Removing the Back Cover of the Guess Watch

To access the battery of your Guess watch, you first need to remove the back cover carefully. The method to open the back will depend on whether your watch has a snap-on, screw-down, or screwed-back case.

For snap-on backs, use a watch case knife or a thin, flat tool to gently pry open the back cover at the small indentation along the edge. Insert the blade carefully and twist slightly to lift the cover off without damaging the case or the gasket.

If the watch has a screw-down back, you will need a case wrench or a specialized watch case opener tool. Align the prongs of the wrench with the notches on the case back and turn counterclockwise to unscrew the cover. Take care to maintain steady pressure and avoid slipping.

For backs secured by small screws, use a precision screwdriver to remove each screw evenly. Place the screws safely aside to avoid loss.

Ensure you work on a clean, flat surface with good lighting to avoid misplacing small parts or scratching the watch.

Identifying and Removing the Old Battery

Once the back cover is removed, you will see the battery housed within a battery compartment. Some models may have a retaining clip or a small screw holding the battery in place.

Before removing the battery, note the battery type and orientation. The battery is typically a small, round silver oxide or lithium cell, and the polarity (+/-) is critical for correct installation.

To remove the old battery:

  • Use plastic tweezers or a non-metallic tool to avoid short-circuiting.
  • Gently lift or slide the battery out of its compartment.
  • If a clip or screw holds the battery, carefully disengage it first.

Avoid touching the battery contacts or internal components with bare hands, as oils and static electricity can cause damage.

Choosing the Correct Replacement Battery

Selecting the right replacement battery is essential for proper watch function and longevity. Guess watches commonly use silver oxide batteries, but the exact model can vary.

Refer to the battery code printed on the old battery or consult the Guess watch manual to determine the compatible type.

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

Battery Model Type Voltage Typical Diameter (mm) Typical Thickness (mm) Common Use
SR626SW (377) Silver Oxide 1.55 V 6.8 2.6 Standard quartz watches
SR621SW (364) Silver Oxide 1.55 V 6.8 2.1 Thin watches, smaller movements
CR2032 Lithium 3 V 20.0 3.2 Smartwatch or multi-function Guess models

Always purchase batteries from reputable suppliers to ensure authenticity and avoid leakage or premature failure.

Installing the New Battery

After confirming the correct battery type, it is time to install the replacement. Follow these careful steps to ensure proper installation:

  • Use plastic tweezers or gloves to handle the new battery and avoid contaminating the contacts.
  • Place the battery into the compartment with the correct polarity, typically the positive (+) side facing up.
  • If there was a retaining clip or screw, resecure it gently without over-tightening.
  • Inspect the battery seating to confirm it is flush and stable.

Be mindful not to force the battery into place, as this can damage internal components or the battery itself.

Reassembling the Watch and Testing

Once the new battery is installed, you can proceed to close the watch case:

  • For snap-on backs, align the cover correctly and press firmly around the edges until it snaps back into place. Applying even pressure avoids warping the case.
  • For screw-down backs, use the case wrench to tighten the cover securely but avoid excessive force that could strip the threads.
  • For screw-secured backs, replace and tighten each screw evenly.

After reassembly, test the watch by setting the time and observing the second hand’s movement or digital display function. If the watch does not start, double-check battery orientation and contact cleanliness.

If problems persist, it may indicate additional mechanical or electronic issues requiring professional servicing.
