The Rolex Explorer II, a robust and reliable tool watch, boasts a unique date-changing mechanism. Unlike many other watches where the date advances by simply turning the crown, the Explorer II's date adjustment is linked to the movement of the hour hand. This article will detail precisely how to change the date on your Rolex Explorer II, along with addressing common questions and comparing it to other Rolex models.
Changing the Date on Your Rolex Explorer II:
The key to changing the date on a Rolex Explorer II lies in understanding its quickset mechanism. This mechanism is designed to prevent accidental date changes and protects the delicate internal components. You cannot directly adjust the date via the crown. Instead, the date advances when the hour hand passes the midnight position (12 o'clock). To change the date, follow these steps:
1. Unscrew and pull the crown to position 3: This activates the hour hand adjustment. The crown positions are as follows:
* Position 1 (fully screwed in): Normal operation, crown is protected.
* Position 2 (partially pulled): Allows for winding the watch's mainspring.
* Position 3 (fully pulled): Allows adjustment of the hour hand.
2. Move the hour hand: Slowly turn the crown, moving the hour hand forward in one-hour increments. Do *not* attempt to rapidly spin the crown; this can damage the movement. This is crucial, as directly manipulating the date wheel is not possible.
3. Cross the midnight mark: Continue moving the hour hand until it passes the 12 o'clock position. This is the crucial step. As the hour hand crosses midnight, the date will automatically advance to the next day.
4. Set the correct time: Once the date has changed, continue adjusting the hour hand to set the precise time. Remember to adjust the minute hand accordingly using the same crown in position 3.
5. Screw the crown back in: Once the time is correctly set, carefully screw the crown back into position 1 to protect the movement from dust and water.
Important Considerations:
* Never attempt to change the date between 9 PM and 3 AM: This is the period when the date mechanism is engaged, and trying to force a date change during this time can damage the movement. It's always best to change the date in the morning or early afternoon.
* Gentle movements: Always use gentle, controlled movements when adjusting the hands. Avoid jerky or forceful actions.
* 24-hour hand: The Explorer II features a 24-hour hand, crucial for its purpose as a tool watch. Ensure this hand is correctly set alongside the standard hour hand. The 24-hour hand should always correspond to the hour hand's position, reflecting the current time in a 24-hour format.
* If the date doesn't change: If you've followed these steps and the date hasn't changed, it's likely a problem with the movement. Consult a qualified watchmaker or Rolex authorized service center for repair.
