Setup
Battery Installation
Your Timex Expedition Vibe Shock watch comes with a Lithium Metal battery (CR2032) included and pre-installed. No initial battery installation is typically required. If the display is dim or unresponsive, the battery may need replacement. Battery replacement should be performed by a qualified watch technician to maintain water resistance.
Initial Time and Date Setting
To set the time and date, refer to the watch's buttons. The watch typically features buttons labeled "MODE/NEXT", "START/SPLIT", "STOP/RESET", and "INDIGLO".

- Use the START/SPLIT or STOP/RESET buttons to adjust the flashing digits (hours, minutes, seconds).
- Press MODE/NEXT to move to the next setting (e.g., date, month, day of week).
- Once all settings are adjusted, press the DONE/SET button (if available, or the MODE/NEXT button again) to exit the setting mode.
Note: Specific button functions may vary slightly. Consult the on-screen prompts for guidance.

Maintenance
Cleaning Your Watch
To clean your watch, wipe it with a soft, damp cloth. For resin straps, mild soap and water can be used. Avoid harsh chemicals or abrasive materials that could damage the watch case or strap.
Water Resistance
This watch is water resistant to 200 meters (660 feet). This rating makes it suitable for professional marine activity and serious surface water sports. It is not suitable for scuba diving.
- Do not operate the watch buttons while submerged in water to maintain water resistance.
- Avoid exposing the watch to extreme temperature changes, which can affect its water resistance.
- After exposure to saltwater, rinse the watch with fresh water and dry it thoroughly.

Troubleshooting
- Watch display is dim or blank: The battery may be low or depleted. Replace the battery (CR2032) by a qualified technician.
- Buttons are unresponsive: Ensure the watch is not in a locked mode. If the issue persists, a soft reset may be required (refer to online manual or contact support).
- Time is inaccurate: Re-set the time and ensure the correct time zone is selected. If the problem continues, the watch may require servicing.
- Water inside the watch: Immediately take the watch to a professional watch repair service. Do not attempt to open the watch yourself, as this will void the warranty and compromise water resistance.
