Tools and Materials Needed for Battery Replacement

Before beginning the battery replacement process for your Nixon watch, it is essential to gather the appropriate tools and materials. Using the correct equipment will help avoid damage to the watch case, movement, or seals, ensuring the watch remains functional and water-resistant.

The basic tools and materials required include:

  • A precision screwdriver set, preferably with flat and Phillips heads
  • A case back opener, such as a case knife or a Jaxa wrench for screw-down backs
  • Plastic or non-metal tweezers to handle the battery
  • A new replacement battery compatible with your Nixon model
  • A soft cloth or watch holder to protect the watch during the procedure
  • Optional: A magnifying glass or loupe for detailed inspection

It is also advisable to work in a clean, well-lit environment to prevent dust or debris from entering the watch mechanism.

Tool/Material Description Purpose
Precision Screwdrivers Small flat or Phillips head drivers Remove screws securing the case back or battery holder
Case Back Opener Knife or wrench designed for watch backs Safely open snap or screw-down case backs
Plastic Tweezers Non-metallic tweezers Handle battery without risk of short-circuiting
Replacement Battery Model-specific battery (e.g., SR626SW) Restore power to the watch movement
Soft Cloth/Watch Holder Protective surface Prevent scratches and stabilize watch during repair
Magnifying Glass Optional tool for detail work Enhance visibility of small components

Step-by-Step Battery Replacement Procedure

Once all tools and materials are prepared, follow these carefully outlined steps to replace the battery in your Nixon watch:

Begin by placing the watch face down on the soft cloth or watch holder to avoid scratches to the crystal. Examine the case back to determine whether it is a snap-on or screw-down type.

  • Opening the Case Back:
  • For snap-on backs, gently insert the case knife into the small notch and carefully pry the back open.
  • For screw-down backs, use a Jaxa wrench or adjustable case opener to unscrew the back by aligning the tool’s pins with the grooves on the case back.
  • Removing the Battery:

Locate the battery inside the watch. It is usually held in place by a clip or small screws. Use the precision screwdriver to remove any screws or gently lift the clip with a non-metal tool. Carefully extract the battery using plastic tweezers to avoid short circuits.

  • Identifying Battery Type:

Check the battery number printed on the old battery to ensure you have the correct replacement. Common Nixon watch batteries include models like SR626SW, CR2032, or SR920SW.

  • Installing the New Battery:

Using plastic tweezers, place the new battery into the compartment with the correct polarity—usually positive side facing up. Re-secure any clips or screws that hold the battery.

  • Reassembling the Case Back:

Align the case back properly and press it firmly into place for snap-on backs, ensuring it snaps securely. For screw-down backs, carefully screw the case back on, avoiding cross-threading.

  • Testing the Watch:

Turn the watch over and verify that the second hand is moving or that the digital display is operational. If the watch does not start, double-check the battery installation and contacts for proper placement.

Tips for Maintaining Watch Integrity During Battery Replacement

Maintaining the integrity of your Nixon watch during battery replacement is crucial to preserving its functionality and appearance. Consider the following expert tips:

  • Handle all internal components with care to avoid bending or damaging delicate parts.
  • Avoid touching the battery surface with bare hands; oils and moisture can reduce battery life.
  • Inspect the gasket or rubber seal on the case back for damage or wear. Replace it if necessary to maintain water resistance.
  • Clean the inside of the case back and surrounding areas with a soft brush or cloth to remove dust.
  • Do not force the case back; if it does not close easily, verify alignment and gasket placement.
  • If your watch is water-resistant, consider having a professional perform a pressure test after reassembly.

By adhering to these guidelines, you can ensure the longevity and reliability of your Nixon watch after battery replacement.

Identifying the Battery Type for Your Nixon Watch

Determining the correct battery type is essential before starting the replacement process. Nixon watches use various battery models depending on the specific watch design and features.

To identify the correct battery:

  • Check the user manual that came with your Nixon watch; it typically lists the battery type.
  • Look for the battery model number engraved on the back case or inside the watch once opened.
  • Consult Nixon’s official website or customer service with your watch model number for accurate battery specifications.
Common Nixon Watch Models Typical Battery Type Battery Model Number
Nixon Time Teller Silver Oxide SR621SW (364)
Nixon Sentry Silver Oxide SR920SW (370)
Nixon 51-30 Chrono Silver Oxide SR927SW (395)

Using the correct battery type ensures optimal performance and avoids damage to the watch’s movement.

Tools Required for Battery Replacement

Before proceeding, assemble all necessary tools to facilitate a smooth and safe battery change:

  • Watch case opener (case knife or case wrench depending on back type)
  • Plastic or non-metallic tweezers to handle the battery
  • Small precision screwdriver set (for screw-down back cases)
  • Soft cloth or watch holder to protect the watch face
  • Replacement battery matching the original model
  • Magnifying glass or loupe (optional, for better visibility)

Using metal tools carelessly can damage internal components, so select appropriate non-scratching instruments when possible.

Step-by-Step Procedure to Replace the Battery

Follow these detailed steps to change the battery in your Nixon watch safely and efficiently:

  1. Prepare your workspace: Place the watch face down on a soft cloth to prevent scratches.
  2. Open the watch case:
    • If your watch has a snap-back case, use a case knife to gently pry it open at the designated notch.
    • If it has a screw-down case back, use a case wrench or appropriate screwdriver to unscrew it.
  3. Locate the battery: Identify the battery inside the watch. It is usually held in place by a clip or small screw.
  4. Remove the battery:
    • If secured by a clip, gently lift the clip or unscrew it using a precision screwdriver.
    • Use plastic tweezers to carefully extract the battery to avoid short circuits or damage.
  5. Insert the new battery:
    • Position the new battery with the correct polarity (usually positive side up).
    • Secure the battery under the clip or screw it back in place if applicable.
  6. Close the watch case:
    • For snap-back cases, align the case back carefully and press firmly until it snaps shut.
    • For screw-down cases, align threads and tighten using the case wrench or screwdriver.
  7. Test the watch: Turn the watch face over and verify that it is running correctly.

If the watch does not start immediately, double-check battery placement and polarity, or consult a professional watch technician.

Precautions and Tips for Battery Replacement

Handling watch batteries and delicate components requires attention to detail and care. Consider the following precautions:

  • Avoid touching the new battery with bare hands to prevent oils and dirt transfer; use tweezers or gloves.
  • Never force the case back open or closed; doing so can damage the watch or its water resistance.
  • Maintain a clean and dust-free environment to prevent debris from entering the watch.
  • Note the orientation and position of the battery before removal to ensure correct reinstallation.
  • If your watch is water-resistant, verify that the case back gasket is intact and properly seated before closing to maintain water resistance.
  • Dispose of old batteries according to local hazardous waste regulations.

When to Seek Professional Assistance

While battery replacement can often be performed at home, certain conditions warrant expert intervention:

  • The watch has a complex or sealed case that requires specialized tools.
  • There are signs of corrosion
