Setup
1. Initial Inspection
Upon unboxing, carefully inspect your watch for any visible damage. Ensure all protective films are removed from the crystal and case back.
2. Setting the Time
- Pull the crown out to the second click position (position 2). The second hand will stop.
- Turn the crown to set the hour and minute hands to the desired time.
- Push the crown back to the normal position (position 0). The second hand will resume movement.
3. Setting the Date
- Pull the crown out to the first click position (position 1).
- Turn the crown clockwise or counter-clockwise to set the date. Avoid setting the date between 9 PM and 3 AM, as this may interfere with the automatic date change mechanism.
- Push the crown back to the normal position (position 0).
4. Chronograph Hand Reset
If the chronograph hands (stopwatch hands) do not reset to the zero position after use, they may need calibration. Refer to the "Troubleshooting" section for adjustment instructions.
5. Band Adjustment
The stainless steel band can be adjusted by adding or removing links. This procedure typically requires specialized tools and is best performed by a qualified watchmaker or jeweler to prevent damage to the band or clasp.
Operating Instructions
1. Basic Timekeeping
Your watch continuously displays the current time (hours, minutes, seconds) and date once properly set. The Swiss Quartz movement ensures accurate timekeeping.
2. Chronograph Functions
The chronograph feature allows you to measure elapsed time. It typically operates using two pushers located on either side of the crown.
- Start: Press the upper pusher (A) to start the chronograph. The chronograph second hand will begin to move.
- Stop: Press the upper pusher (A) again to stop the chronograph. The elapsed time will be displayed by the chronograph hands.
- Reset: While the chronograph is stopped, press the lower pusher (B) to reset all chronograph hands to their zero positions.
3. Water Resistance
This watch is water resistant to 330 feet (100 meters). This rating makes it suitable for snorkeling and swimming. It is not suitable for diving. Ensure the crown is fully pushed in before any contact with water. Do not operate the pushers or crown while the watch is wet or submerged, as this can compromise the water resistance.
Maintenance
1. Cleaning
To maintain the appearance of your watch, wipe the case and band regularly with a soft, dry cloth. For stainless steel bands, a slightly damp cloth can be used, followed by immediate drying. Avoid using chemical cleaners or abrasive materials.
2. Battery Replacement
Your quartz watch is powered by a battery. When the battery is depleted, the watch will stop running. Battery replacement should be performed by a qualified watch technician to ensure the proper sealing and water resistance are maintained.
3. Storage
When not wearing your watch, store it in a cool, dry place away from direct sunlight, extreme temperatures, and strong magnetic fields. The original watch box is ideal for storage.
4. Water Resistance Checks
Over time, the gaskets that ensure water resistance can degrade. It is recommended to have your watch's water resistance checked by a professional watchmaker every 2-3 years, especially if it is frequently exposed to water.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Watch not running | Depleted battery | Replace battery (professional service recommended). |
| Date not changing at midnight | Time set incorrectly (AM/PM) | Advance the time by 12 hours. |
| Chronograph hands do not reset to zero | Misalignment |
|
| Condensation under crystal | Water ingress, compromised water resistance | Immediately take the watch to a professional watchmaker for inspection and repair to prevent further damage. |
