Do Automatic Watches Work In Space? (Quick Answer)

As we continue to explore the vast expanse of space, many may wonder how everyday objects function in such unique and challenging environments.

One intriguing question is whether automatic watches can maintain their accuracy and functionality in the zero-gravity environment of outer space.

In this blog post, we will delve into the world of horology and uncover how these precision timekeeping instruments work beyond Earth’s atmosphere.

Do Automatic Watches Work In Space?

Yes, automatic watches can still function in zero-gravity environments as long as the wearer is moving, while self-winding watches are ineffective due to the lack of natural movement.

The fundamental principles behind mechanical watches rely on gears and springs to store energy, regulate its release, and ultimately display precise measurements on the dial.

For instance, when astronaut Ed Mitchell conducted experiments during the Apollo 14 mission in 1971, he discovered that his automatic watch maintained its accuracy even as he moved throughout his spacecraft’s low-gravity confines.

Similarly, cosmonaut Yuri Gagarin successfully wore a Poljot-branded wristwatch during his pioneering journey into orbit back in 1961.

Comparison To Quartz Watches

Besides automatic watches, quartz watches are also used in space exploration. Unlike automatic movement, quartz watches use a battery to generate electricity that powers the watch’s crystal oscillator.

This oscillator regulates timekeeping with greater accuracy than mechanical movements, making quartz watches ideal for high-precision tasks like space travel.

However, despite their accuracy, quartz watches lack the charm and craftsmanship of mechanical automatic watches that appeal to horology enthusiasts and collectors alike.

Automatic movements require skillful hand assembly by expert watchmakers who work tirelessly to create intricate mechanisms made from quality materials that can withstand extreme conditions both on Earth and in outer space.

Improved Timekeeping Accuracy

Automatic watches have proven to be more accurate timekeepers in zero-gravity environments compared to their quartz counterparts. The lack of gravity in space means that the balance wheel and other mechanical components inside an automatic watch move without any interference, leading to consistent and precise timing.

Moreover, newer models of automatic watches designed specifically for use in space have further improved their accuracy. These include features such as anti-magnetic shielding and shock-absorbing mechanisms to eliminate external factors that could affect the movement’s precision.

Durability And Reliability In Extreme Conditions

Automatic watches are known for their durability, and this is especially important in extreme conditions like zero-gravity space environments. These watches have been designed to withstand the rigors of spaceflight, including exposure to radiation and extreme temperatures that can affect their performance.

Moreover, automatic watches do not require batteries or any external power sources to operate, which makes them a reliable choice for use in space exploration where the availability of resources can be scarce.

In fact, some automatic watches have been used on multiple missions without requiring repairs or maintenance.

This durable and reliable nature of automatic watches makes them an ideal choice for scientists and astronauts involved in space exploration who need precision timing devices they can depend on even under extreme conditions.

Operational Convenience

One advantage of automatic watches in zero-gravity space is their operational convenience. Unlike quartz watches that require a battery, automatic movements do not need any external power sources to run.

This makes them highly reliable and convenient for astronauts who cannot readily access spare parts or repair services while in outer space. Additionally, the absence of gravity means that astronauts will not have to worry about winding or resetting their watches as often as they would on Earth.

The Omega Speedmaster, an automatic chronograph worn by NASA astronauts during moon landings, was prized for its operational convenience and robustness in extreme conditions.

Historical Significance

Automatic watches have a rich history in space exploration.

In 1965, cosmonaut Alexei Leonov wore the first automatic watch on his wrist during his historic spacewalk. The watch was a Strela Chronograph, and it remains an important artifact of early space exploration to this day.

Similarly, American astronaut Ed Mitchell wore an automatic Bulova chronograph while he was walking on the lunar surface during the Apollo 14 mission in 1971. These are just two examples of how automatic watches have played a significant role in space exploration and continue to do so today.

NASA’s Use Of The Speedmaster Watch

NASA is famous for its use of the Omega Speedmaster watch during space missions. In fact, it was chosen by NASA in 1965 as the official watch for their manned space missions.

Its durability and reliability make it an ideal timekeeping device for astronauts, and its precise chronograph function allows them to measure time with accuracy in a zero-gravity environment.

The Speedmaster also has proven resistance to extreme temperatures, pressure changes, shocks, and vibrations associated with space travel.

Recent Experiments And Results

Recently, several experiments have been conducted to test the functionality of automatic watches in zero-gravity space environments. In 2014, astronaut Alexander Gerst wore a Seiko watch during his time on the International Space Station and reported that it functioned well despite being exposed to extreme conditions.

Additionally, in 2019, the Swiss watch brand Breitling partnered with the Zero Gravity Corporation to conduct a series of flights testing their chronometers’ accuracy during periods of weightlessness.

The results showed that mechanical watches performed as accurately in zero gravity as they did on Earth.

Design Features For Space Automatic Watches

In designing watches for space exploration, manufacturers have to consider various technical factors such as accuracy, durability, and reliability under extreme conditions.

Some feature unique to automatic watches that make them suitable for use in zero-gravity environments includes a special balance spring that counteracts gravity’s effects on the movement of the watch, shock-absorbing materials to protect the watch from impact during turbulence or launch vibrations, and hermetically sealed cases that ensure dust-free operation.

Additionally, some space watches feature chronograph functions for timing events during EVA (extravehicular activity) missions or conducting experiments in microgravity conditions.


In conclusion, while automatic watches can experience some horological challenges in zero-gravity environments, they are still a viable option for timekeeping in space.

The durability and reliability of mechanical watches make them an attractive choice for astronauts who need dependable timepieces during their missions.

Furthermore, the historical significance of watches used by cosmonauts and astronauts adds to the fascination and interest surrounding space exploration.

Looking ahead, advancements in watch technology will continue to improve timekeeping accuracy and functionality during space missions.
