The Rolex GMT-Master, a watch synonymous with global travel and sophisticated style, offers a unique complication: a second time zone. This guide will comprehensively cover the use of this iconic timepiece, from setting the time and date to mastering the dual-time functionality. We’ll delve into specific models, addressing questions about the GMT-Master II and its various iterations.
I. Understanding the Rolex GMT-Master's Dual-Time Functionality
At its core, the Rolex GMT-Master's functionality revolves around its independently adjustable 24-hour hand. Unlike a standard watch with only an hour, minute, and second hand, the GMT-Master incorporates this additional hand, allowing you to track two time zones simultaneously. The secret lies in the independently rotating bezel.
The bezel, graduated in 24 hours (typically with alternating black and red markings representing night and day), is the key to utilizing the second time zone. To read a second time zone, simply rotate the bezel in either direction to correspond with the number of hours ahead or behind it is of your current time zone. For example, if your home time is London (GMT) and you travel to New York (EST, 5 hours behind), you would rotate the bezel counter-clockwise by five hours. The 24-hour hand, which remains fixed to your home time, will then point to the current time in New York on the bezel. The standard hour hand will always display your local time.
This system offers unparalleled flexibility. You can track your home time, a destination time, or even a third time zone using clever mental calculations – for example, using the bezel to represent the difference between your local time and a business partner's time zone.
II. Setting a Rolex GMT-Master (Setting a Rolex Watch GMT)
Setting a Rolex GMT-Master involves several steps, and understanding the process is crucial for accurate timekeeping. This section covers the setting of both the time and the date.
A. Setting the Time:
1. Unscrew the crown: Locate the crown (the winding knob) on the side of your watch. Unscrew it carefully by turning it counter-clockwise until it is loose. Be gentle to avoid damaging the crown or threads.
2. Pull out the crown: Pull the crown out to its first position (usually about one click). This allows you to adjust the time.
3. Setting the hour, minute, and second hands: Turn the crown clockwise to set the hour, minute, and second hands to the correct time in your primary time zone.
4. Push the crown back in: Once the time is correctly set, gently push the crown back into its original position. Ensure that the crown is fully screwed back down to maintain the watch's water resistance.
B. Setting the Date:
The date on a Rolex GMT-Master is typically adjusted by pulling the crown out to its second position (usually a second click). This allows you to adjust the date by turning the crown clockwise or counter-clockwise. Note that you can only adjust the date between approximately 9 PM and 3 AM. Attempting to adjust it outside this window may damage the movement. Once the date is correct, push the crown back to its original position and screw it back down tightly.
