2. Safety Information

• Water Resistance: This watch is water-resistant to 100 meters (330 feet). It is suitable for showering, swimming, and snorkeling. Do not operate the crown or pushers while the watch is wet or submerged to prevent water ingress.
• Battery: The watch uses a CR2 battery. Do not attempt to open the watch case or replace the battery yourself unless you have the proper tools and expertise, as this may compromise water resistance and void the warranty. Consult an authorized service center.
• Temperature: Avoid exposing the watch to extreme temperatures (below 0°C/32°F or above 60°C/140°F) or sudden temperature changes, which can affect accuracy and battery life.
• Chemicals: Keep the watch away from solvents, detergents, perfumes, and cosmetics, as these can damage the case, strap, or gaskets.

3. Setup

3.1 Setting Time and Date

1. Pull the Crown: Gently pull the crown (located on the right side of the watch case) out to position 2. The second hand may stop.
2. Set the Time: Rotate the crown clockwise or counter-clockwise to move the hour and minute hands to the desired time. Ensure you set the correct AM/PM for the date change mechanism.
3. Set the Date: Push the crown in slightly to position 1. Rotate the crown to adjust the date display. If the date changes at noon, advance the time by 12 hours.
4. Push the Crown In: Once the time and date are set, push the crown back into position 0 (normal operating position). The second hand will resume movement.

3.2 Altimeter Calibration

For accurate altitude readings, the altimeter must be calibrated regularly, especially when starting a new activity or after significant weather changes. The altimeter measures atmospheric pressure, which changes with both altitude and weather.

1. Find Known Altitude: Locate your current altitude from a reliable source (e.g., a map, GPS device, or local sign).
2. Activate Altimeter Mode: Refer to the watch's specific pusher functions (typically one of the side pushers) to enter altimeter calibration mode. The altimeter hand will likely point to its current reading.
3. Adjust Altimeter: Use the designated pusher(s) to adjust the altimeter hand to match the known altitude.
4. Confirm Calibration: Exit calibration mode. The altimeter is now calibrated to your current location.

4. Operating Instructions

4.1 Reading Time and Date

The watch features a traditional analog display with hour, minute, and second hands. The date window is typically located at the 3 o'clock position.

4.2 Using the Altimeter

Once calibrated, the altimeter will display your current altitude. The specific method to activate and read the altimeter varies by model, but generally involves:

• Activating Altimeter: Press the designated altimeter pusher (refer to watch diagrams if available). The altimeter hand will move to indicate the current altitude.
• Reading Altitude: Read the altitude indicated by the altimeter hand against the corresponding scale on the dial.
• Returning to Time Mode: The watch may automatically return to time mode after a period, or you may need to press the pusher again.

Note: Altitude readings are based on atmospheric pressure and can be affected by weather changes. Recalibrate frequently for best accuracy.

4.3 INDIGLO Night-Light

To illuminate the watch dial in low-light conditions, press and hold the crown (or a designated pusher, depending on the model). The INDIGLO night-light will activate, providing even illumination across the dial. Release the crown/pusher to turn off the light.

5. Maintenance

5.1 Cleaning Your Watch

• Case and Crystal: Wipe the watch case and crystal with a soft, damp cloth. For stubborn dirt, a mild soap solution can be used, followed by rinsing with clean water and thorough drying.
• Stainless Steel Band: Clean the stainless steel band with a soft brush and mild soapy water. Rinse thoroughly and dry completely to prevent water spots or corrosion.
• Avoid: Do not use harsh chemicals, abrasive cleaners, or solvents, as these can damage the watch's finish or seals.

5.2 Battery Replacement

The watch is powered by a CR2 battery. When the battery is low, the second hand may skip seconds or stop entirely. Battery life typically ranges from 2 to 5 years, depending on usage of features like the altimeter and INDIGLO night-light.

It is highly recommended to have the battery replaced by an authorized Timex service center or a qualified watchmaker. This ensures that the correct battery type is used, and the watch's water resistance is maintained by properly sealing the case back.

5.3 Water Resistance Care

To maintain the watch's 100-meter water resistance rating:

• Ensure the crown is fully pushed in at all times when the watch is wet or submerged.
• Do not operate the crown or pushers underwater.
• Have the gaskets checked and replaced periodically (e.g., every 2-3 years or during battery replacement) by a professional.

6. Troubleshooting

• Watch Not Running: Check if the crown is fully pushed in. If it is, the battery may need replacement.
• Incorrect Time/Date: Refer to Section 3.1 to reset the time and date. Ensure the crown is fully pushed in after setting.
• Inaccurate Altimeter Readings: The altimeter requires frequent calibration. Refer to Section 3.2. Significant weather changes can also affect readings.
• INDIGLO Not Working: The battery may be low, or the function may not be activated correctly. Ensure the crown (or designated pusher) is pressed firmly.
• Water Inside Watch: If condensation or water appears inside the watch, immediately take it to an authorized service center. Do not attempt to dry it yourself.
