3. Setup
3.1 Setting the Time and Date

- Pull the crown out to position 3 (second click). The second hand will stop.
- Rotate the crown to set the local hour and minute hands. Ensure the AM/PM is correctly set if your watch has a 24-hour indicator or date change mechanism.
- Push the crown back to position 1 (normal operating position) to start the watch.
3.2 Setting the GMT (Second Time Zone)
The GMT hand typically operates on a 24-hour scale.
- Pull the crown out to position 2.
- Rotate the crown in the appropriate direction to move the GMT hand to the desired second time zone. The GMT hand usually makes one full rotation in 24 hours.
- Once the GMT hand is set, push the crown back to position 1.
Note: Specific crown functions may vary slightly. If you encounter difficulty, consult a qualified watchmaker or RAYMOND WEIL customer support.
4. Operating Instructions
4.1 Timekeeping
Once the time and date are set, your quartz watch will operate continuously. The second hand will move in distinct steps.
4.2 Reading GMT Time
The GMT hand, often distinguished by color or shape, points to a 24-hour scale on the dial or bezel, indicating the time in your chosen second time zone. For example, if the GMT hand points to '18' on the 24-hour scale, the time in the second zone is 6 PM.
5. Maintenance
5.1 Cleaning
To maintain the appearance of your watch, wipe the case and bracelet regularly with a soft, dry cloth. For stainless steel, a slightly damp cloth can be used, followed by immediate drying. Avoid using harsh chemicals or abrasive materials.
5.2 Water Resistance (30 ATM)
Your watch is water-resistant to 30 ATM (300 meters / 1000 feet). This rating makes it suitable for professional marine activity, serious surface water sports, and skin diving.
- Always ensure the crown is fully pushed in before any contact with water.
- Do not operate the crown or pushers while the watch is wet or submerged.
- After exposure to saltwater, rinse the watch with fresh water and dry it thoroughly.
- Water resistance is not a permanent characteristic and may decrease over time due to aging of gaskets or accidental shocks. It is recommended to have the water resistance checked annually by an authorized service center.
5.3 Battery Replacement
As a quartz watch, it is powered by a battery. The typical battery life is 2-3 years. When the battery is low, the second hand may start to jump in 2 or 4-second intervals (End-of-Life indicator). It is recommended to have the battery replaced by an authorized RAYMOND WEIL service center to ensure proper sealing and function.
5.4 Storage
When not wearing your watch, store it in a cool, dry place, away from direct sunlight, extreme temperatures, and strong magnetic fields.
