The Rolex Explorer II, a robust and reliable tool watch renowned for its functionality and rugged design, features a crucial complication often overlooked: its independent 24-hour hand and the associated GMT functionality. While not a true GMT watch in the sense of displaying multiple time zones simultaneously on separate hands, the Explorer II's 24-hour hand allows for straightforward tracking of a second time zone, particularly useful for those who frequently travel or work across different geographical locations. This article will delve deep into the intricacies of adjusting the time, date, and importantly, the 24-hour hand, on your Rolex Explorer II, clarifying the process for both novice and experienced owners. We will also address common user queries and dispel some misconceptions surrounding this feature.
Understanding the Explorer II's Timekeeping Mechanism:
Before we jump into the adjustment procedures, it's crucial to understand the watch's mechanism. Unlike a traditional three-hand watch, the Explorer II boasts a fourth hand: the 24-hour hand. This hand completes a full rotation every 24 hours, independent of the hour, minute, and second hands. This allows you to track a second time zone by setting the 24-hour hand to the corresponding time of your reference location. The standard hour hand will show your local time, while the 24-hour hand acts as a reference point for another time zone. This is particularly helpful in differentiating between AM and PM in low-light conditions or when relying solely on the 24-hour hand for a second time zone.
The Explorer II’s movement, typically a self-winding caliber, is highly sophisticated. The accuracy and reliability are a testament to Rolex’s commitment to horological excellence. However, this precision requires careful handling during adjustments. Improper manipulation can lead to damage, so understanding the correct procedures is paramount.
Adjusting the Time and Date:
The adjustment process involves the use of the winding crown, located at the three o'clock position. The crown is a triple-locking system, ensuring water resistance and protecting the delicate internal components. To adjust the time and date, follow these steps:
1. Unscrew the Crown: Carefully unscrew the crown counter-clockwise until it is fully released from its locked position. You will feel distinct clicks as the crown moves.
2. First Click: Date Adjustment: Pulling the crown to the first click allows you to adjust the date. Rotating the crown clockwise will advance the date, while rotating it counter-clockwise will rewind it. It's crucial to only adjust the date between 9 PM and 3 AM to prevent potential damage to the movement. Attempting to adjust the date outside this window might cause complications and could require professional servicing.
3. Second Click: Time Adjustment: Pulling the crown to the second click allows you to adjust the time. Rotating the crown will move both the hour and minute hands. The second hand will usually stop, ensuring accurate time setting. Remember that adjusting the time will also indirectly influence the 24-hour hand.
4. Screw the Crown Back: Once the time and date are correctly set, gently screw the crown back clockwise until it's fully tightened. This secures the crown and maintains the watch's water resistance.
