In the following sections, we’ll explore the core features of a GMT watch and guide you through the essential steps to set and use it effectively. Whether you’re new to GMT watches or looking to refine your skills, this guide will help you unlock the full potential of this remarkable horological innovation.

Setting the Local and GMT Time

To effectively use a GMT watch, it is essential to understand how to set both the local time and the GMT (or second time zone) accurately. Most GMT watches feature an independent hour hand for local time and a 24-hour hand for GMT time, often paired with a rotating bezel or fixed 24-hour scale.

Begin by unscrewing or pulling out the crown to the appropriate setting position, which varies by model. Generally, the first position allows adjustment of the GMT hand independently of the local hour hand. Set the GMT hand to the desired reference time zone, often GMT (Greenwich Mean Time) or UTC (Coordinated Universal Time), by rotating the crown. This hand should follow a 24-hour format, meaning it completes one full rotation every 24 hours rather than every 12.

Next, pull the crown to the second position to adjust the local hour hand. This hand should be set to your current local time. Notably, many GMT watches allow the local hour hand to be adjusted in one-hour increments without stopping the seconds or affecting the GMT hand. This feature is particularly useful for travelers crossing time zones, as it enables quick local time adjustments without losing track of the reference time.

Reading Multiple Time Zones

A GMT watch allows you to track two or more time zones simultaneously. The key elements include:

  • Local hour hand: Displays your current local time.
  • GMT hand: Displays the reference time zone in 24-hour format.
  • Rotating bezel (if available): Can be used to calculate a third time zone.

To read the second time zone, simply look at the GMT hand against the 24-hour scale on the watch dial or bezel. For example, if the GMT hand points to 22 on the bezel, the reference time is 22:00 hours (10 PM).

If you need to track a third time zone, rotate the bezel to offset the GMT hand’s position by the desired number of hours. This method is especially helpful for pilots or frequent travelers who need to monitor multiple time zones.

Using the Rotating Bezel for Additional Time Zones

Not all GMT watches have a rotating bezel, but when present, it adds significant functionality. The bezel typically has a 24-hour scale and can be turned to align with the GMT hand for quick calculation of a third time zone.

Here’s how to use it:

  • Determine the time difference between the GMT hand’s current reference time and the third time zone.
  • Rotate the bezel clockwise or counterclockwise to offset the 24-hour scale by that time difference.
  • Read the third time zone by noting where the GMT hand points on the rotated bezel.

This method does not require adjusting the watch hands and provides an instant reference to an additional time zone.

Common Features and Complications in GMT Watches

GMT watches come with various features that enhance their functionality. Understanding these will help you make the most of your timepiece:

Understanding the Components of a GMT Watch

A GMT (Greenwich Mean Time) watch features specialized components that distinguish it from a standard timepiece. Familiarity with these parts is essential for effective use.

  • Hour Hand: Indicates the local hour, typically adjustable independently of the minute and second hands.
  • Minute Hand: Displays the minutes, synchronized with the hour and second hands.
  • Second Hand: Tracks seconds in real time.
  • 24-Hour Hand (GMT Hand): A distinct hand, often styled differently (e.g., arrow tip), that makes one full rotation every 24 hours.
  • Rotatable 24-Hour Bezel: Marked with 24-hour indices, this bezel allows for tracking a second or third time zone.
  • Crown: Used to set time, date, and adjust the GMT hand.
Component Function Typical Adjustment
Hour Hand Displays local time hours Independently adjustable for local time changes
Minute Hand Displays minutes Set with main time
Second Hand Tracks seconds Set with main time
24-Hour GMT Hand Indicates a second time zone in 24-hour format Set independently to GMT or desired zone
Rotatable Bezel Allows tracking of a third time zone Turn bezel to align 24-hour markers

Setting the Local Time and GMT Hand

Setting a GMT watch correctly involves configuring both the local time and the GMT hand to track two different time zones.

  1. Pull the Crown to the First Position: This typically allows adjustment of the hour hand independently, without stopping the watch.
  2. Set the Local Time: Rotate the crown to move the hour hand to the current local hour. The minute and second hands remain unaffected.
  3. Pull the Crown to the Second Position: This position allows adjustment of the minute and second hands.
  4. Set the Minutes and Seconds: Align these with the correct local time.
  5. Set the GMT Hand: Usually, the GMT hand can be set by pulling the crown to a specific position or using a dedicated pusher, depending on the model. Adjust the GMT hand to the reference time zone, often GMT or your home time.
  6. Push the Crown Back In: Secure the settings and resume normal watch operation.

This dual adjustment allows the wearer to see both local time and a second time zone simultaneously.

Using the GMT Bezel to Track Additional Time Zones

The GMT bezel enhances the watch’s capability by enabling tracking of a third time zone. The bezel is graduated in 24 hours and rotates bi-directionally.

  • Align the Bezel: Rotate the bezel so that the GMT hand points to the correct hour on the bezel corresponding to the third time zone.
  • Reading the Third Time Zone: The bezel’s 24-hour scale, combined with the GMT hand, indicates the hour in the third zone.
  • Example: If the GMT hand shows 14:00 (2 PM) and you rotate the bezel 3 hours forward, the bezel will now show 17:00 (5 PM), representing a third time zone 3 hours ahead of GMT.

Using the bezel in this way requires understanding the relationship between the GMT hand’s position and the bezel’s scale.

Practical Tips for Effective Use of a GMT Watch

  • Understand 24-Hour Format: The GMT hand uses a 24-hour scale to avoid confusion between AM and PM.
  • Set the GMT Hand to a Fixed Reference: Many travelers set the GMT hand to their home time zone, allowing quick reference while abroad.
  • Adjust Local Time Independently: When crossing time zones, adjust only the local hour hand to reflect the new local time while keeping the GMT hand constant.
  • Use the Bezel for Temporary Zones: Rotate the bezel to quickly calculate time in an additional zone, especially useful for meetings or calls.
  • Synchronize Before Travel: Always set the GMT hand and local time accurately before departure to avoid confusion.
  • Be Cautious with Date Changes: Some GMT watches change the date according to the local hour hand, so setting the local time past midnight may alter the date.

Reading the Time on a GMT Watch

To read time effectively on a GMT watch:

  • Local Time: Read as usual using the hour, minute, and second hands.
  • Second Time Zone: Read the GMT hand against the fixed 24-hour markers on the dial or bezel (if bezel is set to zero).
  • Third Time Zone: If using the bezel, add or subtract the bezel’s offset from the GMT hand’s reading to find the third zone.
