The Rolex Oyster Perpetual Datejust is a timeless classic, renowned for its precision, durability, and elegant design. Owning one is a significant achievement, but understanding its functionality, particularly how to accurately adjust the time, is crucial for enjoying your investment fully. This comprehensive guide will walk you through the process of setting the time, date, and other functions on your Rolex Oyster Perpetual Datejust, covering everything from the basics to troubleshooting potential issues. We'll also touch upon some related topics, such as identifying genuine Rolex watches and understanding their value.
Understanding the Components:
Before we delve into the adjustment process, let's familiarize ourselves with the key components involved:
* Hour Hand: The shorter hand indicating the hour.
* Minute Hand: The longer hand indicating the minutes.
* Seconds Hand: The thinnest hand indicating the seconds. Its smooth, continuous movement is a hallmark of a well-maintained mechanical watch.
* Date Window: Located typically at 3 o'clock, this window displays the current date of the month.
* Twinlock Winding Crown with Double Waterproofness System: This is the crucial component for adjusting the time and date. The Twinlock system, a characteristic feature of Rolex, enhances the watch's water resistance. Its screw-down design provides a secure seal against water ingress.
Adjusting the Time:
The process of adjusting the time on your Rolex Oyster Perpetual Datejust is straightforward but requires a gentle touch to avoid damaging the delicate mechanism.
1. Unscrew the Crown: Carefully unscrew the Twinlock crown by turning it counter-clockwise until you feel it release. This may require a little effort, but avoid forcing it. If it feels excessively stiff, consult a professional watchmaker.
2. Pull Out the Crown: Once the crown is unscrewed, gently pull it out to the first position (approximately one click). This position activates the time-setting function.
3. Setting the Time: Turn the crown clockwise to adjust the hour and minute hands. The movement of the hands should be smooth and precise. Remember that the minute hand should be set first to the correct minute, then the hour hand to the correct hour. Setting the hour hand will automatically move the minute hand, but setting the minute hand independently will not affect the hour hand.
4. Push the Crown Back In: Once the time is correctly set, gently push the crown back into its original position. You should feel distinct clicks as it goes back in. Ensure the crown is fully pushed in and then screw it back down tightly, turning it clockwise until it's firmly seated. This seals the watch and maintains its water resistance.
Adjusting the Date:
Setting the date on your Rolex Oyster Perpetual Datejust requires a slightly different approach:
1. Unscrew and Pull the Crown: Follow steps 1 and 2 from the time-setting instructions above.
2. Pull the Crown to the Second Position: Pull the crown out to the second position (approximately two clicks). This activates the date-setting function.
3. Setting the Date: Turn the crown clockwise to advance the date. The date will change one day at a time. You'll need to rotate the crown several times to set the date to the correct number.
4. Push the Crown Back In: Once the date is set, gently push the crown back in to the first position and then fully into its original position, screwing it down tightly.
