3. Watch Components

Familiarize yourself with the main parts of your BERNY automatic watch:

• Crown: Located on the right side of the watch case, used for winding and setting time/date.
• Dial: The watch face displaying time, day, date, and other indicators.
• Hands: Hour, minute, and second hands for time indication.
• Date Window: Displays the current date, typically at the 12 o'clock position.
• Day Sub-dial: Displays the current day of the week, typically on the left side of the dial.
• 24-Hour Sub-dial: Displays time in a 24-hour format, typically on the right side of the dial.
• Open-Heart Skeleton: A window on the dial revealing parts of the mechanical movement.
• Case: The main body of the watch, made of stainless steel.
• Strap/Bracelet: Secures the watch to your wrist (leather for AM042M, stainless steel for AM052M).
• Clasp/Buckle: Mechanism to fasten the strap/bracelet.
• Case Back: The rear cover of the watch, often transparent to showcase the movement.

4. Initial Setup

Before wearing your watch for the first time, or after it has stopped due to lack of power, follow these steps:

1. Manual Winding: Your watch is an automatic mechanical timepiece. If it has stopped, manually wind it by rotating the crown clockwise approximately 30-40 times while it is in its normal (pushed-in) position. This builds up a power reserve.
2. Setting the Time:
   • Pull the crown out to the furthest position (Position 3).
   • Rotate the crown to move the hands clockwise or counter-clockwise until the desired time is set.
   • Push the crown back into its normal position (Position 1).
3. Setting the Date and Day:
   • Pull the crown out to the middle position (Position 2).
   • Rotate the crown clockwise to adjust the date.
   • Rotate the crown counter-clockwise to adjust the day of the week.
   • Important: Avoid setting the date or day between 9 PM and 3 AM, as this is when the watch's internal date change mechanism is engaged and could be damaged. If you need to set the date/day during this period, first set the time outside this window (e.g., to 6 AM), then adjust the date/day, and finally set the correct time.
   • Once set, push the crown back into its normal position (Position 1).
4. Wearing the Watch: Adjust the strap/bracelet to fit comfortably on your wrist. The automatic movement will then continue to wind itself through your natural arm movements.

5. Operation

Automatic Movement

Your BERNY watch is powered by an automatic mechanical movement. This means it is wound by the motion of your wrist. When worn regularly (8-10 hours a day), it should maintain its power reserve. If the watch is not worn for an extended period, it will stop and require manual winding as described in the 'Initial Setup' section.

Day and Date Display

The watch features a day display (typically a sub-dial on the left) and a date window (typically at 12 o'clock). These indicators advance automatically once every 24 hours. The 24-hour sub-dial on the right tracks the current time in a 24-hour format, synchronizing with the main hour hand.

Water Resistance (5ATM)

Your watch has a water resistance rating of 5ATM (50 meters). This means it is suitable for daily use, such as accidental splashes, rain, and showering. It is NOT suitable for swimming, diving, or prolonged water immersion. Always ensure the crown is fully pushed in before any contact with water.

6. Maintenance

Proper care will help preserve the appearance and functionality of your BERNY watch:

• Cleaning: Wipe the watch case and crystal with a soft, dry cloth regularly. For leather straps, avoid excessive moisture and harsh chemicals. For stainless steel bracelets, a soft brush with mild soap and water can be used, followed by thorough drying.
• Avoid Extreme Conditions: Protect your watch from extreme temperatures, direct sunlight for prolonged periods, and strong magnetic fields, which can affect accuracy.
• Water Resistance Precautions: Do not operate the crown or pushers (if present) when the watch is wet or submerged in water. Always ensure the crown is fully pushed in.
• Storage: When not wearing the watch, store it in a cool, dry place, preferably in its original box or a watch case to protect it from dust and scratches.
• Servicing: Mechanical watches benefit from periodic professional servicing (typically every 3-5 years) to clean, lubricate, and adjust the movement, ensuring optimal performance and longevity.

7. Troubleshooting

Here are solutions to common issues you might encounter:

• Watch Not Running:
  • Cause: Insufficient power reserve.
  • Solution: Manually wind the watch by rotating the crown clockwise 30-40 times. Wear the watch regularly to allow the automatic movement to self-wind.
• Date/Day Not Changing or Changing Incorrectly:
  • Cause: Incorrect setting, or setting during the forbidden time (9 PM - 3 AM).
  • Solution: Reset the date and day as per the 'Setting the Date and Day' instructions, ensuring you avoid the forbidden time window. If the issue persists, consult a professional watchmaker.
• Inaccurate Timekeeping:
  • Cause: Mechanical watches are not as precise as quartz watches. Exposure to magnetic fields or physical shocks can also affect accuracy.
  • Solution: If the watch is consistently fast or slow by more than +/- 30 seconds per day, it may require adjustment by a professional watchmaker. Demagnetization may be needed if exposed to strong magnetic fields.
• Moisture Inside the Watch:
  • Cause: Crown not fully pushed in, exceeding water resistance limits, or seal degradation.
  • Solution: Immediately take the watch to a professional watchmaker to prevent further damage to the movement. Do not attempt to dry it yourself.

8. User Tips

• Understanding Sub-dials: The sub-dial on the right side of the watch displays time in a 24-hour format, not a monthly indicator. It moves in sync with the main hour hand to show whether it's AM or PM in a 24-hour cycle. The date window at 12 o'clock changes daily.
• Consistent Wear: For optimal performance of the automatic movement, wear your watch consistently. If you rotate watches, consider a watch winder to keep it running and accurate.
• Gentle Handling: While durable, mechanical watches contain intricate parts. Avoid dropping the watch or subjecting it to severe impacts.

9. Warranty and Support

BERNY watches typically come with a limited manufacturer's warranty covering defects in materials and workmanship. Please refer to the warranty card included with your purchase for specific terms and conditions, including the warranty period and coverage details.

For technical support, repairs, or warranty claims, please contact the authorized BERNY service center or the retailer from whom you purchased the watch. Ensure you retain your proof of purchase for any warranty services.
