorers. A few more Omega Speedmaster references have been close to the moon or in space, however not on the moon. The Speedmaster that was tried by NASA and qualified for all maintained space missions is reference 105.003.


This model, with straight-carries and no crown watches, is regularly additionally alluded to as the pre-Professional, or “Ed White” (presently offering its moniker to Omega’s most recent delivery ). Not on the grounds that space explorer Ed White was the first to utilize it in space (that honor has a place with Grissom and Young, who did so half a month after the authority capability date during the Gemini III mission), yet he was the first to utilize it during a spacewalk (as a feature of the Gemini IV mission). Presented beneath is a 105.003 from the Omega Museum in Bienne, you may see that the enormous chronograph second hand is a later make. The watch likewise doesn’t highlight the popular and pursued DON bezel. Parts like these are frequently supplanted during their lifetime because of harm. In the above picture, the right second hand and bezel can be seen.


The 105.012 is the main Omega Speedmaster Professional. This reference was presented before the watch was qualified by NASA, and furthermore the ‘Professional’ phrasing on the dial was before that time, so it has nothing to do with the way that NASA chose to utilize the Speedmaster as their authority chronograph. For the Apollo space travelers, Omega transported the Speedmaster 105.012 to NASA. It had an alternate case shape, presently with the crown and pushers recessed for the situation band, yet it didn’t should be tried (once more). The test work (and the aftereffects) of the Speedmaster 105.003 were fine, and this refreshed model would finish those assessments too. This Speedmaster reference was worn by both Neil Armstrong and Edwin ‘Buzz’ Aldrin and, consequently, turned into the main Speedmaster worn on the moon. Rumors from far and wide suggest that Armstrong left his Speedmaster Professional 105.012 in the module, as the (Bulova) load up clock quit working properly.


In 1967, Omega presented the replacement of the 105.012, named the 145.012. The primary distinction from the 105.012 is the pusher development, which was notably enhanced the 145.012. There’s likewise another distinction with prior variants of the 105.012, as those were conveyed with twofold slant case back. The 145.012 was worn by Michael Collins during the Apollo XI mission, yet since Collins stayed in the command module, it didn’t make it to the outside of the moon on that event. The 145.012 had its day in the sun, notwithstanding, and was utilized on the moon during later missions.

Strangely, the 105.003 kept on being utilized by space explorers notwithstanding the conveyance of the refreshed 105.012 and 145.012 references. This was on the grounds that NASA actually had the 105.003 in their ownership since the acquisition of 1964. This is the reason each of the three references were utilized on the moon somewhere in the range of 1969 and 1972. Albeit the Speedmaster Professional 145.022 was presented in 1968, it was never utilized on the moon. That specific watch was just qualified in 1978, for the Space Shuttle program. The case back of the 145.022 is the place where the “Flight Qualified by NASA for all monitored space missions” text can be found.

Some Thoughts

I am certain that the vast majority of the data above was at that point known to the lovers out there, however we actually get a ton of inquiries from individuals who have one of these three references and need to know whether theirs was utilized on the moon. Significantly more regularly, we get whether or not the Speedmaster Professional 145.022 with type 861 was utilized on the moon. So I trust this short article underlines again which accurate references were utilized on the moon. Every one of them were controlled by type 321 developments. A critical development, as a result of its magnificence as well as because of its part on the wrist of the Apollo space explorers. In 1968, Omega began utilizing the type 861 development for two principle reasons: Higher precision because of a higher ticking number and creation costs. Type 861 was somewhat easier and, subsequently, less expensive to deliver. The Lémania 2310 development, like Omega type 321, was subsequently utilized by Patek Philippe and Breguet  for their chronographs. Type 861 was supplanted by type 1861 out of 1996/1997 can in any case be found in today’s Omega Speedmaster Professional and Speedmaster CK2998 models, for instance. Omega’s new type 3861 ( Master Chronometer certified ) will probably discover its way into the Moonwatch sooner or later. Omega’s once again introduced type 321 is a smidgen more restrictive, and can be found in the Speedmaster Platinum Moonwatch from 2019 and soon in the new steel Speedmaster “Ed White.”

That said, on the off chance that you need to have a watch that is (almost) indistinguishable from the ones worn on the moon, the type 321 fueled references are the ones to focus on. Study the historical backdrop of Omega .
