In addition to these tools, you should work in a clean, well-lit environment to prevent losing small parts and to ensure precise handling.

Locating and Opening the Case Back

The Timex Expedition typically features either a snap-off or screw-down case back. Identifying the type of case back is the first step in gaining access to the battery compartment.

  • Snap-off case backs usually have a small indentation or lip on the edge where a case opener or a thin blade can be inserted to pry it open gently.
  • Screw-down case backs have multiple notches or grooves around the edge designed to be turned with a specialized case wrench or a suitable tool to unscrew the back.

When opening the case back, apply gentle, steady pressure to avoid slipping and scratching the watch. If the case back is resistant, do not force it; instead, verify you are using the correct tool or consider consulting a professional.

Removing the Old Battery Safely

Once the case back is removed, you will see the battery secured in its compartment, often held by a small clip or retainer.

  • Use tweezers to carefully lift or slide the clip away, taking care not to damage the surrounding components.
  • Gently remove the old battery with the tweezers, avoiding contact with internal electronic parts.
  • Note the battery orientation (usually marked with a “+” sign facing up) to ensure correct installation of the new battery.

If the battery is corroded or dirty, it’s advisable to clean the compartment with a dry cloth or a cotton swab lightly moistened with isopropyl alcohol.

Choosing the Correct Replacement Battery

Selecting the appropriate replacement battery is crucial for optimal performance and longevity. Timex Expedition watches typically use silver oxide button cell batteries, but the exact model varies by watch type.

Below is a table listing common Timex Expedition battery types and their specifications:

Battery Model Type Voltage Typical Capacity (mAh) Compatible Timex Models
SR626SW (377) Silver Oxide 1.55 V 28 Most Analog Expedition Watches
CR2032 Lithium 3 V 220 Digital & Compass Models
SR920SW (370) Silver Oxide 1.55 V 33 Some Analog Models with Dual Time

Always confirm the battery type by checking the existing battery or consulting your watch’s manual to avoid compatibility issues.

Installing the New Battery

Place the new battery into the compartment with the correct polarity orientation, matching the “+” side as noted during removal.

  • Use plastic-tipped tweezers or fingers to avoid shorting the battery.
  • Carefully replace the battery retainer clip to secure the battery firmly in place.

After the battery is installed, check to see if the watch hands or digital display start functioning immediately, indicating proper installation.

Sealing the Watch Case Back

Reattaching the case back correctly is vital to maintain water resistance and protect the internal components.

  • For snap-off backs, align the case back properly with the watch case and press firmly until it snaps into place. You may need to apply even pressure with your thumbs or a watch press tool.
  • For screw-down backs, place the case back on and turn it clockwise using the appropriate tool, tightening securely but not excessively to avoid stripping the threads.

Before sealing, inspect the gasket or rubber seal around the case back. If damaged or worn, replace it to maintain water resistance.

Testing the Watch Functionality

Once the watch is reassembled, test its functions thoroughly:

  • Verify the hands move correctly or that the digital display is operational.
  • Check all functions such as alarms, chronographs, or backlight if applicable.
  • Set the time and date to confirm the watch responds accurately to adjustments.

If the watch does not work after battery replacement, recheck the battery orientation, ensure the battery is new and fully charged, and confirm the case back is properly sealed. If problems persist, professional servicing may be necessary.
