2. Setup Instructions
2.1 Winding the Automatic Movement
Your Invicta 3826 watch is equipped with an automatic mechanical movement. It does not require a battery. The watch is powered by the natural motion of your wrist. To initiate power if the watch has stopped:
- Gently shake the watch from side to side for approximately 30 seconds to start the movement.
- Alternatively, manually wind the watch by rotating the crown clockwise while it is in its normal, pushed-in position (position 0). Wind approximately 20-30 turns until the second hand begins to move smoothly.
Regular wear will keep the watch sufficiently wound. If worn daily for 8-12 hours, manual winding should not be necessary.
2.2 Setting Time and Date
To set the time and date on your watch:
- Pull the crown out to Position 2 (farthest out). This stops the second hand. Rotate the crown to set the hour and minute hands. Ensure the AM/PM is correctly set by advancing the hands past 12 o'clock to see if the date changes.
- Push the crown in to Position 1 (middle position). Rotate the crown to set the date. Turn the crown until the correct date appears in the date window. Avoid setting the date between 9 PM and 3 AM, as this can damage the movement.
- Push the crown back in to Position 0 (normal position). Ensure the crown is fully pushed in to maintain water resistance.
3. Operating Your Watch
3.1 Wearing the Watch
Fasten the watch securely but comfortably on your wrist using the deployment clasp with safety. The automatic movement relies on your wrist's motion, so consistent wear is recommended for optimal performance.
3.2 Water Resistance
This watch is water resistant to 200 meters (660 feet). This rating makes it suitable for recreational scuba diving. However, always ensure the crown is fully pushed in before exposing the watch to water. Do not operate the crown or pushers (if any) while the watch is submerged or wet, as this can compromise the water seal.
4. Care and Maintenance
4.1 Cleaning
To maintain the appearance of your gold-plated stainless steel watch:
- Wipe the case and band with a soft, damp cloth.
- For stubborn dirt, use a mild soap solution and a soft brush, then rinse thoroughly with clean water and dry immediately with a soft cloth.
- Avoid harsh chemicals, abrasive cleaners, or solvents, as these can damage the gold plating and seals.
4.2 Sapphire Crystal Care
The sapphire crystal is highly scratch-resistant. Clean it with a soft, lint-free cloth. While durable, it is not entirely shatterproof; avoid severe impacts.
4.3 Storage
When not wearing the watch, store it in a cool, dry place away from direct sunlight and strong magnetic fields, which can affect the accuracy of the automatic movement.
5. Troubleshooting
5.1 Watch Not Running or Losing Time
- Insufficient Winding: Ensure the watch is adequately wound either by wearing it consistently or by manually winding it (refer to Section 2.1).
- Lack of Movement: If the watch is not worn for an extended period, the power reserve will deplete. Re-wind as per Section 2.1.
- Magnetic Fields: Exposure to strong magnetic fields can affect accuracy. If suspected, consult a professional watchmaker for demagnetization.
5.2 Date Not Changing Correctly
- Incorrect Time Setting: Ensure the time is set correctly, especially the AM/PM cycle, as the date changes around midnight.
- Date Setting Restriction: Avoid setting the date manually between 9 PM and 3 AM. If the date needs adjustment during this period, first set the time outside this window, adjust the date, then reset the time.
5.3 Water Intrusion
If moisture or condensation appears inside the watch crystal, immediately take the watch to a qualified service center. This indicates a compromised water seal, and prompt action is necessary to prevent further damage to the movement.
