2. Product Overview
The TX T3C320 watch combines advanced functionality with robust construction. Familiarize yourself with the watch's components before proceeding with setup.

Figure 1: Front view of the TX T3C320 watch. This image displays the white dial, yellow rubber strap, titanium case, and chronograph pushers. The dial features luminous hands, hour markers, and sub-dials for chronograph minutes, 24-hour display, and dual-time zone.
Key Components:
- Crown: Used for setting time and date.
- Pushers (A & B): Operate the chronograph functions.
- Bezel: Unidirectional rotating titanium bezel, typically used for elapsed time measurement.
- Main Dial: Displays hours, minutes, and seconds.
- Sub-dials: Indicate chronograph measurements, 24-hour time, and second time zone.
- Date Window: Displays the current date.
3. Setup and Initial Operation
3.1 Setting the Time
- Pull the crown out to position 2 (the outermost position). The second hand will stop.
- Rotate the crown to move the hour and minute hands to the desired time. Ensure AM/PM is correctly set if applicable (observe the 24-hour sub-dial or date change).
- Push the crown back into position 1 (normal operating position). The second hand will resume movement.
3.2 Setting the Date
- Pull the crown out to position 1 (the first click).
- Rotate the crown to adjust the date. Avoid setting the date between 9 PM and 3 AM, as this can interfere with the automatic date change mechanism.
- Push the crown back into the normal operating position.
3.3 Setting the Second Time Zone
The TX T3C320 features a dedicated sub-dial for a second time zone. Refer to your watch's specific sub-dial configuration for precise adjustment. Typically, this is adjusted independently using a pusher or a specific crown position.
- Identify the pusher or crown position dedicated to the second time zone adjustment.
- Activate the adjustment mode (e.g., press and hold a pusher, or pull crown to a specific position).
- Adjust the second time zone hand to the desired time.
- Deactivate the adjustment mode.
4. Operating the Chronograph
The linear chronograph measures elapsed time up to 4 hours with 1/5 second precision.
- Starting the Chronograph: Press pusher A to start the chronograph. The chronograph second hand and linear minute indicator will begin moving.
- Stopping the Chronograph: Press pusher A again to stop the chronograph. Read the elapsed time from the chronograph second hand and the linear minute indicator.
- Resetting the Chronograph: After stopping, press pusher B to reset all chronograph hands to their zero positions.
- Split Time Function (if applicable): Some chronographs allow for split time measurement. Consult specific watch diagrams if this feature is present and how to operate it.
5. Maintenance and Care
5.1 Water Resistance
Your TX T3C320 watch is water resistant to 100 meters (330 feet). This rating means it is suitable for snorkeling, swimming, and general water activities. It is not suitable for scuba diving. Always ensure the crown is fully pushed in before exposing the watch to water. Do not operate the pushers or crown while the watch is wet or submerged.
5.2 Cleaning
To clean your watch, wipe the case and crystal with a soft, damp cloth. For the rubber strap, mild soap and water can be used, then rinse thoroughly and dry. Avoid using harsh chemicals or abrasive materials.
5.3 Battery Replacement
The watch is powered by a quartz movement, which requires a battery. When the battery is low, the second hand may exhibit an End-of-Life (EOL) indicator (e.g., jumping every few seconds). Battery replacement should be performed by a qualified watch technician to ensure proper sealing and water resistance.
5.4 Storage
When not wearing your watch, store it in a cool, dry place away from direct sunlight and extreme temperatures. Avoid exposing it to strong magnetic fields.
6. Troubleshooting
- Watch not running: Check if the crown is fully pushed in. If the watch still does not run, the battery may need replacement.
- Date not changing: Ensure the time is set correctly, especially the AM/PM cycle. Avoid setting the date during the automatic change period (9 PM - 3 AM).
- Chronograph hands not resetting to zero: This may require a chronograph reset procedure. Consult a service center if a simple reset (press pusher B after stopping) does not work.
- Condensation under crystal: This indicates a loss of water resistance. Immediately take the watch to a service center to prevent further damage.
