Setting the Time and Date
- Pull out the crown: Gently pull the crown (the knob on the side of the watch) to the first or second click position. The number of clicks depends on whether your watch has a date function.
- Set the date (if applicable): If the crown is in the first click position, turn it clockwise or counter-clockwise to adjust the date.
- Set the time: Pull the crown out to the second click position. Turn the crown to move the hands clockwise until the correct time is displayed. Ensure you differentiate between AM and PM for watches with a date function, as the date typically changes around midnight.
- Push in the crown: Once the time and date are set, push the crown back into its original position to start the watch movement.
Adjusting the Band
The polyurethane band features a buckle closure. Adjust the band by selecting the appropriate hole for a comfortable and secure fit on your wrist. The band is designed to be durable and comfortable for daily wear and activities like swimming.

Operating the Watch
Chronograph Function
The Invicta Speedway watch is equipped with a chronograph feature, indicated by the trio of subdials on the watch face. These subdials allow for precise measurement of elapsed time.
- Start/Stop: Press the top pusher button (usually located at the 2 o'clock position) to start and stop the chronograph.
- Reset: Press the bottom pusher button (usually located at the 4 o'clock position) to reset the chronograph hands to zero. This can only be done when the chronograph is stopped.
Water Resistance
This watch is water resistant to 100 meters (330 feet). This rating makes it suitable for swimming and snorkeling. However, it is not recommended for scuba diving. To maintain water resistance, ensure the crown is fully pushed in before any contact with water. Avoid operating the pushers or crown while the watch is wet or submerged.
Care and Maintenance
- Cleaning: Wipe the watch case and band regularly with a soft, damp cloth to remove dirt and perspiration. For the polyurethane band, mild soap and water can be used, followed by thorough rinsing and drying.
- Avoid Chemicals: Do not expose the watch to harsh chemicals, solvents, or detergents, as these can damage the case, band, or seals.
- Temperature Extremes: Avoid exposing the watch to extreme temperatures (hot or cold) or sudden temperature changes, which can affect the watch's accuracy and water resistance.
- Battery Replacement: The watch is powered by a product-specific battery. When the battery needs replacement, it is recommended to have it replaced by a qualified watch technician to ensure proper sealing and maintain water resistance.
- Storage: When not in use, store the watch in a cool, dry place, away from direct sunlight and strong magnetic fields.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Watch stops or runs intermittently | Depleted battery | Replace the battery (recommended by a professional). |
| Time is inaccurate | Weak battery, exposure to strong magnetic fields, or impact. | Replace battery, demagnetize the watch, or have it inspected by a professional. |
| Water inside the watch | Crown not fully pushed in, seals compromised, or exposed to water beyond rating. | Immediately take the watch to a professional for inspection and repair to prevent further damage. |
