1. Introduction
The GLENAW Automatic Watch Model 8668 is a self-winding mechanical timepiece designed for men. It features a distinctive dial with a golden sailboat motif, a day and date calendar display, and a durable stainless steel strap. This watch is built for daily wear with 30m water resistance.

2. Initial Setup and Winding
Your GLENAW automatic watch operates without a battery, relying on the natural motion of your wrist to power its self-winding mechanism. For the first use, or if the watch has stopped due to inactivity, manual winding is required to initiate the movement and ensure accurate timekeeping.
Manual Winding Procedure:
- Ensure the crown is in its fully pushed-in position (position 0).
- Rotate the crown clockwise approximately 30-40 times. This will build up sufficient power reserve to start the watch.
- Once manually wound, the watch will begin to operate. Subsequent daily wear will maintain the power reserve through the automatic self-winding feature.
Note: Insufficient manual winding or prolonged periods of inactivity may cause the watch to stop. Regular wear or manual winding will prevent this.

3. Operating Your Watch
Setting Time and Date:
To adjust the time and date, pull the crown out to the appropriate position. Refer to the diagram below for crown positions.

- Position 0 (Pushed In): Normal operating position.
- Position 1 (Pulled Out One Click): Rotate to adjust the date.
- Position 2 (Pulled Out Two Clicks): Rotate to adjust the time.
After setting, push the crown back to Position 0 to ensure water resistance and proper operation.
Water Resistance:
This watch features 3ATM (30 meters) water resistance. This means it can withstand daily splashes, hand washing, and sweat. It is not suitable for swimming, diving, or use in hot water environments (e.g., showers, saunas), as steam and temperature changes can compromise the seals.

4. Care and Maintenance
- Cleaning: Wipe the watch regularly with a soft, dry cloth to remove dust and smudges. For the stainless steel strap, a slightly damp cloth can be used, followed by immediate drying.
- Avoid Chemicals: Do not expose the watch to harsh chemicals, solvents, or detergents, as these can damage the case, strap, or seals.
- Temperature Extremes: Avoid sudden temperature changes or extreme temperatures, which can affect the watch's accuracy and longevity.
- Magnetic Fields: Keep the watch away from strong magnetic fields (e.g., speakers, refrigerators, certain electronic devices), as magnetism can interfere with the mechanical movement.
- Impact: Protect the watch from strong impacts or drops.
5. Troubleshooting
Watch Stops or Loses Time:
As a mechanical watch, it requires sufficient kinetic energy to operate. If the watch stops or shows significant time deviation, it is likely due to insufficient power reserve.
- Solution: Manually wind the watch by rotating the crown clockwise 30-40 times. Wear the watch regularly for at least 8-10 hours a day to allow the automatic winding mechanism to maintain the power reserve.
- Note: Mechanical watches are inherently different from quartz watches and may have slight daily variations in timekeeping.
