TL;DR: The Omega Speedmaster was born in 1957 as a racing chronograph, became the first watch worn on the Moon in 1969, and has evolved through five major calibre generations to the current METAS-certified Calibre 3861. Nearly 70 years later, it remains one of the most significant timepieces ever made — and one of the few luxury watches you can buy under $7,500 with genuine space-programme heritage.

The Birth of the Speedmaster (1957)
The Omega Speedmaster was never meant for space. When it debuted in 1957 as reference CK2915, it was a motorsport chronograph — one of three professional watches Omega launched that year alongside the Seamaster 300 and the Railmaster. The name “Speedmaster” referred to its tachymeter bezel, a tool for calculating speed over a measured distance, and its target market was racing drivers, not astronauts.
What made the CK2915 special was its engineering. At 39mm, it packed the legendary Calibre 321 — a column-wheel chronograph movement derived from the Lemania 2310 that would become one of the most celebrated movements in watchmaking history. The dial featured broad arrow hands, applied hour markers, and a black tachymeter scale on the bezel. It was water-resistant to 60 metres and shock-protected — serious specifications for 1957.
The original CK2915 went through three sub-references (CK2915-1, -2, and -3) between 1957 and 1959, with subtle dial and bezel changes. Today, these first-generation Speedmasters are among the most valuable Omega watches in existence, with auction prices routinely exceeding $300,000 for examples in good condition.
How NASA Chose the Speedmaster
The Speedmaster’s path to the Moon began almost by accident. In 1962, astronaut Wally Schirra wore his personal Speedmaster CK2998 during the Mercury-Atlas 8 mission, making it the first Omega in space. NASA took notice — not because of marketing, but because astronauts were already choosing the watch themselves.
In 1964, NASA began formally testing chronographs for the Gemini programme. They sent identical requests to several watch brands, including Omega, Rolex, and Longines-Wittnauer. The watches were subjected to brutal qualification tests designed to simulate spaceflight conditions: extreme temperatures (from -18C to 93C), vacuum, humidity, shock, vibration, and high acceleration up to 12G.
Only the Omega Speedmaster — specifically reference ST 105.003 — passed every test. The Rolex submitted reportedly had its crystal pop off during the humidity test, and the Longines-Wittnauer failed the temperature extremes. Omega won not through lobbying or sponsorship, but through pure engineering performance. In March 1965, NASA officially designated the Speedmaster as “Flight Qualified for All Manned Space Missions.”
That same year, astronaut Ed White wore a Speedmaster ST 105.003 during America’s first spacewalk on Gemini 4, cementing the watch’s association with human spaceflight. The image of White floating in space with the Speedmaster strapped to the outside of his suit became one of the most famous photographs in watch history.
The Moon Landing and Apollo Era
On July 20, 1969, the Speedmaster earned its most famous title. Both Neil Armstrong and Buzz Aldrin had been issued Speedmaster reference 105.012 models for the Apollo 11 mission. Armstrong left his watch inside the Lunar Module as a backup timing device after the onboard electronic timer malfunctioned — so it was Aldrin’s Speedmaster that became the first watch worn on the surface of the Moon.
The Speedmaster went on to fly on every subsequent Apollo mission. During Apollo 13 in 1970, astronaut Jack Swigert used his Speedmaster to time the critical 14-second engine burn that corrected the spacecraft’s re-entry angle after the service module explosion — a moment that may have saved three lives. Omega received NASA’s Silver Snoopy Award for its role in the mission’s survival, an honour the brand has since commemorated with limited-edition Speedmaster models that command significant premiums on the secondary market.
Between 1969 and 1972, six Apollo missions successfully landed on the Moon, and every one carried Speedmasters. No other watch brand has ever been part of a lunar surface mission.
Movement Evolution: Calibre 321 to 3861
The Speedmaster’s heart has changed four times across its history, and each transition tells a story about the balance between heritage and progress.
Calibre 321 (1957-1968)
The original. A column-wheel chronograph based on the Lemania 2310, the Cal. 321 is considered by collectors to be the finest movement ever fitted to a Speedmaster. Its operation is smooth and precise, with a satisfying tactile click to the pushers. After discontinuing it in 1968, Omega brought back a faithful reconstruction in 2019 for limited-edition Speedmaster models priced above $14,000.
Calibre 861 (1968-1996)
The 861 replaced the 321 with a cam-lever chronograph mechanism that was cheaper to produce and service while maintaining high accuracy. It powered the Speedmaster through the later Apollo missions, Skylab, and the Apollo-Soyuz programme. The 861 is the movement most strongly associated with the Moonwatch.
Calibre 1861 (1996-2021)
An incremental upgrade to the 861 with improved finishing and rhodium plating. Functionally identical to its predecessor, the 1861 kept the manual-winding, hand-wound character that Speedmaster purists value. It powered the Moonwatch Professional for 25 years.
Calibre 3861 (2021-Present)
The most significant movement change since 1968. The 3861 is Omega’s first in-house manual-winding chronograph to earn METAS Master Chronometer certification, meaning it withstands magnetic fields up to 15,000 gauss and meets strict accuracy standards. It retains the manual-winding character of its predecessors but adds a Co-Axial escapement and 50-hour power reserve. This is the movement in every current Speedmaster Moonwatch Professional, reviewed in detail in our Speedmaster Moonwatch review.
The Modern Speedmaster (2021-2026)
When Omega updated the Moonwatch Professional in 2021, it made the most comprehensive changes to the watch since the original Moon landing. The case was subtly redesigned — the same 42mm diameter, but with a step dial, updated bracelet with polished pushers, and the option of hesalite crystal (the traditional plastic) or sapphire. The Calibre 3861 brought Master Chronometer certification without sacrificing the manual-winding DNA that defines the Speedmaster experience.
In 2024, Omega expanded the collection with a white-dial Moonwatch Professional featuring a recessed minute track. The start of 2026 saw the introduction of new “Inverted Panda” options, pairing black lacquer with white subdials for a high-contrast aesthetic that has been a hit with collectors.
Beyond the Moonwatch, the Speedmaster family now includes the Speedmaster ’57 (a retro-styled automatic), the Speedmaster Racing (motorsport-focused), and the Speedmaster Super Racing (with the advanced Spirate system for extreme accuracy). Each variant expands the collection’s reach while the Moonwatch Professional remains the anchor.
The current Moonwatch Professional retails at approximately $7,200 on bracelet in 2026 — roughly the same inflation-adjusted price as the original CK2915 cost in 1957, making it one of the most historically significant watches you can buy at any price.

Buying a Speedmaster in 2026
The Speedmaster Moonwatch Professional in steel starts at approximately $6,300 on a NATO strap and $7,200 on the steel bracelet. The hesalite (acrylic crystal) version is the purist’s choice — it is historically accurate and slightly cheaper — while the sapphire version offers a display caseback and scratch resistance. Both use the same Calibre 3861.
On the secondary market, pre-owned Speedmaster Professionals trade from $4,500 to $5,500 depending on condition and documentation. Vintage references with the Calibre 861 or 1861 offer the classic Moonwatch experience at a lower entry point. For collectors, the Silver Snoopy Award editions and the Calibre 321 re-editions are the ones to watch — they have consistently appreciated in value.
If the Moonwatch is over budget, consider the Zenith El Primero or one of our best chronographs under $3,000 as alternatives.

Frequently Asked Questions
Was the Omega Speedmaster the first watch in space?
No. The first watch in space was a Soviet Sturmanskie worn by Yuri Gagarin in 1961. The Speedmaster was the first Omega in space (Wally Schirra, 1962) and the first watch worn on the Moon (Buzz Aldrin, 1969). It is also the only watch NASA has ever officially flight-qualified for manned space missions.
Why is the Speedmaster called the Moonwatch?
Omega began using the “Moonwatch” name after the Apollo 11 Moon landing in 1969, when Buzz Aldrin wore a Speedmaster reference 105.012 on the lunar surface. It has been used as an official product name for the Speedmaster Professional ever since, and the watch remains the only one to have been worn during a Moon landing.
How much does an Omega Speedmaster cost in 2026?
The current Moonwatch Professional in stainless steel retails from approximately $6,300 (NATO strap) to $7,200 (steel bracelet). Pre-owned examples start around $4,500. The Speedmaster ’57 automatic costs around $8,000-9,000, and precious-metal editions begin above $28,000. The reissued Calibre 321 editions retail above $14,000.
Is the Speedmaster a good investment?
Standard production Speedmasters depreciate moderately — expect to lose 15-25% from retail on the secondary market. However, limited editions like the Silver Snoopy Award (both 2015 and 2020 versions) have appreciated significantly, with the 2020 Snoopy now trading above $20,000 against a $9,600 retail price. The Calibre 321 re-editions have also held or increased in value.
Should I buy the hesalite or sapphire Speedmaster?
The hesalite (acrylic crystal) version is the historically accurate choice — it matches what the astronauts wore and costs less. It scratches more easily but scratches can be polished out with Polywatch. The sapphire version is more practical for daily wear, offers a display caseback showing the Calibre 3861, and resists scratches. Most collectors choose hesalite for the heritage; most daily wearers choose sapphire for durability.
What movement does the current Speedmaster use?
The current Speedmaster Moonwatch Professional uses the Calibre 3861, a manual-winding chronograph with Co-Axial escapement, METAS Master Chronometer certification, 50-hour power reserve, and magnetic resistance to 15,000 gauss. It is the direct descendant of the original Calibre 321 that went to the Moon.
How does the Speedmaster compare to the Rolex Daytona?
Both are iconic chronographs, but they serve different markets. The Daytona ($15,100 retail, with waitlists of several years) is primarily a luxury status symbol with strong investment potential. The Speedmaster ($7,200 retail, generally available) offers genuine space-programme heritage, a manual-winding experience, and a lower entry price.
