2.1 Watch Components
- Crown: Used for setting time and date.
- Pushers (A & B): Used to operate the chronograph functions.
- Hour, Minute, Second Hands: Indicate the current time.
- Date Window: Displays the current date.
- Sub-dials: Chronograph minute/hour counter, 24-hour/alternate time zone dial, and chronograph seconds.
3. Setup
3.1 Initial Activation
Your watch is powered by a Lithium Metal battery, which is included and pre-installed. The watch should begin running upon receipt. If it is not running, ensure the crown is pushed in completely to the '0' position.
3.2 Setting the Time
- Pull the crown out to position '2' (the outermost position). The second hand will stop.
- Turn the crown clockwise or counter-clockwise to move the hour and minute hands to the desired time.
- Push the crown back in to position '0' to start the watch.
3.3 Setting the Date
- Pull the crown out to position '1' (the middle position).
- Turn the crown clockwise to advance the date in the date window.
- Once the correct date is displayed, push the crown back in to position '0'.
Note: Avoid setting the date between 9 PM and 3 AM, as this may interfere with the automatic date change mechanism. If you need to set the date during this period, first set the time outside this window, adjust the date, then reset the time.
3.4 Setting the 24-Hour / Alternate Time Zone Dial
The top-left sub-dial functions as a 24-hour indicator or an alternate time zone display. This dial can be adjusted independently.
- Pull the crown out to position '2'.
- Press and hold pusher 'A' (top pusher) to advance the 24-hour hand. A quick press will advance it by one hour, holding it will advance it continuously.
- To adjust minutes for the alternate time zone, press and hold pusher 'B' (bottom pusher) while the crown is in position '2'. This allows fine adjustment of the 24-hour hand.
- Once the desired 24-hour or alternate time zone is set, push the crown back in to position '0'.
4. Operating Instructions
4.1 Basic Timekeeping
Once the time and date are set, the watch will continuously display the current time. The main second hand sweeps continuously.
4.2 Chronograph Function
The chronograph allows for timing events up to 4 hours. It utilizes the main second hand for chronograph seconds, the lower-left sub-dial for chronograph minutes (10-minute sweep), and the top-left sub-dial (24-hour dial) for chronograph hours (where 1-hour pips become 10-minute markers, allowing up to 4 hours).
- Start: Press pusher 'A' to start the chronograph. The main second hand will begin to move, along with the chronograph minute and hour sub-dials.
- Stop: Press pusher 'A' again to stop the chronograph. The elapsed time will be indicated by the chronograph hands.
- Reset: After stopping, press pusher 'B' to reset all chronograph hands to their zero positions.
- Restart from Zero (Flyback-like): If you press pusher 'B' while the chronograph is running, it will stop and immediately restart from zero upon release. This is an unusual function for continuous timing.
Note: The chronograph is designed for timing longer intervals (1-4 hours) rather than short, precise splits. The lower-left 10-minute sub-dial has a smooth sweep, not a discrete jump per minute.
4.3 Water Resistance
Your Timex Waterbury Chronograph is water resistant up to 100 meters (330 feet). This means it is suitable for showering, swimming, and snorkeling. It is not suitable for scuba diving.
- Ensure the crown is fully pushed in before any contact with water.
- Do not operate the crown or pushers while the watch is wet or submerged.
- After exposure to saltwater, rinse the watch with fresh water and dry thoroughly.
5. Maintenance
5.1 Cleaning
To maintain the appearance of your watch, wipe the case and bracelet regularly with a soft, dry cloth. For stainless steel components, a slightly damp cloth can be used, followed by immediate drying. Avoid using harsh chemicals or abrasive materials.
5.2 Battery Replacement
The watch uses one Lithium Metal battery. When the battery is depleted, the watch will stop running. Battery replacement should be performed by a qualified watch technician to ensure the water resistance seal is maintained.
5.3 Crystal Care
The watch features a Mineral Glass lens. While durable, it can scratch if exposed to sharp objects or impacts. Handle your watch with care to prevent scratches on the crystal.
6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Watch not running | Crown not pushed in; depleted battery. | Ensure crown is fully pushed to position '0'. If still not running, battery may need replacement by a professional. |
| Incorrect time/date | Time/date not set correctly. | Refer to Section 3.2 and 3.3 for setting instructions. |
| Chronograph hands not resetting to zero | Chronograph hands require calibration. | Consult a professional watch repair service for calibration. |
