The Rolex Datejust, a timeless icon of horological excellence, is renowned for its precision and elegance. However, understanding how to correctly set the date and time, particularly on older models, requires a little more than a cursory glance at the watch face. This comprehensive guide will walk you through the process, differentiating between models with and without the quickset date function, addressing common issues, and offering advice for maintaining your precious timepiece.
Understanding the Generations of Rolex Datejust Movements
Before diving into the setting procedures, it's crucial to understand the evolution of the Datejust movement. This significantly impacts how you adjust the date and time. The key distinction lies in the presence or absence of the "quickset" date function.
* Pre-Caliber 3035 Datejusts (Non-Quickset): Vintage Rolex Datejust watches manufactured before the introduction of the Caliber 3035 movement (roughly late 1970s onwards) lack the quickset date function. This means you cannot directly advance or retard the date independently. Setting the date on these models requires a more involved process.
* Post-Caliber 3035 Datejusts (Quickset): Datejusts equipped with the Caliber 3035 and subsequent movements incorporate a quickset date mechanism. This makes adjusting the date significantly easier and faster.
Setting the Date and Time on a Non-Quickset Rolex Datejust (Pre-Caliber 3035)
Setting the date and time on a non-quickset Datejust requires patience and precision. The absence of a quickset function necessitates advancing or retarding the date by manually rotating the hour hand.
Step-by-Step Instructions:
1. Identify the Crown: Locate the crown (winding stem) on the right side of your watch case. It's usually slightly larger than the other pushers or buttons.
2. Unscrew and Pull the Crown: Carefully unscrew the crown counter-clockwise. The number of turns required to unscrew the crown varies depending on the model; usually, it's one or two turns. Once unscrewed, gently pull the crown out to the first position (click). This position allows you to adjust the time.
3. Setting the Time: Rotate the crown clockwise to advance the time or counter-clockwise to retard it. Pay close attention to the movement of the hour, minute, and second hands. Ensure the time is accurately set to the desired hour and minute.
4. Setting the Date: This is where the process differs from quickset models. To advance the date, you must rotate the hour hand completely around (twelve hours). The date will change as the hour hand passes midnight. To retard the date, you must rotate the hour hand backward twelve hours. This process needs to be repeated for each day you wish to adjust. For example, to advance the date by three days, you need to rotate the hour hand three complete cycles of twelve hours each.
5. Push the Crown Back In: Once the time and date are correctly set, gently push the crown back into its original position. Ensure it is fully screwed down to maintain the watch's water resistance.
Important Considerations for Non-Quickset Models:
* Patience is Key: This process is time-consuming, especially for larger date adjustments. Be patient and methodical.
* Avoid Force: Never force the crown. If you encounter resistance, stop and check your technique.
