Many Rolex owners cherish their timepieces not only for their prestige but also for their robust reliability. However, even these meticulously crafted watches can occasionally present issues. One common problem reported by owners, particularly those with vintage models, is a problematic date change mechanism. This article delves into the intricacies of Rolex date change mechanisms, explores the common causes of date-setting difficulties, and provides guidance on troubleshooting and preventative maintenance. We will also address specific user queries related to adjusting various Rolex models, including the Submariner, Datejust, and Day-Date.
My Experience with a Submariner 16800 Date Change Issue
Before diving into the technical aspects, I want to share a personal experience that highlights this problem. I previously owned a Submariner 16800 that exhibited a date change issue before it underwent servicing. The problem was most noticeable when the power reserve was low. While the date would advance, it would often "hang" approximately three-quarters of the way through the change, leaving the date partially obscured and visually displeasing. This wasn't a complete failure to change the date, but rather an incomplete or sluggish transition. This experience underscores the importance of understanding the mechanics of the date-setting mechanism and the potential impact of factors like power reserve on its performance.
Rolex Setting Date and Time: Understanding the Crown Positions
The Rolex crown, that iconic winding stem, is the key to setting the time and date on your Rolex watch. Unlike many modern watches with separate buttons for date adjustment, Rolex utilizes the crown's various positions to perform these functions. Typically, there are three main positions:
* Position 1 (Screw-down): This is the fully screwed-down position, providing water resistance. It's the position the crown should be in when not adjusting the watch. Attempting to adjust the time or date with the crown screwed down could damage the movement.
* Position 2 (Unscrewed and First Click): Unscrewing the crown to the first click allows you to adjust the time. Turning the crown clockwise will advance the time, while turning it counterclockwise will rewind it.
* Position 3 (Unscrewed and Second Click): Unscrewing the crown further to the second click (or sometimes a more distinct 'click') enables date adjustment. Turning the crown clockwise will advance the date, and turning it counterclockwise will rewind the date. The exact feel and number of clicks may vary slightly depending on the model and year of manufacture.
How to Adjust Rolex Datejust, Rolex Date, and Rolex Time:
The process for adjusting the time and date is largely consistent across many Rolex models, including the Datejust, although minor variations might exist due to specific movement variations. Always refer to your watch's manual for specific instructions. However, the general principles remain the same:
1. Unscrew the Crown: Carefully unscrew the crown counterclockwise until you feel the first click, then the second click (if necessary).
2. Adjust the Time: In the first click position, rotate the crown to adjust the hour and minute hands.
3. Adjust the Date: In the second click position, rotate the crown to adjust the date. Remember to advance the date only during the appropriate time window, typically between 9 PM and 3 AM. Attempting to change the date outside this window can cause damage to the movement.
4. Screw Down the Crown: Once the time and date are correctly set, carefully screw the crown back into its fully tightened position (Position 1). This is crucial for maintaining the water resistance of your watch.
