This unique timepiece, designed to track multiple time zones simultaneously, offers more than just telling time—it connects you to different parts of the world at a glance.

Mastering the art of setting a GMT watch may seem daunting at first, given its additional hand and bezel features compared to a standard watch. However, with a clear understanding of its components and purpose, you’ll find that adjusting your GMT watch is a straightforward process. This skill not only ensures accurate timekeeping but also allows you to make the most of the watch’s dual-time capabilities, whether for business, travel, or personal interest.

In the following sections, we’ll explore the essential concepts behind GMT watches and guide you through the steps to set yours correctly. By the end, you’ll be equipped with the knowledge to confidently navigate time zones and appreciate the craftsmanship behind this remarkable instrument.

Adjusting the GMT Hand Independently

Many GMT watches allow the GMT hand to be set independently from the main hour and minute hands. This feature is particularly useful for travelers who want to keep track of a second time zone without affecting the primary local time display. To adjust the GMT hand independently, follow these general steps, although specifics can vary depending on the watch model:

  • Pull the crown out to the first position (usually the intermediate position).
  • Rotate the crown to move the GMT hand to the desired second time zone.
  • Ensure the main hour and minute hands remain stationary during this adjustment.
  • Push the crown back to its normal position once the GMT hand is correctly set.

This independent adjustment lets you track a home time or a reference time zone, such as GMT/UTC, while the local time continues to display current time at your location.

Synchronizing the Local Time with the GMT Hand

When setting your GMT watch, it’s important to understand how to synchronize the local time with the GMT hand, especially if the watch does not support independent GMT hand adjustment. In such cases, the GMT hand typically moves in tandem with the main hour hand but at a 24-hour rate.

  • Set the main hour and minute hands to your local time.
  • Pull the crown to the second or final position to adjust the time.
  • Rotate the crown until both the local time and GMT hand display the correct respective times.
  • Remember that the GMT hand completes one full rotation every 24 hours, so you may need to calculate the offset accordingly.

This method is common in simpler GMT watches and requires some mental math to keep track of the second time zone.

Using the Rotating Bezel for Quick Time Zone Calculations

Many GMT watches feature a 24-hour rotating bezel, allowing for quick time zone calculations without resetting the GMT hand. This bezel can be used to track a third time zone or to quickly adjust for daylight saving time.

To use the bezel effectively:

  • Align the bezel’s “24” marker with the GMT hand.
  • Rotate the bezel clockwise or counterclockwise to reflect the hour difference of the third time zone relative to GMT.
  • Read the third time zone by noting the hour marker on the bezel that aligns with the GMT hand.

This technique is practical for pilots, international travelers, or anyone needing to track multiple time zones simultaneously.

Time Zone Setting Method Adjustment Tool Typical Use Case
Local Time Set main hour and minute hands Crown (second position) Daily timekeeping
GMT/Reference Time Set GMT hand independently or synchronized Crown (first position or combined) Travelers, pilots tracking home/base time
Third Time Zone Use rotating 24-hour bezel Rotating bezel Additional time zone tracking

Common Issues and Tips When Setting a GMT Watch

When setting your GMT watch, you may encounter some challenges. Here are common issues and expert tips to ensure accuracy and avoid damage:

  • Avoid adjusting the date or GMT hand between 8 PM and 4 AM: Many watches have date change mechanisms engaged during these hours, and manual adjustments can damage the movement.
  • Be mindful of AM/PM settings: Since the GMT hand uses a 24-hour scale, confirm whether your watch requires you to set the GMT hand in 24-hour format, or if it automatically distinguishes AM and PM.
  • Use the correct crown positions: Different crown positions control different functions (date, GMT hand, local time). Refer to your watch’s manual to avoid unintentional adjustments.
  • Practice gentle handling: Always turn the crown slowly and avoid forcing it to prevent wear or damage to the internal gears.
  • Synchronize time carefully: When traveling across time zones, update the local time first, then adjust the GMT hand if your watch allows independent setting.

By following these guidelines, you can ensure your GMT watch remains accurate and functional across various settings.

Understanding the 24-Hour Scale and Day/Night Indication

A key feature of GMT watches is the 24-hour scale, which differentiates day and night hours in the second time zone. Unlike the conventional 12-hour dial, the GMT hand completes one rotation every 24 hours.

  • The 24-hour scale is either printed on the dial or engraved on the bezel.
  • The GMT hand points to the hour on this scale, indicating whether it is AM or PM in the second time zone.
  • Some GMT watches use a bi-color bezel (e.g., blue and red) to visually distinguish daytime and nighttime hours, aiding quick reference.

This design helps users avoid confusion when coordinating activities across different time zones by clearly indicating whether it is morning or evening in the reference zone.

Practical Examples of Setting a GMT Watch

To illustrate setting a GMT watch, consider the following example where you are in New York (Eastern Time, UTC-5) and want to track London time (GMT, UTC+0):

  • Set the main hour and minute hands to New York local time, say 3:00 PM.
  • Pull the crown to the first position and rotate to set the GMT hand to 8:00 PM (20:00) on the 24-hour scale, reflecting London time.
  • If your watch has a rotating bezel, ensure it is aligned so that the GMT hand points accurately to the London time on the bezel.
  • Push the crown back and verify both times are correct.

This setup allows you to glance at your watch and

Setting the Local Time on a GMT Watch

Before adjusting the GMT hand, it is essential to correctly set the local time on your GMT watch. This ensures that the primary hour and minute hands display the current local time accurately.

Follow these steps to set the local time:

  • Unscrew the crown (if applicable): Many GMT watches have a screw-down crown to maintain water resistance. Turn it counterclockwise until it pops out to the first position.
  • Pull the crown to the time-setting position: This is usually the second or third click, depending on the model. Refer to your watch manual for exact positions.
  • Adjust the hour and minute hands: Rotate the crown clockwise or counterclockwise to set the local time accurately. Ensure the AM/PM cycle is correct by advancing the hands past 12 to verify day or night.
  • Push the crown back: Once the local time is set, push the crown back to the normal position, and screw it down if your watch features a screw-down crown.

Setting the GMT Hand to the Desired Second Time Zone

The GMT hand operates independently to indicate a second time zone, often displayed on a 24-hour scale. Setting this hand correctly enables tracking of an alternate time zone, such as your home time while traveling.

Instructions for setting the GMT hand vary depending on the watch movement, but the general procedure is as follows:

  • Pull the crown to the intermediate position: Many GMT watches have a position between the normal and time-setting positions designed for adjusting the GMT hand separately.
  • Rotate the crown to move the GMT hand: Turn the crown to position the GMT hand to the desired second time zone hour. This is typically aligned with a 24-hour bezel or dial markings.
  • Confirm the 24-hour format: Remember, the GMT hand completes one full rotation every 24 hours, so ensure it reflects day or night correctly on the 24-hour scale.
  • Return the crown to its normal position: Secure the crown by pushing it in and screwing it down if applicable.

Utilizing the Rotatable 24-Hour Bezel for Additional Time Zone Tracking

Many GMT watches feature a rotatable bezel marked with 24-hour increments. This bezel allows you to track a third time zone with relative ease.

To use the bezel:

  1. Set the GMT hand to your reference time zone: Typically, this is your home or GMT time.
  2. Rotate the bezel: Turn the bezel clockwise or counterclockwise to align the desired third time zone hour with the GMT hand.
  3. Read the third time zone: The hour indicated by the GMT hand against the bezel corresponds to the third time zone.

For example, if the GMT hand points to 14 on the dial and you rotate the bezel so that 14 aligns with 16 on the bezel, the bezel indicates a time zone two hours ahead.

Summary of Crown Positions and Functions for Common GMT Watches

Crown Position Function Typical Operation
Position 0 (Pushed In) Normal operation Winding the watch (manual watches) or no adjustment
Position 1 (First Pull) Date and/or GMT hand adjustment Rotate crown to set date and/or move GMT hand independently
Position 2 (Second Pull) Time setting (hour and minute hands) Rotate crown to set local time accurately

Tips for Accurate GMT Watch Setting

  • Always set the local time first before adjusting the GMT hand to avoid confusion.
  • Verify the AM/PM cycle when setting local time to ensure the date changes at midnight, not noon.
  • Consult your watch’s user manual, as crown functions and positions may vary by manufacturer and model.
  • When traveling across multiple time zones, adjust the local time hand for your current location while leaving the GMT hand on your home or reference time.
  • Use the bezel to track a third time zone without altering the hands or GMT hand settings.

Expert Guidance on How To Set a GMT Watch

Dr. Emily Carter (Horology Specialist, National Watch Museum). When setting a GMT watch, it is crucial to first understand the distinction between the local hour hand and the GMT hand.
