The Rolex GMT-Master II is a legendary watch renowned for its ability to display multiple time zones simultaneously. While it can technically display *three* time zones (more on that later), its primary function is the clear and convenient indication of two distinct locations. This article will provide a comprehensive guide on how to set your Rolex GMT-Master II for two time zones, covering everything from basic time and date setting to understanding the watch's crown positions and intricacies of the GMT hand. We'll break down the process step-by-step, ensuring you master this iconic watch's functionality.
Understanding the GMT-Master II's Timekeeping Mechanism:
Before diving into the setting procedure, it's crucial to grasp the fundamental mechanism of the GMT-Master II. Unlike a standard watch with only an hour, minute, and second hand, the GMT-Master II incorporates a fourth hand – the 24-hour hand (often referred to as the GMT hand). This hand makes a complete revolution in 24 hours, providing a second time zone indication independent of the standard hour hand.
The standard hour, minute, and second hands display the *local time*, while the 24-hour hand indicates a *second time zone*. The bezel, with its 24-hour graduated markings, acts as a crucial reference point for reading the second time zone.
Rolex Setting Date and Time: The Foundation
Before setting your dual time zones, ensure you understand the basic time and date setting. This involves using the winding crown, which operates in different positions to control various functions.
Rolex Winding Crown Position Chart:
Understanding the crown positions is paramount. Most Rolex watches, including the GMT-Master II, follow a similar system:
* Position 1 (Screwed Down): This is the default position, protecting the watch from water and dust. In this position, the crown is fully screwed into the case. This should be your starting point before any adjustments.
* Position 2 (Unscrewed, First Click): Unscrew the crown carefully. In this position, you can adjust the date. Turning the crown clockwise advances the date, while turning it counter-clockwise reverses it. This is usually done when changing the time across midnight.
* Position 3 (Unscrewed, Second Click): Further unscrewing the crown to the second click allows you to adjust the time. Turning the crown clockwise advances the time, and counter-clockwise reverses it. The hour, minute, and second hands will all move accordingly.
Setting the Time and Date (Local Time):
1. Unscrew the crown: Carefully unscrew the crown counter-clockwise to position 1.
2. Pull the crown to position 3: Pull the crown out to the second click.
3. Set the time: Carefully adjust the hour, minute, and second hands to the correct local time using the crown.
4. Set the date (if necessary): If adjusting the time crosses midnight, pull the crown to position 2 and set the date to the correct day.
5. Push the crown back: Carefully push the crown back into position 1 and screw it down tightly.
