Setup
Initial Winding
As an automatic watch, the ES-8003-01 is powered by the motion of your wrist. However, for initial setup or if the watch has stopped due to lack of wear, manual winding is recommended.
- Ensure the crown is in its normal, pushed-in position.
- Turn the crown clockwise approximately 20-30 times. This will provide sufficient power reserve to start the watch.
- The second hand should begin to move.
Setting the Time
- Pull the crown out to its outermost position.
- Turn the crown clockwise or counter-clockwise to set the hour and minute hands to the correct time.
- Once the time is set, push the crown back into its normal position.
Operating the Watch
Automatic Movement
The ES-8003-01 features an automatic self-winding movement. This means the watch is powered by the natural motion of your arm while wearing it. When worn daily for approximately 8-10 hours, the watch will maintain its power reserve.
If the watch is not worn for an extended period (typically 36-40 hours, depending on the specific movement's power reserve), it will stop. Simply manually wind it as described in the "Initial Winding" section, or wear it for a few hours to restart the movement.

Water Resistance (5 ATM / 50 Meters)
This watch is water-resistant to 5 ATM (50 meters / 165 feet). This rating means it is suitable for short periods of recreational swimming and showering. It is not suitable for diving, snorkeling, or prolonged water activities.
- Do not operate the crown while the watch is wet or submerged in water.
- Ensure the crown is fully pushed in before any contact with water.
- Avoid exposing the watch to hot water or steam, as this can compromise the water seals.
Maintenance and Care
- Cleaning: Wipe the watch case and crystal with a soft, dry cloth regularly to remove dust and smudges. For the leather strap, avoid excessive moisture and clean with a specialized leather cleaner if necessary.
- Avoid Extreme Temperatures: Do not expose your watch to extreme temperatures (above 60°C / 140°F or below 0°C / 32°F) or sudden temperature changes.
- Magnetic Fields: Keep the watch away from strong magnetic fields (e.g., speakers, refrigerators, mobile phones, airport security scanners), as these can affect the accuracy of the mechanical movement.
- Shocks: While durable, avoid dropping the watch or subjecting it to severe impacts.
- Service: Mechanical watches benefit from periodic servicing (typically every 3-5 years) by a qualified watchmaker to ensure optimal performance and seal integrity.

Troubleshooting
- Watch has stopped:
- Ensure the watch is fully wound. Manually wind the crown 20-30 times.
- Wear the watch for several hours to allow the automatic movement to build power reserve.
- Watch is running inaccurately:
- Check if the watch has been exposed to strong magnetic fields. If so, a professional demagnetization may be required.
- Ensure the watch is fully wound and worn consistently.
- If inaccuracy persists, professional servicing may be needed.
- Condensation under the crystal:
- This indicates a breach in the water resistance. Avoid further water exposure.
- Seek immediate professional service to prevent damage to the movement.
