The Rolex GMT-Master II is a legendary watch, renowned for its ability to display multiple time zones simultaneously. This functionality, achieved through a clever combination of hands and a rotating bezel, makes it a favorite among frequent travelers and aviation enthusiasts. However, understanding how to interpret the information presented on the dial can be initially confusing. This article will provide a comprehensive guide to reading the GMT-Master II, exploring its various versions and addressing common user questions.
Understanding the Hands and Bezel:
The GMT-Master II typically features three hands working in concert:
* Hour Hand: This shorter hand indicates the local time in the currently selected time zone.
* Minute Hand: This longer hand, identical in function to the minute hand on most watches, indicates the minutes within the hour shown by the hour hand.
* 24-Hour Hand: This hand, often colored differently (red is common), completes a full rotation in 24 hours, indicating a second time zone. This hand is crucial for distinguishing AM from PM in the second time zone.
The watch also features a 24-hour bidirectional rotating bezel. This bezel is graduated in 24-hour increments, allowing the user to set a reference time zone. The combination of the 24-hour hand and the bezel is the key to displaying multiple time zones.
Setting and Reading the Time Zones:
1. Setting the Local Time: Set the hour and minute hands to the correct local time using the crown.
2. Setting the Second Time Zone (using the 24-hour hand): This is where the bezel comes into play. First, identify your reference time zone (e.g., your home time zone). Rotate the bezel until the zero mark (or 24) aligns with the hour hand. Now, set the 24-hour hand to the time in your reference time zone. For example, if it's 10 AM in your reference time zone, set the 24-hour hand to the 10 on the dial.
3. Reading the Time Zones:
* Local Time: Read the hour and minute hands to determine the local time.
* Reference Time Zone: Read the 24-hour hand against the 24-hour bezel. The number the 24-hour hand points to on the bezel represents the hour in your reference time zone. Remember, the numbers 1-12 represent AM, and 13-24 represent PM.
* Third Time Zone (Implied): While not directly displayed, you can calculate a third time zone by considering the difference between your local time and your reference time.
Examples:
Let's say your local time is 2 PM (shown by the hour and minute hands), and your reference time zone (set on the bezel) is 8 AM. The 24-hour hand would point to the '8' on the bezel. To calculate a third time zone, you would need to know the time difference between your local and reference time zones.
