The Rolex Datejust, a timeless icon of horological excellence, combines classic elegance with robust functionality. Its precise movement, coupled with the iconic cyclops magnifying lens over the date window, makes it a coveted timepiece for generations. However, even the most sophisticated watch requires occasional adjustments. This comprehensive guide will walk you through the process of adjusting your Rolex Datejust, covering the hour, minute, second hands, and the date, while emphasizing the careful handling required for this prestigious timepiece.
Understanding Your Rolex Datejust's Crown:
Before diving into the adjustment process, it's crucial to understand the role of the Twinlock winding crown, a hallmark of Rolex's commitment to waterproofness and durability. The Twinlock crown, with its double waterproofness system, is the key to setting your Datejust. It operates in different positions, each controlling a specific function. Improper handling can damage the crown or the internal mechanism, so proceed with caution and gentleness.
Setting the Time: Hour, Minute, and Second Hands
1. Unscrew the Crown: Gently unscrew the winding crown by turning it counter-clockwise. You'll feel a distinct resistance as you pass the first seal. Continue turning until the crown is fully unscrewed. Avoid forceful twisting, as this could damage the crown or its seals.
2. Pull Out the Crown: Once unscrewed, carefully pull the crown out to its first position (approximately one click). You'll notice a slight resistance as it clicks into place. In this position, only the hour and minute hands are adjustable.
3. Setting the Time: Turn the crown clockwise to advance the hour and minute hands. Turn it counter-clockwise to move them backward. Take your time and ensure the hands are precisely set to the correct time. Remember, setting the time involves adjusting the hour hand first and then the minute hand, ensuring accuracy.
4. Pushing the Crown Back In: Once the time is correctly set, gently push the crown back into its original position. You should feel it click back into place. Ensure it's fully seated.
5. Screw the Crown Back: Carefully screw the crown back in by turning it clockwise until it's fully tightened. You'll feel the resistance of the seals as you screw it back in. This is crucial for maintaining the watch's water resistance.
Setting the Date:
Setting the date on your Rolex Datejust requires a slightly different procedure:
1. Unscrew the Crown: As with setting the time, gently unscrew the winding crown counter-clockwise until it's fully unscrewed.
2. Pull Out the Crown: Pull the crown out to its second position (approximately two clicks). You will feel distinct clicks indicating the different positions. In this position, both the time and the date are adjustable.
3. Setting the Date: Turn the crown clockwise to advance the date. You'll see the date change in the date window. Turn the crown counter-clockwise to move the date backward.
4. Pushing the Crown Back In: Once the date is correctly set, gently push the crown back to its first position (one click), and then fully push it back into its original, fully screwed-in position.
Important Considerations When Adjusting Your Rolex Datejust:
* Never adjust the date between 9 pm and 3 am: This is a critical precaution to prevent damage to the date-changing mechanism. The internal components are engaged during this period, and attempting to adjust the date can cause damage.
