The Rolex Submariner, a legendary dive watch renowned for its robustness and precision, features a date complication in many of its models. Knowing how to correctly adjust the date is crucial for maintaining the accuracy and longevity of your timepiece. This comprehensive guide will walk you through the process, addressing common questions and misconceptions, and providing detailed instructions to ensure you handle your Submariner with the care it deserves. We'll explore the mechanics involved, referencing various resources like the Rolex Submariner manual PDF, Rolex Submariner watch instructions, and other relevant guides, to provide a complete understanding of date adjustment.
Understanding the Submariner's Crown and its Functions:
The key to setting the date on your Rolex Submariner lies in its winding crown. This seemingly simple component is a marvel of engineering, responsible for multiple functions beyond simply winding the mainspring. The crown's functionality is often described in four positions, although the precise feel and resistance may vary slightly depending on the specific Submariner model and its age.
Position 1: Screwed Down (Fully Tightened): In this position, the crown is fully screwed into the case, providing water resistance. This is the normal operating position when the watch is not being adjusted. Attempting to adjust the time or date while the crown is in this position will not work and could potentially damage the mechanism.
Position 2: Unscrewed (First Unscrew): Gently unscrew the crown counter-clockwise. You should feel a slight resistance as you begin to unscrew it. This first unscrew doesn't yet activate any timekeeping functions. It simply prepares the crown for further adjustment.
Position 3: Time Setting: After unscrewing the crown to the first unscrew position, unscrew it further. This is usually a more noticeable unscrew. This second unscrew is the time-setting position. Turning the crown will now move the hour, minute, and second hands. Crucially, avoid rapidly changing the time, particularly across midnight. Gradual adjustment is recommended to prevent potential damage to the date-setting mechanism.
Position 4: Date Setting: This position is often described as the quick-set date position and is generally reached after a further unscrew from the time-setting position. The exact method of reaching this position can vary slightly between Submariner models. Some models might require a half-turn or a full turn after reaching the time-setting position (Position 3). Once in this position, turning the crown will advance the date. You should feel a distinct difference in the resistance compared to the time-setting position.
Step-by-Step Guide to Setting the Date:
1. Ensure the crown is in Position 1: Begin by making sure the crown is fully screwed down and the watch is in its normal operating mode.
2. Unscrew the crown: Carefully unscrew the crown counter-clockwise, first to the first unscrew position and then to the time-setting position. Pay attention to the resistance; you should feel distinct clicks or changes in resistance indicating the different positions.
