How To Wind Omega Speedmaster Professional

by Barbara Wilson

The Omega Speedmaster Professional, renowned for its association with NASA’s space missions and its distinctive design, is a chronograph watch that demands precise care. Proper winding is essential to ensure the watch operates accurately and maintains its longevity. This detailed guide will walk you through the step-by-step process of winding the Omega Speedmaster Professional, including insights into its mechanisms, care, and best practices.


Understanding the Omega Speedmaster Professional

Historical Significance and Design

The Omega Speedmaster Professional, also known as the “Moonwatch,” gained fame for its role in space exploration. It was the first watch worn on the moon during the Apollo 11 mission. The design is robust, featuring a stainless steel case, a manual-winding chronograph movement, and a tachymetric scale bezel. The manual-winding mechanism is central to its operation, differentiating it from automatic or quartz watches.


Movement and Mechanism

The Speedmaster Professional is powered by the Omega Caliber 1861 movement, an evolution of the Caliber 861. It is a manual-winding chronograph movement, meaning it requires manual winding to function. The movement features a column wheel chronograph mechanism and a manual winding escapement that ensures precise timekeeping.


The Importance of Proper Winding

Ensuring Accurate Timekeeping

Manual winding ensures the movement remains powered, allowing the watch to keep accurate time. Regular winding avoids power depletion and maintains the watch’s precision.


Maintaining the Movement

Winding the watch also helps to keep the lubricants within the movement evenly distributed. This distribution reduces friction and wear, contributing to the overall longevity of the watch.

Step-by-Step Guide to Winding the Omega Speedmaster Professional

1. Prepare the Watch

Before you begin winding, ensure the watch is clean and free from any dirt or debris that might affect its operation. It’s also best to do this in a clean, well-lit area to avoid any potential damage.

2. Locate the Crown

The crown is the small, round knob on the side of the watch case. On the Speedmaster Professional, the crown is located at 3 o’clock. This is where you’ll engage in the winding process.

3. Pull Out the Crown to the First Position

Gently pull the crown out to the first position. This is the winding position. Do not pull the crown out to the second position (time-setting position) or the third position (chronograph function) during winding.

4. Begin Winding

Turn the crown clockwise slowly and steadily. You should feel resistance as the mainspring within the movement tightens. Be cautious not to overwind the watch; turn the crown until you feel significant resistance. Overwinding can damage the movement.

5. Count the Turns

Typically, the Speedmaster Professional requires about 40 turns of the crown to fully wind. This varies slightly based on the watch’s state of power reserve. It’s important to wind the watch until you encounter a firm resistance.

6. Check the Power Reserve

Once you’ve finished winding, check the watch’s power reserve. If the watch is running smoothly and keeping accurate time, you’ve successfully completed the winding process. If the watch stops or is inconsistent, it may need servicing.

7. Push the Crown Back

After winding, push the crown back into its original position. This secures the winding mechanism and ensures the watch remains water-resistant and protected.

Best Practices for Winding Your Speedmaster Professional

Regular Winding

Even if you’re not wearing the watch daily, wind it regularly to keep the lubricants evenly distributed and avoid any issues with the movement.

Avoid Overwinding

Do not force the crown beyond its resistance. Overwinding can cause damage to the internal components. If you feel significant resistance, stop winding.

Maintain Consistency

Develop a routine for winding your watch, whether daily or weekly, depending on your wearing habits. Consistent winding helps maintain the watch’s accuracy and function.

Service Your Watch Regularly

Even with proper winding, the Speedmaster Professional requires regular servicing every 5 to 7 years. This maintenance ensures that all components are in good working order and lubricants are properly applied.

Common Issues and Troubleshooting

Watch Not Winding

If the watch is not winding properly, check if the crown is correctly engaged in the winding position. If the issue persists, it might be due to internal movement problems or a need for servicing.

Resistance During Winding

If you experience unusual resistance during winding, stop immediately and consult a professional watchmaker. This could indicate an issue with the mainspring or other internal components.

Power Reserve Problems

If the watch stops running despite proper winding, it might be an indication of a power reserve issue or a malfunction within the movement. Have the watch checked by a professional.


Proper winding of the Omega Speedmaster Professional is crucial for maintaining its precision and longevity. By following these detailed steps and adhering to best practices, you ensure that your watch remains in excellent condition and continues to perform as intended. Remember, regular maintenance and careful handling are key to preserving the heritage and functionality of this iconic timepiece.
