Setting the time on your Rolex Submariner is a seemingly simple process, but understanding the nuances of its Triplock crown and the delicate mechanism within ensures the longevity and accuracy of your prized possession. This comprehensive guide will walk you through the procedure, addressing common questions and offering insights applicable to other Rolex models, including the Datejust, Day-Date, and Oyster Perpetual. We'll cover everything from the basics of adjusting the time and date to more advanced techniques, ensuring your Rolex remains a precise and reliable timekeeping instrument.
Understanding the Rolex Submariner Crown:
The Rolex Submariner's crown is not just a time-setting mechanism; it's a crucial component of its water resistance. The Triplock winding crown system, exclusive to Rolex, features three sealing zones, providing exceptional water resistance down to significant depths. Properly using this crown is essential not only for setting the time but also for preserving the watch's integrity. Improper handling can lead to damage to the seals, compromising water resistance.
Step-by-Step Guide to Setting the Time on a Rolex Submariner:
1. Unscrew the Crown: This is the first and arguably most crucial step. Gently unscrew the crown by turning it counter-clockwise. You'll feel distinct clicks as the crown unwinds. Do not force it; if it feels resistant, stop and double-check you're turning in the correct direction. The number of clicks will vary slightly depending on the model year, but you'll typically feel between one and two full rotations before the crown comes free. This action releases the crown from its sealed position, preparing it for time adjustment.
2. Pull Out the Crown: Once the crown is unscrewed, gently pull it out. You'll feel distinct resistance points as you pull. The Rolex Submariner crown typically has three positions:
* Position 1 (Slightly pulled): This position allows you to set the date. Turning the crown clockwise will advance the date. Turning it counter-clockwise will rewind the date. Be mindful not to adjust the date between 9 PM and 3 AM, as this is when the date change mechanism is active. Attempting to change the date during this period can damage the internal components.
* Position 2 (Pulled further): This is the position for setting the time. Turning the crown clockwise will advance the time, and counter-clockwise will rewind it. You can adjust the hour and minute hands independently. Remember that turning the crown rapidly can potentially damage the delicate internal gear train. Make small, controlled adjustments.
* Position 3 (Fully pulled, usually not present in Submariner): This position is not typically used on a Submariner for time setting. Some Rolex models use this position for quick date setting adjustments.
3. Setting the Time and Date: In position 2, carefully adjust the hour and minute hands to the correct time. Remember to move the hands smoothly and avoid any jerky motions. After adjusting the time, if necessary, return the crown to position 1 and adjust the date.
4. Push and Screw the Crown Back In: Once the time and date are correctly set, gently push the crown back in until it clicks into its fully seated position. Then, carefully screw the crown back in clockwise until it's tightly secured. You should feel the characteristic clicks indicating a proper seal. Ensure the crown is fully screwed down to maintain the watch's water resistance.
