The Rolex GMT-Master II, with its iconic bidirectional rotating bezel and independently adjustable GMT hand, is a coveted timepiece for frequent travelers and anyone who needs to track multiple time zones simultaneously. However, understanding how to correctly manipulate this sophisticated mechanism is crucial to avoid damaging the watch. This comprehensive guide will walk you through the process of setting the GMT hand on a Rolex GMT-Master II (using the 116710BLNR as a reference, but applicable to most models), covering various aspects from basic time and date setting to troubleshooting common issues.
I. Understanding the Rolex GMT-Master II Mechanism
Before diving into the practical steps, let's clarify the functionality of the GMT-Master II. Unlike a standard watch that only displays local time, the GMT-Master II features two independent timekeeping functions:
* Local Time: This is displayed by the hour, minute, and second hands. It's the time in your current location.
* GMT Time (or Second Time Zone): This is indicated by the independently adjustable GMT hand, usually marked with a different color (often red). This hand typically tracks Coordinated Universal Time (UTC), but can be set to any other time zone.
The bidirectional rotating bezel, with its 24-hour graduated markings, acts as a secondary time zone indicator. It allows you to easily read a third time zone by aligning the bezel's markings with the GMT hand.
II. Setting a Rolex Watch GMT: A Step-by-Step Guide
The crown on the Rolex GMT-Master II is the key to adjusting all timekeeping functions. It operates in three positions:
* Position 0 (Screwed Down): This is the normal, water-resistant position. The crown is screwed tightly into the case.
* Position 1 (First Unscrew): Unscrew the crown gently. In this position, you can set the date.
* Position 2 (Fully Unscrewed): Continue unscrewing the crown fully. In this position, you can set the time (hour, minute, and second hands) and the GMT hand.
Setting the Date and Time (Rolex Setting Date and Time):
1. Unscrew the Crown: Gently unscrew the crown to Position 1.
2. Set the Date: Turn the crown clockwise to advance the date. You can only adjust the date forward, not backward. It's best to do this during the afternoon to avoid potential complications.
3. Unscrew the Crown Further: Turn the crown to Position 2.
4. Set the Time: Carefully adjust the hour, minute, and second hands using the crown. Turn the crown clockwise to advance the time and counterclockwise to rewind. Ensure the seconds hand aligns precisely with the markers.
5. Set the GMT Hand: Once the local time is set, use the crown to adjust the GMT hand. This hand moves independently of the hour, minute, and second hands. Rotate the crown to set the GMT hand to the desired time zone.
Setting the Rolex GMT Master 2 Time Zone (Rolex GMT Master 2 Time Zone):
This is essentially setting the GMT hand. Remember that adjusting the GMT hand does *not* affect the local time displayed by the hour, minute, and second hands. The bezel helps you visualize the relationship between the GMT time and other time zones.
