Setup
1. Setting the Time and Date
- Pull the Crown: Gently pull the crown (the knob on the side of the watch) out to position 2 (first click) to set the date, or position 3 (second click) to set the time.
- Set the Time: Rotate the crown in position 3 to move the hour and minute hands. Set the time to the desired hour, ensuring AM/PM is correct if your watch has a 24-hour indicator or date changes at midnight.
- Set the Date: If applicable, push the crown to position 2 and rotate it to adjust the date.
- Push the Crown In: Once the time and date are set, push the crown back into position 1 (normal operating position) to start the watch.
2. Adjusting the Strap
The watch features a durable fabric strap. To adjust the fit, simply use the buckle to secure the strap comfortably around your wrist. Ensure it is snug but not overly tight to allow for proper circulation.

Operating the Chronograph
Your Timex Standard Chronograph watch is equipped with a stopwatch function for measuring elapsed time.
- Start/Stop: Press the top pusher (button) located at the 2 o'clock position to start the chronograph. Press it again to stop the chronograph.
- Reset: While the chronograph is stopped, press the bottom pusher (button) located at the 4 o'clock position to reset the chronograph hands to zero.
- Subdials: The watch features multiple subdials. Typically, one subdial tracks seconds, another minutes, and a third may track hours for the chronograph function. Refer to the specific dial markings for precise readings.
Water Resistance
This watch has a water resistance rating of 50 meters (160 feet). This means it is suitable for short periods of recreational swimming, but not for diving or snorkeling. Avoid operating the crown or pushers when the watch is wet or submerged to prevent water ingress.
- Do NOT operate the crown or pushers underwater.
- Do NOT expose to hot water or steam (e.g., hot tubs, saunas).
- Rinse with fresh water after exposure to salt water.
Maintenance
Cleaning Your Watch
To maintain the appearance of your watch, wipe the case and crystal with a soft, damp cloth. For the fabric strap, a mild soap solution and a soft brush can be used, followed by thorough rinsing and air drying. Avoid harsh chemicals or abrasive materials.
Battery Replacement
Your quartz watch is powered by a battery. When the watch stops or the second hand begins to jump erratically (often indicating a low battery), it is time for a battery replacement. It is recommended to have the battery replaced by a qualified watch technician to ensure proper sealing and maintain water resistance.
Storage
When not in use, store your watch in a cool, dry place, away from direct sunlight and extreme temperatures. The original watch box can be used for safe storage.

Troubleshooting
- Watch Not Running:
Ensure the crown is fully pushed in to position 1. If it still does not run, the battery may need replacement.
- Time is Incorrect:
Reset the time as described in the "Setup" section. If the time consistently loses or gains significantly, the watch may require servicing.
- Chronograph Hands Not Resetting to Zero:
Press the reset pusher firmly. If they remain misaligned, consult a watch technician for adjustment.
- Water Inside the Watch:
If you notice condensation or water droplets inside the crystal, immediately take the watch to a qualified service center. Do not attempt to dry it yourself, as this can cause further damage.
