The Rolex Oyster Perpetual Datejust is a timeless icon, a symbol of prestige and enduring elegance. Its sophisticated design and robust engineering have cemented its place as one of the most sought-after watches globally. However, even the most seasoned watch enthusiast might occasionally find themselves grappling with the intricacies of winding and setting their Datejust, particularly the process described as "aufziehen," the German word for winding. This article will comprehensively guide you through the process of winding and setting the date on your Rolex Oyster Perpetual Datejust, addressing common questions and concerns. We'll also delve into the broader world of Datejust ownership, touching upon topics like purchasing a genuine model, differentiating it from counterfeits, exploring price trends, and appreciating the history of this iconic timepiece.
Understanding "Aufziehen" and the Winding Crown
The term "aufziehen," as mentioned in the prompt, directly translates to "winding up." This refers to the process of manually winding the mainspring of your Rolex Oyster Perpetual Datejust. Unlike self-winding or automatic watches that utilize the movement of your wrist to power the mechanism, the Datejust, while often available in self-winding versions, also has a manual winding capability. This allows you to manually wind the watch to ensure optimal power reserve, especially if it hasn't been worn for a period.
The winding process begins with the screw-down crown. This crown, a hallmark of Rolex's Oyster case, is designed for water resistance. Before attempting to wind or set the time, you must unscrew the crown by turning it counter-clockwise until it is loose. You will feel distinct clicks as you unscrew it. Once unscrewed, you can pull the crown out to its first position (position 1). This position is crucial for setting the date.
Setting the Date on Your Rolex Oyster Perpetual Datejust
Once the crown is in position 1, you can adjust the date. The direction you turn the crown to adjust the date depends on your specific model. Some models require clockwise rotation, others counter-clockwise. There is no universal rule; you must experiment carefully to determine the correct direction for your watch. Turning the crown will advance or retard the date, typically advancing one day for each complete rotation. Important: Avoid rapidly turning the crown, as this can damage the date mechanism. Gentle, deliberate turns are key. Once the date is correctly set, push the crown back in to its original position and screw it back in tightly.
Troubleshooting and Common Issues
Despite its robust construction, occasional issues might arise during the winding and setting process. Here are some common problems and their solutions:
* Crown won't unscrew: This could be due to the crown being tightly screwed or the presence of debris. Try gently turning the crown counter-clockwise while applying slight pressure. If the problem persists, consult a professional watchmaker.
* Date doesn't change: Ensure the crown is correctly pulled out to position 1. Try gently turning the crown both clockwise and counter-clockwise. If the date still doesn't change, the date mechanism might require servicing.
* Crown feels stiff or difficult to turn: This could indicate a need for lubrication or a more significant mechanical issue. Do not force the crown; consult a watchmaker immediately.
* Date jumps erratically: This is a clear indication of a problem within the date mechanism and requires professional attention.
