The Rolex Explorer II, a robust and iconic timepiece synonymous with adventure and exploration, boasts a sophisticated mechanism that requires understanding to operate correctly. This comprehensive guide will walk you through the process of setting the time and date on your Rolex Explorer II, covering everything from winding the movement to utilizing its unique GMT functionality. We’ll also briefly compare the Explorer II with other popular Rolex models to provide context within the broader Rolex family.
Understanding the Rolex Explorer II's Functionality:
Before diving into the setting procedure, it's crucial to understand the Explorer II's key features. Unlike many Rolex models, the Explorer II features a 24-hour hand, independent of the main hour hand, making it ideal for tracking a second time zone. This is a key differentiator, setting it apart from models like the Oyster Perpetual, Air King, and Datejust, which focus primarily on timekeeping in a single time zone. This 24-hour hand, often referred to as the GMT hand, is usually orange for improved visibility.
Step-by-Step Guide: Setting the Time and Date on Your Rolex Explorer II
The crown on your Rolex Explorer II is the key to adjusting all functions. It's a screw-down crown, designed for water resistance, so remember to unscrew it carefully before making any adjustments. The process generally involves three distinct stages:
1. Winding the Movement:
Unscrew the crown by turning it counter-clockwise. Once unscrewed, gently pull the crown out to the first position (approximately 1 click). Now, turn the crown clockwise to wind the mainspring. You should feel a gentle resistance as the mainspring winds. Over-winding isn't detrimental to a modern Rolex movement, but it's unnecessary and can put undue stress on the mechanism. Wind until you feel a slight increase in resistance; this indicates the mainspring is fully wound. Push the crown back in to the fully secured position.
2. Setting the Time:
With the crown unscrewed, pull it out to the second position (approximately 2 clicks). Now you can rotate the crown to adjust the time. Note that moving the hour hand will also move the 24-hour hand proportionally. This ensures that both hands maintain the correct relationship between the two time zones. Carefully set the time according to your preferred time zone. Remember that setting the time between 9 pm and 3 am might interfere with the date change mechanism, so it's best to avoid this period if possible. Once the time is correctly set, push the crown back to the first position.
3. Setting the Date:
With the crown pulled out to the first position (one click), you can now adjust the date. Rotate the crown clockwise to advance the date. It will advance one day at a time. If you need to set a date in the past, rotate the crown counter-clockwise, although it is generally recommended to avoid repeatedly doing this as it can put unnecessary strain on the movement. Once the date is correctly set, push the crown back in to the fully secured position. Ensure the crown is fully screwed down to maintain the watch's water resistance.
