The Omega Seamaster is a revered collection in the world of luxury watches. Its blend of precision engineering, aesthetic appeal, and functional versatility has made it a favorite among watch enthusiasts and professionals alike. One of the standout features of certain models within the Seamaster line is the GMT function, which allows the wearer to track multiple time zones simultaneously. This guide will provide a step-by-step walkthrough on how to set the GMT hand on an Omega Seamaster, along with additional insights into the GMT function and its practical applications.
Understanding the GMT Function
Before diving into the step-by-step instructions on setting the GMT hand, it’s essential to understand what the GMT function is and why it is valuable.
What is GMT?
GMT stands for Greenwich Mean Time, which is the mean solar time at the Royal Observatory in Greenwich, London. It has been used as the global time standard since the late 19th century. The GMT function on a watch enables the wearer to track two different time zones simultaneously. This feature is especially useful for travelers, business professionals, and anyone who frequently communicates across different time zones.
The GMT Hand on Omega Seamaster
The GMT hand is an additional hand on the watch dial that circles the dial once every 24 hours, unlike the hour hand, which completes a full circle in 12 hours. The GMT hand points to the 24-hour markers, usually located on the bezel or an inner track of the dial, allowing the wearer to track a second time zone.
How to Set the GMT Hand on an Omega Seamaster
Setting the GMT hand on your Omega Seamaster is a straightforward process, but it requires attention to detail to ensure accuracy. The following steps will guide you through the process.
Step 1: Unscrew the Crown
Locate the Crown: The crown is the small knob usually positioned on the right side of the watch case.
Unscrew the Crown: Gently unscrew the crown by rotating it counterclockwise. Continue turning until the crown pops out slightly. This action unlocks the crown and allows you to manipulate the watch’s functions.
Step 2: Pull the Crown to the Second Position
Pull the Crown: Once the crown is unscrewed, pull it out gently to the second position. On most Omega Seamaster models, the crown has three positions:
First Position: Winding the movement.
Second Position: Setting the date and GMT hand.
Third Position: Setting the time (hour and minute hands).
Confirm the Second Position: Ensure that the crown is in the second position, which allows you to adjust the GMT hand and date. You should feel a slight click as the crown reaches this position.
Step 3: Rotate the Crown to Set the GMT Hand
Identify the Direction: Depending on the model, you may need to rotate the crown either clockwise or counterclockwise to adjust the GMT hand. Refer to your specific Omega Seamaster manual if unsure.
Set the Desired Time Zone: Rotate the crown until the GMT hand points to the correct hour on the 24-hour scale, representing your second time zone. The 24-hour markers can be on the bezel or an inner ring on the dial, depending on your specific model.
Fine-Tune: Make small adjustments to ensure that the GMT hand is accurately aligned with the correct hour marker.
Step 4: Push the Crown Back to the First Position
Push the Crown: Once the GMT hand is set, gently push the crown back to the first position. This locks in the setting for the GMT hand and date adjustment.
Avoid Over-Pushing: Be careful not to push the crown too forcefully, as this might skip the first position and inadvertently reset the time.
Step 5: Set the Main Time (Hour and Minute Hands)
Pull the Crown to the Third Position: If you need to adjust the main time, pull the crown out to the third position. This allows you to set the hour and minute hands.
Rotate the Crown: Rotate the crown until the main time is correctly set to your local time.
Synchronize with GMT: If the main time and GMT are synchronized (e.g., you’re tracking two time zones that are closely related), ensure that the hour hand corresponds to the 24-hour scale of the GMT hand.
Step 6: Push the Crown Back and Screw it Down
Push the Crown Back: Once all settings are complete, push the crown back to its neutral position against the watch case.
Screw the Crown Down: Rotate the crown clockwise to screw it back into place. This ensures the watch remains water-resistant and secure.
Step 7: Double-Check the Settings
Inspect the GMT Hand: Ensure that the GMT hand is correctly aligned with the intended time zone.
Check the Main Time: Verify that the hour and minute hands are accurately set to your local time.
Confirm Date Accuracy: If you adjusted the date during the process, ensure it is correctly set.
Practical Applications of the GMT Function
The GMT function on your Omega Seamaster is more than just a technical feature; it offers practical benefits for various situations. Here are some examples of how to use the GMT hand effectively.
Tracking a Second Time Zone
The primary purpose of the GMT hand is to track a second time zone. This is particularly useful for frequent travelers, business professionals, and individuals who need to stay in touch with family or colleagues in different parts of the world.
Business Professionals: If you conduct business with clients or colleagues in a different time zone, you can set the GMT hand to their local time. This helps avoid confusion when scheduling meetings or making calls.
Travelers: When traveling to a different time zone, you can set the GMT hand to your home time. This allows you to keep track of local time while staying connected to the time at home.
Pilots and Aircrew: The GMT function is especially valuable for pilots and aircrew who cross multiple time zones. Setting the GMT hand to Coordinated Universal Time (UTC) helps maintain a consistent reference time during flights.
Using the GMT Hand as a Day/Night Indicator
The 24-hour nature of the GMT hand can also serve as a day/night indicator. This is particularly useful when you want to know whether it’s day or night in the second time zone you are tracking.
Adjusting for Time Differences: By observing the position of the GMT hand on the 24-hour scale, you can easily determine whether the second time zone is in daylight or nighttime, helping you decide the best time to make calls or send emails.
Scheduling Across Time Zones: If you manage schedules that span multiple time zones, the GMT hand can help you avoid scheduling conflicts by showing you the current time in both zones.
Enhancing Time Management
The GMT function can be a valuable tool for enhancing time management and productivity, especially for individuals who need to coordinate with teams or events across different time zones.
Dual Time Monitoring: For those who work with teams in different regions, the GMT hand allows for dual time monitoring, helping you manage deadlines and meetings more efficiently.
Balancing Work and Personal Life: If you frequently travel for work, the GMT function can help you maintain a balance between work commitments in one time zone and personal life in another.
Collectors and Enthusiasts
For collectors and watch enthusiasts, the GMT function represents both a practical and aesthetically pleasing feature. The presence of an additional hand and 24-hour markers adds complexity and visual interest to the watch dial.
Appreciating Horology: The GMT function is a testament to the craftsmanship and engineering that goes into luxury watches like the Omega Seamaster. Understanding and using this function enhances your appreciation of the watch’s design and functionality.
Display and Collection: Collectors often value GMT watches for their versatility and historical significance. Displaying a GMT watch as part of a collection showcases a deeper understanding of horological complications.

Common Questions About the Omega Seamaster GMT Function
Can I Use the GMT Hand to Track a Third Time Zone?
Yes, you can use the GMT hand in conjunction with the rotating bezel (if your model has one) to track a third time zone. By rotating the bezel to offset the 24-hour scale, you can temporarily adjust the GMT hand to reflect another time zone. However, this requires manual calculation and is less straightforward than tracking two time zones.
What Should I Do If the GMT Hand Doesn’t Move?
If you notice that the GMT hand is not moving or is not aligned correctly, it may be due to a mechanical issue within the movement. In such cases, it’s best to have the watch inspected by an authorized Omega service center. Avoid attempting to fix the issue yourself, as this could void the warranty or cause further damage.
How Accurate is the GMT Function on the Omega Seamaster?
The accuracy of the GMT function on the Omega Seamaster is generally very high, thanks to the precision engineering and quality control standards that Omega upholds. However, like all mechanical watches, slight variations in timekeeping can occur. Regular servicing and proper care will help maintain accuracy.
Can I Set the GMT Hand Independently of the Main Time?
On most Omega Seamaster models, the GMT hand is set independently of the main time (hour and minute hands). This allows you to track a different time zone without affecting the local time display. However, the exact method of setting may vary depending on the movement used in your specific model.
Is the GMT Function Useful for Daylight Saving Time?
Yes, the GMT function can be particularly useful during Daylight Saving Time (DST). When a region switches to DST, you can quickly adjust the main time while keeping the GMT hand set to the standard time of the second time zone. This helps you stay on track with international time differences.
Conclusion
The GMT function on the Omega Seamaster is a versatile and valuable feature, offering a range of practical applications for both daily use and travel. Whether you’re a frequent traveler, a business professional, or a watch enthusiast, mastering the GMT function enhances the utility and enjoyment of your Omega Seamaster. By following the steps outlined in this guide, you can confidently set the GMT hand and make the most of this remarkable horological complication.
