Rolex Explorer II Automatic Chronometer

Product Overview

The Rolex Explorer II is a robust and reliable timepiece designed for adventurers and explorers. Known for its distinctive 24-hour hand and fixed bezel, it allows for the simultaneous tracking of a second time zone or distinguishing between day and night hours. This automatic chronometer is a testament to Rolex's precision engineering and enduring design.

This image displays the Rolex Explorer II, model 226570BKSO, featuring a striking black dial with luminous hour markers and hands. The distinctive orange 24-hour hand is prominent, indicating the GMT function. The watch is encased in brushed stainless steel, complemented by a matching Oyster bracelet and a fixed 24-hour engraved bezel.

Setup and Initial Operation

1. Unscrewing the Winding Crown: To access the winding and setting functions, gently unscrew the winding crown counter-clockwise until it springs free from the case.
2. Manual Winding: If the watch has stopped or its power reserve is low, wind it manually by turning the crown clockwise approximately 25 times. This will build up sufficient power reserve for the watch to function.
3. Setting the Time: Pull the crown out to the third position. Turn the crown in either direction to set the hour and minute hands. The independent 24-hour hand will also move.
4. Setting the Date: Pull the crown out to the second position. Turn the crown clockwise to advance the date. The date changes instantaneously at midnight.
5. Setting the 24-Hour Hand (GMT Function): The 24-hour hand is linked to the main hour hand. To set a second time zone, first set the local time using the hour and minute hands. Then, use the fixed 24-hour bezel to read the second time zone by aligning the 24-hour hand with the desired hour on the bezel.
6. Screwing Down the Winding Crown: Once all settings are complete, push the crown back in and screw it down clockwise firmly against the case. This ensures the watch's water resistance.

Operating the Watch

• Automatic Winding: The Explorer II is equipped with a Perpetual rotor, an automatic winding mechanism that winds the watch using the natural movements of your wrist. When worn regularly, it does not require manual winding.
• Water Resistance: The Rolex Explorer II is water-resistant to 100 meters (330 feet). Ensure the winding crown is always screwed down tightly before any contact with water to maintain its water resistance. It is suitable for swimming and snorkeling, but not for scuba diving.
• Chronometer Certification: This watch is a Superlative Chronometer, officially certified by COSC (Contrôle Officiel Suisse des Chronomètres) and re-tested by Rolex after casing to ensure exceptional precision (-2/+2 seconds per day).

Maintenance and Care

• Cleaning: To preserve the watch's luster, clean it regularly with a soft cloth. For more thorough cleaning, use soapy water and a soft brush, then rinse with clear water and dry with a soft cloth. Ensure the crown is screwed down before cleaning with water.
• Service Intervals: Rolex recommends having your watch serviced approximately every 10 years to ensure optimal performance and longevity. Only authorized Rolex service centers should perform maintenance.
• Avoid Extreme Conditions: While robust, avoid exposing your watch to extreme temperatures, strong magnetic fields, or harsh chemicals.
• Storage: When not wearing your watch, store it in a cool, dry place, preferably in its original box or a watch winder to maintain its power reserve.
