Mastering Time: A Comprehensive Guide to Setting Your Rolex GMT-Master
So, you’ve acquired a Rolex GMT-Master, a horological icon celebrated for its ability to display multiple time zones simultaneously. But how do you actually set this marvel of engineering? Let’s dive in.
How to Set a Rolex GMT-Master: A Step-by-Step Guide
The process varies slightly depending on the specific GMT-Master model you own (vintage vs. modern, with or without independent hour hand adjustment), but the core principle remains the same. This guide will cover the modern GMT-Master II with the independent 24-hour hand and quickset date.
Unscrew the Crown: Locate the crown on the right side of the watch case. Gently unscrew the crown counterclockwise until it springs out to its first position. Do not pull it out yet.
Winding (If Necessary): If the watch has stopped, this first position is for winding. Turn the crown clockwise to wind the movement. A few rotations should be sufficient if it’s only been stopped for a short while. If it’s been stopped for a longer period, wind it 30-40 times.
Setting the Date (First Crown Position – Quickset Date): Pull the crown out to the first pulled-out position (one click out). This is the quickset date function. Rotate the crown clockwise to advance the date. Note that the date change happens instantaneously at midnight, so don’t worry if the date isn’t perfectly aligned in the middle of the window during the setting process.
Setting the Local Hour Hand (Second Crown Position – Independent Hour Hand Adjustment): Pull the crown out to the second pulled-out position (two clicks out). In this position, you can independently adjust the local hour hand forward or backward in one-hour increments. This is the key feature for travelers. Each click changes the local time by one hour. Rotate the crown until the local hour hand displays the correct local time, making sure to account for AM/PM. The 24-hour hand will remain fixed to the home time zone during this process. The date will also change when you pass midnight (either advancing or going back).
Setting the Minutes and Seconds (Third Crown Position – Hacking Seconds): Pull the crown out to the third and final pulled-out position (three clicks out). This stops the seconds hand (a feature known as “hacking seconds”), allowing for precise time setting. Rotate the crown in either direction to set the minutes and seconds accurately. Use an accurate time source (like a smartphone or online atomic clock) for reference.
Synchronize and Push In the Crown: Once the time is set to the exact second, push the crown all the way back in. As the seconds hand begins to move again, double-check the synchronisation with your reference time.
Screw Down the Crown: Once pushed in, screw the crown clockwise until it is snug but not overly tight. This ensures the watch’s water resistance.
Setting the 24-Hour Bezel: This is the final step. The rotating bezel is used to display a third time zone. To set it, determine the time difference between your home time zone (displayed by the 24-hour hand) and the desired third time zone. Rotate the bezel until the corresponding hour marker on the bezel aligns with the hour hand. For instance, if your 24-hour hand shows 4:00 PM and you want to know the time in a location 5 hours ahead, rotate the bezel until the “9” is aligned with the 24-hour hand. This will visually show that the time in that location is 9:00 PM.
That’s it! Your Rolex GMT-Master is now properly set. Mastering these steps will allow you to easily transition between time zones with confidence.
Frequently Asked Questions (FAQs) About Setting Your Rolex GMT-Master
Here are some frequently asked questions to further assist you in understanding the functionality and maintenance of your Rolex GMT-Master.
Q1: What is the difference between the GMT hand and the hour hand?
The hour hand displays the local time, the time zone you are currently in. The GMT hand, also called the 24-hour hand, displays your home time zone or a second time zone of your choice. The rotating bezel allows you to track a third time zone.
Q2: How do I set the GMT-Master II if I don’t travel?
Even if you don’t travel, the GMT-Master II is still a fantastic timepiece. You can set the 24-hour hand to display your local time and use the rotating bezel to track a different time zone – perhaps that of a relative or business associate. Or, simply use the 24-hour hand as a visual AM/PM indicator.
Q3: What if my Rolex GMT-Master II is an older model without the independent hour hand?
Older GMT-Master models require a slightly different setting procedure. In this case, when you pull the crown to the third position (full pull-out), both the hour hand and the 24-hour hand are linked and move together. To set the 24-hour hand, you first set the regular hour hand and then use the rotating bezel to align the desired time zone to the 24-hour hand.
Q4: Can I damage my Rolex by setting the date between 9 PM and 3 AM?
While it’s generally advised to avoid setting the date during this period (often called the “danger zone”), the modern GMT-Master movements are quite robust. However, repeatedly forcing the quickset date during these hours can potentially strain the mechanism over time. Exercise caution and avoid it when possible.
Q5: How often should I have my Rolex GMT-Master serviced?
Rolex recommends a service interval of approximately every 10 years. However, this can vary depending on usage and environmental factors. If you notice any performance issues, such as inaccuracies or difficulty winding, it’s best to have it checked by a certified Rolex service center.
Q6: What does “hacking seconds” mean?
“Hacking seconds” refers to the feature where the seconds hand stops when the crown is pulled out to the third position. This allows for precise time setting and synchronization with a reference time source.
Q7: Is the rotating bezel on the GMT-Master II bidirectional?
Yes, the rotating bezel on the GMT-Master II is bidirectional, meaning it can be rotated both clockwise and counterclockwise. This allows for easy and quick adjustment when tracking different time zones.
Q8: How do I maintain the water resistance of my Rolex GMT-Master II?
Always ensure that the crown is fully screwed down after setting the time or date. Avoid exposing your watch to extreme temperature changes or harsh chemicals. Have the water resistance tested annually, especially if you frequently wear the watch during water activities.
Q9: What should I do if my Rolex GMT-Master II stops running?
If your Rolex GMT-Master II stops running, first, try winding it manually by turning the crown clockwise in the first position (crown unscrewed, but not pulled out). If it still doesn’t start, it may require professional servicing. Don’t attempt to open the watch yourself, as this could damage the movement.
Q10: How can I find a reputable Rolex service center?
Rolex maintains a network of authorized service centers worldwide. You can find a list of these service centers on the official Rolex website. Ensure that the service center you choose is authorized to perform repairs and maintenance on Rolex watches.
Q11: Can I change the bracelet or strap on my Rolex GMT-Master II myself?
While it is possible to change the bracelet or strap yourself using the appropriate tools, it is generally recommended to have it done by a professional. Incorrect removal or installation can damage the watch case, bracelet, or strap.
Q12: What’s the best way to store my Rolex GMT-Master II when I’m not wearing it?
When you’re not wearing your Rolex GMT-Master II, store it in a safe and dry place, preferably in its original box or a watch winder. Avoid storing it in direct sunlight or near strong magnetic fields. If storing it for an extended period, consider winding it periodically to keep the movement lubricated.
