The Rolex Oyster Perpetual Datejust, a timeless icon of horological excellence, boasts a sophisticated mechanism that, while generally robust and reliable, requires a slightly different approach to setting depending on the watch's age and features. Understanding how to correctly set your Datejust is crucial for maintaining its accuracy and longevity. This comprehensive guide will walk you through the process, addressing the key differences between older models lacking the quickset date function and their more modern counterparts. We'll also touch upon important considerations for authenticating your timepiece and understanding its value.
Understanding the Quickset Date Feature
The defining difference in setting a Rolex Datejust lies in the presence or absence of the quickset date feature. This feature allows you to adjust the date independently of the time, making the process significantly faster and easier. Introduced later in the Datejust's production history, this feature is a game-changer for ease of use.
Setting a Rolex Datejust with Quickset Date
Most modern Rolex Oyster Perpetual Datejust models incorporate the quickset date function. To set the date on these watches, follow these steps:
1. Unscrew the crown: Locate the crown (the knob on the side of the watch) and gently unscrew it counter-clockwise until it is fully extended to the first position. Be careful not to force it.
2. Set the date: Turn the crown clockwise to advance the date. Each full rotation of the crown will advance the date by one day. Continue turning until the correct date is displayed.
3. Return the crown to its position: Once the date is correctly set, push the crown back in and gently screw it back clockwise until it is securely fastened. This ensures the water resistance of your watch.
Setting an Older Rolex Datejust (Without Quickset Date)
Earlier models of the Rolex Datejust, often highly sought-after by collectors as *older Rolex Oyster Perpetual Datejust* models, did not have this convenient quickset function. Setting the date on these watches requires a more involved process:
1. Unscrew the crown: As with the quickset models, gently unscrew the crown counter-clockwise to its first position.
2. Advance the time: Instead of directly setting the date, you must advance the time past midnight. Turn the crown clockwise to move the hour and minute hands. You will need to advance the time until the date changes to the correct day. This process can take some time, especially if you need to adjust the date by several days.
3. Return the crown to its position: Once the date has changed to the correct day, push the crown back in and screw it back clockwise to secure it.
Important Considerations:
* Avoid setting the date between 9 PM and 3 AM: The date change mechanism is typically activated during this period. Setting the date within this window can potentially damage the movement. It's best to avoid this time frame altogether.
* Gentle handling: Always handle your Rolex Datejust with care. Avoid excessive force when winding or setting the crown.
* Regular servicing: Regular servicing by an authorized Rolex service center is crucial for maintaining the accuracy and longevity of your watch. This ensures that all components are functioning optimally.
