Setup
Setting the Time and Date:
- Pull out the crown to position 2 (first click) to set the date. Turn the crown clockwise or counter-clockwise until the correct date is displayed.
- Pull out the crown to position 3 (second click) to set the time. Turn the crown to move the hour and minute hands. To ensure accurate time setting, align the minute hand with the correct minute mark after the second hand reaches the 12 o'clock position.
- Push the crown back to position 1 (normal position) to start the watch.
Note: Avoid setting the date between 9:00 PM and 3:00 AM, as this may damage the date mechanism. If the date needs to be adjusted during this period, first set the time outside this window, adjust the date, and then reset the time.
Operating Instructions
Using the Chronograph Function:
Your ES-8270 features a precise chronograph for measuring elapsed time.
- Starting the Chronograph: Press pusher A (top pusher) to start the chronograph. The large central second hand will begin to move, and the chronograph minute sub-dial will track elapsed minutes.
- Stopping the Chronograph: Press pusher A again to stop the chronograph. The hands will freeze, showing the elapsed time.
- Resetting the Chronograph: After stopping, press pusher B (bottom pusher) to reset all chronograph hands to their zero positions.
- Split Time (if applicable): Some chronographs allow for split time measurement. Consult the specific movement details if this feature is desired. For this model, the primary function is start/stop/reset.
Note: Do not operate the chronograph pushers while the watch is wet or submerged in water.
Maintenance
Care and Longevity:
- Cleaning: Wipe the watch case and strap regularly with a soft, dry cloth. For the leather strap, avoid excessive moisture.
- Water Resistance: While your watch may have some water resistance, it is generally recommended to avoid prolonged exposure to water, especially hot water, steam, or chemical substances. Do not operate the crown or pushers when the watch is wet.
- Temperature Extremes: Avoid exposing your watch to extreme temperatures (hot or cold) or sudden temperature changes, as this can affect the movement and battery life.
- Magnetic Fields: Keep your watch away from strong magnetic fields (e.g., speakers, refrigerators, mobile phones), which can affect the accuracy of the quartz movement.
- Battery Replacement: The quartz movement is powered by a battery. When the battery runs low, the second hand may start to jump every few seconds (End-of-Life indicator). Have the battery replaced by a qualified watchmaker to ensure proper sealing and function.
- Strap Care: Genuine leather straps can wear over time. Avoid prolonged exposure to direct sunlight, water, and harsh chemicals to preserve their quality.
Troubleshooting
If you encounter any issues with your watch, please refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Watch stops or runs intermittently. | Low battery. | Replace the battery. |
| Time is inaccurate. | Exposure to strong magnetic fields; incorrect time setting. | Demagnetize the watch (by a professional); reset the time correctly. |
| Date does not change or changes at wrong time. | Incorrect date setting; date set during prohibited hours. | Reset the date outside of 9 PM - 3 AM. |
| Chronograph hands do not reset to zero. | Requires calibration. | Consult a professional watchmaker for adjustment. |
