The Rolex Submariner, a legendary dive watch synonymous with rugged durability and precision timekeeping, demands a certain level of understanding regarding its operation. While its robust construction speaks to its ability to withstand extreme underwater pressures, its functionality relies on a careful and precise approach to setting the time and utilizing its unique features. This comprehensive guide will walk you through the process of setting the time on your Rolex Submariner, clarifying potential points of confusion and highlighting important safety considerations. We'll also delve into the Submariner's unique unidirectional bezel and its role in dive timing.
Understanding the Rolex Submariner Mechanism:
Before we delve into the specifics of setting the time, it's crucial to understand the underlying mechanics of the Rolex Submariner. Most modern Submariners are equipped with a self-winding (automatic) movement, meaning they are powered by the natural movement of your wrist. This eliminates the need for manual winding in most cases, although manual winding is possible and sometimes recommended to ensure a full power reserve. The movement is housed within a robust Oyster case, renowned for its water resistance. The crown, located at 3 o'clock, is the key to setting the time and date.
Setting the Time:
1. Unscrew the Crown: The Submariner's crown is screw-down, designed to ensure water resistance. To set the time, carefully unscrew the crown by turning it counter-clockwise. You should feel distinct clicks as it unscrews. Typically, you'll need to turn it around a quarter to half a turn, depending on the model. Don't force it; if it feels resistant, stop and check your technique.
2. Pull Out the Crown: Once the crown is unscrewed, pull it out to the first position (one click). In this position, you can now adjust the time. Turning the crown clockwise will move the hands forward, and turning it counter-clockwise will move them backward.
3. Setting the Time: Carefully adjust the time until it matches your desired time. Take your time and ensure accuracy. Remember, the minute hand moves in one-minute increments.
4. Push In the Crown: Once the time is correctly set, gently push the crown back into its fully screwed position. Ensure that you feel the crown securely engage and screw tightly. This is crucial for maintaining the watch's water resistance. Any gaps can allow water to seep in, damaging the movement.
Setting the Date (If Applicable):
Many Rolex Submariners feature a date complication. To set the date, after pulling the crown out to the first position (as described above for setting the time), continue pulling the crown out to the second position (a second click). In this position, turning the crown will adjust the date. It's important to note that adjusting the date between 9 PM and 3 AM is generally not recommended, as this is when the date mechanism is active. Attempting to change the date during this period may damage the movement.
The Unidirectional Bezel: Its Role and Significance:
The Submariner's distinctive unidirectional rotating bezel is a crucial element for divers. It allows divers to track their elapsed dive time. The bezel rotates only in one direction (counter-clockwise), preventing accidental underestimation of dive time – a critical safety feature.
