Tools and Materials Needed for Battery Replacement

Before beginning the process of replacing a Guess watch battery, it is essential to gather the proper tools and materials. Using the correct equipment ensures the watch remains undamaged and the replacement is successful.

Common tools required include:

  • Watch case opener: A specialized tool designed to pry open the watch back without scratching or damaging it.
  • Small precision screwdriver set: Often necessary for removing screws that hold the battery or movement in place.
  • Plastic tweezers: Used to handle the battery safely, avoiding short circuits and preventing corrosion from skin oils.
  • New battery: Ensure you have the correct battery type that matches your Guess watch model.
  • Soft cloth or mat: To protect the watch face and case from scratches during the process.
  • Magnifying glass: Helpful for viewing small screws and components clearly.

Having these tools ready will streamline the replacement process and minimize the risk of damage.

Step-by-Step Guide to Replacing the Battery

Replacing the battery in a Guess watch requires precision and care. Follow these steps carefully:

Open the Watch Case
Place the watch face down on a soft cloth to protect the crystal. Identify the type of case back—snap-off, screw-back, or secured with screws. Use the appropriate case opener tool to gently remove the back cover:

  • For snap-off backs, insert the case opener into the small gap and pry gently.
  • For screw-back cases, use a case wrench or a specialized tool to unscrew.
  • For screw-secured backs, remove the screws using the precision screwdriver.

Remove the Old Battery
Locate the battery inside the watch. If a clip or holder secures it, carefully unscrew or unclip it. Use plastic tweezers to lift the battery out, avoiding contact with metal tools to prevent short circuits.

Insert the New Battery
Confirm the new battery matches the original in size and voltage. Using plastic tweezers, place the new battery in the compartment with the positive (+) side facing the correct direction, usually upward. Secure the battery holder or clip back in place.

Close the Watch Case
Before sealing, ensure the gasket (rubber seal) is properly positioned to maintain water resistance. Snap or screw the back case into place carefully. Avoid forcing it to prevent damage.

Test the Watch
Turn the watch over and check if it is running. Set the time and date as needed.

Common Battery Types Used in Guess Watches

Guess watches commonly use button cell batteries, with variations depending on the model and movement type. Below is a table listing typical battery types and their specifications:

Battery Model Diameter (mm) Height (mm) Voltage (V) Typical Watch Models
SR626SW (377) 6.8 2.6 1.55 Most analog Guess watches

Always verify your watch’s specific battery type by consulting the user manual or the battery currently installed before purchasing a replacement.

Tips for Maintaining Your Guess Watch After Battery Replacement

Proper maintenance following a battery replacement helps extend your Guess watch’s lifespan and ensures optimal performance:

  • Avoid moisture exposure: Make sure the watch back is sealed correctly to maintain water resistance.
  • Clean the case and band regularly: Use a soft cloth to remove dirt and sweat that can degrade materials.
  • Store the watch properly: When not in use, keep it in a dry, cool place away from direct sunlight.

  • Professional servicing: For complex models or if unsure about the replacement, seek professional watchmaker service.

Following these recommendations will keep your Guess watch functioning accurately and looking its best.

Preparing to Replace the Battery in Your Guess Watch

Before beginning the battery replacement process, gather the necessary tools and ensure you are working in a clean, well-lit environment to avoid losing small components. Handling watch parts requires precision and care.

  • Tools Required:
    • Small precision screwdriver set (flathead and Phillips)
    • Case back opener or a thin, flat tool (case knife or plastic pry tool)
    • Tweezers (preferably non-magnetic)
    • Replacement battery (check the exact model number from the old battery or watch manual)
    • Soft cloth or watch holder to prevent scratches
    • Magnifying glass (optional but helpful)
  • Battery Identification:
    Identify the battery type by either:

    • Reading the markings on the current battery inside the watch
    • Consulting the Guess watch manual or manufacturer’s website

Opening the Watch Case to Access the Battery

Guess watches typically have one of three case back types: snap-off, screw-back, or secured with screws. Correctly identifying the case back type is essential to avoid damage.

Case Back Type Description Recommended Opening Method
Snap-Off Thin, flat back panel that snaps into place Use a case knife or thin pry tool to gently lift the back off
Screw-Back Back panel with multiple notches around edge Use a case back wrench or adjustable tool designed for screw backs
Secured with Screws Back panel held by small screws at corners or edges Use an appropriate precision screwdriver to remove screws
  • Procedure:
    1. Place the watch face down on the soft cloth to avoid scratches.
    2. Identify the case back type and select the appropriate tool.
    3. For snap-off backs, insert the case knife under the lip and gently twist to pop it open.
    4. For screw-back cases, align the case back wrench with the notches and turn counterclockwise.
    5. For screw-secured backs, carefully unscrew each screw and store them safely.
  • Important: Avoid applying excessive force to prevent damage to the watch case or internal components.

Removing and Replacing the Battery

Once the case back is removed, you will have access to the watch battery and movement.

  • Identify the Battery Holder:
    Most Guess watches have a small clip or holder securing the battery in place.
  • Removing the Battery:
    • Use non-magnetic tweezers or a small screwdriver to gently lift or slide the clip away from the battery.
    • Carefully remove the old battery without touching other internal components.
  • Inserting the New Battery:
    • Confirm the battery is the exact replacement type.
    • Place the new battery in the same orientation as the old one (usually positive side facing up).
    • Secure the battery by re-engaging the clip or holder.

Verifying the Battery Replacement and Closing the Watch

Before resealing the watch case, ensure the watch is functioning properly.

  • Test the Watch:
    • Observe if the second hand is moving or if the digital display powers on.
    • If the watch does not start, confirm the battery is correctly positioned and making contact.
  • Cleaning:
    Wipe any fingerprints or dust from the inside of the case back and watch surface.
  • Resealing the Case Back:
    • For snap-off backs, align the back cover and press firmly until it snaps into place.
    • For screw-backs, align threads and use the case back wrench to tighten clockwise securely but without over-tightening.
    • For screw-secured backs, replace and tighten all screws evenly.
  • Final Checks:
    • Ensure the case back is fully seated to maintain water resistance.
    • Reset the time and any other watch functions as needed.
