However, with the right approach and tools, it’s a manageable task that many watch enthusiasts undertake at home. Understanding the basics of your watch’s construction and the proper steps involved will ensure you don’t risk damaging this valuable piece.

Before diving into the process, it’s important to appreciate the nuances that make Invicta watches unique and to prepare adequately for the battery replacement. This article will guide you through the essentials, helping you gain confidence and knowledge to keep your Invicta watch running perfectly for years to come.

Opening the Watch Case

To access the battery compartment of an Invicta watch, you first need to carefully open the watch case. Invicta watches generally feature one of two types of case backs: screw-down or snap-off. Identifying the type will help you determine the appropriate method and tools for opening the case.

For screw-down case backs, you will require a specialized case back wrench or a suitable adjustable tool that fits the notches on the case back. Align the wrench with the notches and turn counterclockwise gently but firmly to unscrew the back. For snap-off case backs, a thin, flat tool such as a case knife or a small flathead screwdriver is necessary. Insert the tool carefully into the small gap between the case back and the watch body, then gently pry it open without applying excessive force to avoid damaging the case or the gasket.

When opening the watch case, follow these precautions:

  • Work on a clean, flat surface with adequate lighting.
  • Use a soft cloth or mat to prevent scratches on the watch.
  • Avoid touching internal components with bare fingers to prevent oils from contaminating the movement.
  • Keep all removed parts in a safe place to avoid loss.

Removing and Identifying the Battery

Once the case back is removed, the battery will be visible, usually held in place by a small clip or metal retainer. Before proceeding, note the battery’s size and type, as this information is crucial for purchasing the correct replacement.

To remove the battery:

  • Use plastic tweezers or a non-metallic tool to avoid short-circuiting or damaging the watch movement.
  • Carefully release the clip or retainer holding the battery. Some models may have small screws securing the retainer; if so, use a precision screwdriver to remove them.
  • Lift the battery out gently and avoid touching it with bare hands to prevent corrosion or contamination.

The battery type is often printed on the battery itself, typically a standard silver oxide button cell. The most common types used in Invicta watches include SR626SW, SR621SW, or SR920SW, but it is essential to verify the exact model.

Below is a table of common Invicta watch battery sizes and their equivalents:

Battery Code Common Name Voltage Diameter (mm) Height (mm)
SR626SW 377 1.55V 6.8 2.6

  • Listen for a click or feel the case snap securely into place.

For screw-down case backs:

  • Place the case back on the watch body, aligning the notches.
  • Using the case back wrench, turn clockwise to screw the back on securely.
  • Avoid excessive force to prevent stripping the threads.

Additional tips:

  • Inspect the gasket or rubber seal for damage or dirt before closing. Replace it if necessary to ensure water resistance.
  • If the gasket is intact but dry, apply a small amount of silicone grease to maintain flexibility and sealing.

Testing the Watch After Battery Replacement

Once the case is closed, test the watch to confirm the battery replacement was successful and the watch is functioning correctly.

Key checks include:

  • Verifying that the second hand is moving smoothly.
  • Checking the date and other complications for proper operation.
  • Ensuring the crown and pushers respond correctly.
  • Confirming that the watch maintains time over the next 24 hours.

If the watch does not start after battery installation, recheck the battery orientation and contacts. In some cases, a gentle tap or resetting the watch might be necessary.

By following these detailed steps, you can effectively change the battery in your Invicta watch while preserving its functionality and longevity.
