The Rolex GMT-Master II, a watch synonymous with travel and precision, boasts a GMT hand that allows the wearer to track a second time zone simultaneously with the local time. While the elegance and functionality of this iconic timepiece are undeniable, setting the GMT hand correctly can seem daunting to some. This comprehensive guide will walk you through the process of setting the GMT hand on a Rolex GMT-Master II (specifically referencing the 116710BLNR, but the principles apply to most models), covering various aspects from basic time and date setting to advanced troubleshooting. We'll also delve into frequently asked questions and address common concerns related to this specific function.
Understanding the Rolex GMT-Master II and its Functionality
Before we jump into the setting process, let's briefly understand the architecture of the Rolex GMT-Master II. The watch features three hands:
* Hour Hand: Indicates the local time.
* Minute Hand: Indicates the minutes in the local time.
* GMT Hand (24-hour hand): Indicates a second time zone, typically using a 24-hour format. This hand completes a full rotation in 24 hours, with the first 12 hours often represented in lighter color and the remaining 12 hours in darker color (or vice-versa, depending on the model).
The crown, the winding mechanism on the side of the watch, is crucial for setting all three hands. Different positions of the crown activate different setting functions. The specific actions and crown positions may vary slightly depending on the exact Rolex GMT-Master II model, but the general principles remain consistent.
Rolex Setting Date and Time: A Foundation for GMT Setting
Before tackling the GMT hand, you need to master setting the main time. This is fundamental to understanding the overall adjustment process. Here's how to set the date and time on your Rolex GMT-Master II:
1. Unscrew the Crown: Gently unscrew the crown counter-clockwise until it is free. Do this carefully to avoid damaging the crown or the gaskets that ensure water resistance.
2. Pull the Crown to the First Click (Position 1): Pulling the crown out to the first click allows you to adjust the date. Rotate the crown clockwise to advance the date. Note that some Rolex models only allow date adjustment in one direction.
3. Pull the Crown to the Second Click (Position 2): Pulling the crown out to the second click allows you to set the time. Rotate the crown clockwise or counter-clockwise to set the hour and minute hands to the correct local time.
4. Push the Crown Back In: Once the time and date are correctly set, gently push the crown back in to its original position. Ensure it is fully screwed down to maintain water resistance.
Setting a Rolex Watch GMT: Focusing on the GMT Hand
Now, let's move on to setting the GMT hand. This is where the magic of the GMT-Master II truly shines. The process typically involves these steps:
1. Unscrew and Pull the Crown: As before, unscrew the crown and pull it out to the second click (Position 2). This position allows you to adjust the hour, minute, and GMT hands simultaneously.
