3. Setup and Installation

Installing a watch movement requires precision and a clean working environment. It is highly recommended that this procedure be performed by a qualified watchmaker or experienced technician.

Preparation:

• Ensure your workspace is clean, dust-free, and well-lit.
• Use appropriate watchmaking tools, including movement holders, tweezers, and screwdrivers.
• Wear finger cots or gloves to prevent oils and debris from contaminating the movement.
• Handle the movement by its edges or the movement holder to avoid touching delicate components.

Installation Steps (General Guidance):

1. Carefully remove the old movement from the watch case, if applicable.
2. Inspect the new WNSC 2813 movement for any visible defects or debris.
3. Attach the dial and hands to the movement, ensuring proper alignment and clearance.
4. Insert the winding stem into the movement and secure it.
5. Place the assembled movement into the watch case, ensuring it sits securely.
6. Secure the movement with movement screws or clamps, if present in the case design.
7. Re-attach the case back, ensuring a proper seal.

Note: Specific installation steps may vary depending on the watch case design. Consult a professional if unsure.

4. Operating the Movement

The 2813 is an automatic mechanical movement, meaning it winds itself through the motion of the wearer's wrist. It also supports manual winding and features a date complication.

Winding the Movement:

• Automatic Winding: The rotor on the back of the movement rotates with wrist movement, winding the mainspring. For initial start-up or after a period of inactivity, wear the watch for several hours.
• Manual Winding: With the crown in the normal (pushed-in) position, turn it clockwise approximately 20-30 times to manually wind the mainspring. Do not overwind.

Setting Time and Date:

1. Setting the Date: Pull the crown out to the first click position. Turn the crown counter-clockwise to adjust the date. Avoid setting the date between 9 PM and 3 AM, as this is when the date change mechanism is engaged and could be damaged.
2. Setting the Time: Pull the crown out to the second click position. Turn the crown in either direction to set the time. Push the crown back in to the normal position to start the movement.

5. Maintenance and Care

Proper maintenance ensures the longevity and accuracy of your 2813 automatic movement.

• Regular Servicing: Mechanical movements require periodic servicing (typically every 3-5 years) by a professional watchmaker. This involves cleaning, lubricating, and regulating the movement.
• Avoid Shocks: While durable, mechanical movements are sensitive to strong impacts. Avoid dropping the watch or exposing it to severe shocks.
• Temperature Extremes: Protect the movement from extreme temperatures, both hot and cold, as they can affect lubrication and accuracy.
• Magnetic Fields: Keep the watch away from strong magnetic fields (e.g., speakers, refrigerators, certain electronic devices) as magnetism can affect the movement's accuracy. If magnetized, demagnetization by a professional may be required.
• Cleanliness: Ensure the watch case is properly sealed to prevent dust and moisture from entering the movement.

6. Troubleshooting

If you encounter issues with your 2813 movement, consider the following common problems and solutions:

For complex issues or if the above solutions do not resolve the problem, it is strongly advised to consult a professional watch repair technician.
