The Rolex GMT-Master II, a watch synonymous with global travel and aviation heritage, boasts a unique complication: the independently adjustable 24-hour hand, typically displayed in red. This hand allows the wearer to track a second time zone simultaneously with local time, a feature that has solidified its position as a coveted timepiece among discerning collectors and professional pilots alike. However, understanding how to correctly set this crucial red hand is paramount to fully utilizing the watch's functionality. This article will delve into the intricacies of setting the GMT hand on your Rolex GMT-Master II, covering various models and addressing common user queries. We will also explore some of the most popular GMT-Master II variations, including the Sprite, the green bezel models, and the Oystersteel versions, touching upon their pricing and desirability within the collector's market.
Understanding the GMT-Master II Movement:
Before we dive into the setting procedure, it's crucial to grasp the underlying mechanics. The GMT-Master II utilizes a sophisticated movement, typically a calibre 3186 or 3285 (depending on the model), which allows for independent adjustment of the hour hand and the 24-hour hand (the red hand). This means you can change the local time without affecting the second time zone, and vice-versa. This contrasts with simpler GMT movements where adjusting the hour hand also affects the 24-hour hand.
Setting the Red Hand: A Step-by-Step Guide:
The process of setting the red hand is straightforward but requires careful attention to detail. Refer to your Rolex GMT-Master II owner's manual (available for download online – as mentioned, you can find it by searching "View and Download Rolex GMT-Master II owner's manual online.") for specific instructions pertaining to your watch's model and calibre. However, the general procedure is as follows:
1. Unscrew the crown: Locate the crown (the winding knob) on the right side of your watch case. Gently unscrew it by turning it counter-clockwise until it comes free.
2. Pull out the crown to position 2: Pull the crown out to the second position. This will usually require a slight but firm pull. You will feel distinct clicks as the crown moves through its positions. Position 2 is the position where you can adjust the hour hand and the 24-hour (red) hand independently.
3. Adjusting the red hand: Now, carefully turn the crown clockwise or counter-clockwise. This will move the 24-hour hand, allowing you to set it to the desired time in your second time zone. Remember, the red hand moves in increments of one hour.
4. Adjusting the hour hand (local time): Once the red hand (GMT time) is set, you can adjust the hour hand (local time) by rotating the crown in the same position. The hour hand will move independently of the red hand.
5. Push the crown back in: Once both hands are correctly set, gently push the crown back into its original position. You should feel distinct clicks as it returns to its fully screwed-in position. Ensure the crown is fully screwed down to maintain the watch's water resistance.
