The Rolex Oyster Perpetual Datejust is a timepiece of elegance and precision, beloved by watch enthusiasts around the world. Its sleek design, robust construction, and accurate movement make it a staple in Rolex’s storied lineup. However, like any high-quality watch, there may come a time when you need to adjust the date. Whether you’ve recently purchased your Datejust or you’ve had it for years, knowing how to change the date correctly is an essential skill. In this guide, we’ll walk you through the process of changing the date on your Rolex Oyster Perpetual Datejust, ensuring you do so with ease and precision.
Understanding Your Rolex Oyster Perpetual Datejust
Before diving into the steps to change the date, it’s important to understand the basic mechanics of your Rolex Oyster Perpetual Datejust. This watch is powered by a self-winding mechanical movement, which means it uses the motion of your wrist to wind the watch automatically. The Datejust features a date display at the 3 o’clock position, visible through a Cyclops lens—a magnifying glass built into the sapphire crystal glass, making the date easy to read.
The Rolex Oyster case, known for its robustness and elegance, houses the movement and ensures water resistance up to 100 meters (330 feet). The Twinlock winding crown, with its double waterproofness system, adds an extra layer of protection, securing the watch against water and dust. Understanding these features will help you appreciate the intricacies of your watch and perform the date change with confidence.
Preparing to Change the Date
Before you begin adjusting the date on your Rolex Oyster Perpetual Datejust, there are a few preparations you need to make. First, ensure that you have a clear and uninterrupted period to perform the task. This will help you focus and avoid any accidental mishaps.
Second, locate your watch’s winding crown. The winding crown is the small knob on the right-hand side of the watch case. It has two positions: a screwed-down position (position 0) and an unscrewed position (position 1 and 2). When the crown is in the screwed-down position, the watch is waterproof. To access the date-setting function, you’ll need to unscrew the crown and move it to the appropriate position.
It’s also crucial to note the time of day when you plan to change the date. Rolex recommends avoiding adjusting the date between 8 PM and 3 AM. During this period, the watch’s internal mechanisms are in the process of changing the date, and adjusting it manually during this time could potentially damage the movement. So, choose a time outside of these hours to ensure a smooth and safe date change.
Changing the Date: A Step-by-Step Conceptual Guide
While we won’t list the steps in a numbered format, we’ll guide you through the process conceptually, making it easy to follow along.
1. Unscrewing the Crown
Begin by gently unscrewing the winding crown. This is done by turning it counterclockwise until it clicks into the first unscrewed position (position 1). Take care not to force it, as the crown is designed to screw down securely to maintain waterproofness. Once the crown is unscrewed, you can move it to the second position (position 2) by pulling it out slightly further. This position allows you to adjust both the time and the date.
2. Adjusting the Time First
Before changing the date, it’s good practice to adjust the time first. This ensures that the hands are in the correct position, making it easier to set the date accurately. Rotate the crown clockwise in position 2 to move the hands. As you do this, you’ll notice that the second hand moves in smooth, continuous motion, while the hour and minute hands move in increments.
If you’re adjusting the time from a setting that’s significantly different from the current time, be mindful of the date change mechanism. If you’re moving the hands past midnight, the date should change automatically. However, to avoid any confusion, it’s best to set the time to around 6 or 7 AM, ensuring that the date hasn’t changed yet. This gives you a clear window to adjust the date without worrying about the time-date synchronization.
3. Setting the Correct Date
Now that the time is set, you can move on to adjusting the date. With the crown still in position 2, rotate it clockwise or counterclockwise to change the date. The date will change incrementally with each rotation, allowing you to set it to the correct day.
It’s important to note that if you’re adjusting the date from a previous month with fewer days (e.g., from February 28th to March 1st), you may need to turn the crown several times to advance the date past the end of the shorter month. Similarly, when adjusting from a month with 31 days to one with 30 or fewer, you may need to be careful not to overshoot the correct date.
As you adjust the date, you’ll notice that the hands continue to move. This is normal, as the movement is interconnected. However, keep in mind that you should not change the date while the hands are between 8 PM and 3 AM, as this could harm the mechanism.
4. Fine-Tuning the Time
Once the date is set correctly, you can fine-tune the time to the exact hour and minute. Rotate the crown clockwise in position 2 to move the hour and minute hands to the precise time. Remember to avoid moving the hands past midnight, as this will cause the date to change again.
If you’re setting the time to an afternoon hour, ensure that the date has already changed once. If not, let the hands pass midnight naturally by continuing to rotate the crown clockwise. Once the date changes, you can then set the exact time for the afternoon.
5. Securing the Crown
With the date and time set correctly, it’s time to secure the winding crown. Push the crown back into position 1 (the unscrewed but not pulled-out position). Then, screw it down clockwise until it clicks securely into place. This ensures that your Rolex Oyster Perpetual Datejust is once again waterproof and protected against dust and debris.
Final Thoughts and Maintenance Tips
Changing the date on your Rolex Oyster Perpetual Datejust is a straightforward process once you understand the mechanics of the watch. By following the preparations and steps outlined in this guide, you can adjust the date with confidence, ensuring your watch remains accurate and reliable.
However, it’s important to remember that, like any precision instrument, your Rolex requires regular maintenance to keep it in optimal condition. Rolex recommends sending your watch to an authorized Rolex service center every few years for a thorough inspection and cleaning. This includes checking the movement, lubricating parts, and ensuring the watch maintains its water resistance.
In addition to professional maintenance, there are a few things you can do to keep your Rolex in good condition. Avoid exposing your watch to extreme temperatures or harsh chemicals, as these can damage the movement and case. Regularly clean the watch with a soft cloth and warm water to remove dirt and grime. And, if you’re not wearing your watch, store it in a cool, dry place to prevent damage from moisture and dust.
Conclusion
Changing the date on your Rolex Oyster Perpetual Datejust is a simple task that requires a bit of care and precision. By following the steps outlined in this guide and maintaining your watch regularly, you can ensure that your Rolex remains a timeless symbol of elegance and precision for years to come.
