Changing the battery in a Guess watch involves more than just popping the back open; it requires a careful approach to avoid damaging delicate components. From identifying the right battery type to handling tiny screws and seals, the process demands attention to detail and the right tools. While it might seem daunting at first, gaining a general overview of what’s involved can make the task approachable and even satisfying for watch enthusiasts and casual wearers alike.

In the following sections, you’ll discover the essential steps and precautions for replacing your Guess watch battery safely and efficiently. Whether you prefer to tackle the job yourself or want to understand what to expect when visiting a professional, this guide will prepare you to keep your watch ticking without missing a beat.

Removing the Case Back

Before accessing the battery compartment of your Guess watch, it is essential to remove the case back carefully. Most Guess watches have either a snap-off or screw-down case back, which requires different techniques.

For a snap-off case back, use a thin, flat tool such as a case knife or a small flathead screwdriver. Insert the edge of the tool into the small notch located on the perimeter of the case back. Gently pry upwards to pop the back off. Take care not to scratch or damage the watch case during this process.

If your Guess watch has a screw-down case back, you will need a specialized case back wrench or a multi-prong case opener. Align the prongs with the notches on the case back, and turn counterclockwise to unscrew it. Apply steady, even pressure to avoid slipping or damaging the watch.

When the case back is removed, place it safely aside on a soft surface to prevent scratches or dents. This will allow you to access the battery compartment for replacement.

Identifying and Removing the Old Battery

Once the case back is off, locate the battery inside the watch. It is usually held in place by a small clip or a retaining bar. Before proceeding, note the battery type and orientation to ensure correct replacement.

To remove the battery:

  • Use plastic tweezers or a non-metallic tool to avoid short-circuiting the battery or damaging internal components.
  • Carefully release any clips or retaining bars securing the battery.
  • Gently lift the battery out, noting the position of the positive (+) and negative (-) sides.

Keep the old battery away from children and dispose of it properly according to local regulations.

Selecting the Correct Replacement Battery

Choosing the right battery is crucial for the proper functioning of your Guess watch. The battery type is often stamped on the existing battery or indicated in the watch manual. Common battery types for Guess watches include silver oxide cells such as SR626SW or SR621SW.

Below is a table listing common Guess watch battery types along with their specifications:

Battery Model Diameter (mm) Height (mm) Voltage (V) Common Use
SR626SW (377) 6.8 2.6 1.55 Small analog watches
SR621SW (364) 6.8 2.1 1.55 Ultra-thin watches
SR920SW (371) 9.5 2.1 1.55 Medium size watches

If unsure about the battery model, consult the Guess watch manual or a professional watch technician.

Installing the New Battery

After selecting the correct replacement battery, proceed with installation:

  • Use plastic tweezers to handle the new battery, preventing contamination from oils or static discharge.
  • Position the battery in the compartment with the positive (+) side facing the correct direction, matching the orientation of the old battery.
  • Secure the battery by reattaching the clip or retaining bar firmly but gently.
  • Ensure the battery is seated properly without any movement.

At this stage, it is advisable to check if the watch is functioning by observing the movement of the second hand or digital display.

Reattaching the Case Back

Once the new battery is in place and the watch is working, reattach the case back carefully to maintain water resistance and protect the internal components.

For snap-off case backs:

  • Align the case back with the watch case.
  • Press down evenly using your fingers or a watch press until you hear a click indicating it is securely closed.

For screw-down case backs:

  • Align the threads and begin turning clockwise by hand.
  • Use a case back wrench to tighten securely, but avoid over-tightening to prevent damage.

Verify the case back is flush with the watch case and that there are no gaps.

Testing and Final Checks

After the case back is secured, conduct the following checks to ensure proper battery replacement:

  • Confirm the watch is keeping time accurately.
  • Test any additional functions such as date adjustment, chronograph, or alarms.
  • Check for any signs of moisture or dust inside the watch.
  • If your Guess watch is water-resistant, consider having it pressure tested by a professional to maintain its rating.

By following these steps, you can successfully change the battery in your Guess watch while preserving its performance and longevity.

When opening the case, always apply gentle pressure to avoid scratching or deforming the watch. Work on a soft surface and keep track of any screws or clips removed.

Removing and Replacing the Battery

After gaining access to the watch movement, follow these steps to safely remove and replace the battery:

  • Locate the battery holder, which is often secured by a small clip or screw.
  • If a retaining clip is present, carefully unscrew or unclip it using the appropriate tool.

Handle the new battery with clean hands or gloves to prevent corrosion from oils and dirt. After replacement, check that the watch is functioning correctly before closing the case.

Reassembling the Watch and Testing

Once the new battery is installed, proceed to carefully reassemble the watch:

  • Align the case back with the watch body, ensuring any gasket or rubber seal is correctly positioned to maintain water resistance.
  • For snap-off backs, press firmly and evenly around the edges until it snaps into place.
  • For screw-down backs, replace screws and tighten them securely without over-tightening.
  • For screw-in backs, use the case wrench to carefully screw the back into place, aligning the notches properly.

After reassembly, adjust the time and date settings as needed. Observe the watch over several minutes to confirm that the second hand is moving smoothly and that all functions operate properly.

Additional Tips and Precautions

  • If your Guess watch has water resistance, ensure the gasket is intact or replaced to preserve this feature.
  • Avoid using excessive force at any stage to prevent damage to delicate components.
  • Dispose of the old battery responsibly according to local regulations.

I’m Arron and I’ve always liked pulling things apart just to understand how they work. Watches were a natural obsession. Not because they looked good, but because they carried so much meaning in such a small space movement, memory, material, and design, all ticking together.

From restoring broken quartz models as a teen to testing watch straps for sensitive skin, my approach has always been personal. Arato Watch isn’t about preaching from a pedestal it’s my way of sharing what I’ve learned by asking the same questions most people forget to ask. I believe watches should be understood, not just worn. That’s exactly what this site is here to help you do.
