Setup
Before using your Timex TW5M55700 watch, follow these steps for initial setup:
- Initial Power On: The watch should be powered on from the factory. If the display is blank, ensure no plastic tab is obstructing the battery contact.
- Setting Time and Date:
- Press the MODE button repeatedly until you reach the Time Set mode (often indicated by flashing digits).
- Use the START and RESET buttons to adjust the hours, minutes, and date. The MODE button typically cycles through the settings (hours, minutes, month, day, year).
- Once all settings are correct, press MODE to exit Time Set mode.
- Personal Information (if applicable): While this model primarily focuses on step tracking, some activity trackers allow input of personal data like stride length or weight for more accurate calorie calculations. Refer to the on-screen prompts if available after initial time setting.
Operating Instructions
Understand the functions of your watch's buttons and display modes.
Button Functions
- MODE Button: Cycles through different display modes (e.g., Time, Step Tracker, Stopwatch, Alarm).
- INDIGLO Button: Activates the Indiglo night-light for illumination of the display.
- START Button: Used to start/stop functions in certain modes (e.g., stopwatch) or to increment values during setting.
- RESET Button: Used to reset functions (e.g., stopwatch) or to decrement values during setting.
Activity Tracking (Steps)
Your watch is equipped with an integrated step tracker. It automatically counts your steps throughout the day.
- Viewing Steps: Press the MODE button until the display shows the 'Steps' indicator and your current step count.
- Resetting Steps: Step counts typically reset automatically at midnight. If you need to manually reset the step counter, navigate to the Step Tracker mode and hold down the RESET button for a few seconds until the count clears.
Indiglo Night-Light
To illuminate the watch display in low-light conditions, press the INDIGLO button. The light will remain on for a few seconds.
Maintenance
Proper care ensures the longevity and performance of your Timex watch.
Water Resistance
This watch is water resistant up to 30 meters (3 ATM). This means it is suitable for splashes or brief immersion in water, but not for swimming, showering, or diving. Do not operate buttons while the watch is wet.
Battery Replacement
The watch uses a CR2032 battery. When the display dims or functions become erratic, it's time to replace the battery. Battery replacement should ideally be performed by a qualified watch technician to ensure proper sealing and maintain water resistance.

Cleaning
Clean your watch regularly with a soft, damp cloth. Avoid using harsh chemicals or abrasive materials that could damage the watch case or strap.
Troubleshooting
If you encounter issues with your watch, try these common troubleshooting steps:
- Blank Display: Check if the battery needs replacement. If recently replaced, ensure it is inserted correctly.
- Incorrect Time/Date: Re-enter the Time Set mode and adjust the settings as described in the Setup section.
- Step Tracker Not Counting: Ensure you are in the correct mode to view steps. If the issue persists, a battery replacement might be necessary, or a soft reset (if available for your model, often by holding all buttons simultaneously for a few seconds) could resolve it.
- Indiglo Not Working: This is often an indication of a low battery. Replace the battery if other functions are also affected.
