2. Setup and Initial Use
2.1 Setting the Time and Date
- Unscrew the Crown: Gently unscrew the crown (the knob on the side of the watch) counter-clockwise until it releases from its secured position. This is crucial for maintaining water resistance.
- Set the Date: Pull the crown out to the first click position. Rotate the crown either clockwise or counter-clockwise to adjust the date.
- Set the Time: Pull the crown out to the second click position. Rotate the crown to move the hour and minute hands to the desired time.
- Secure the Crown: Once the time and date are set, push the crown back in and screw it clockwise firmly against the watch case to ensure the water-resistant seal.

2.2 Adjusting the Bracelet
The stainless steel bracelet can be adjusted by adding or removing links to achieve a comfortable fit. This process typically requires specialized tools and is best performed by a qualified watch technician to avoid damaging the band or the watch.

3. Operating the Watch
3.1 Water Resistance
This watch is water-resistant up to 100 meters (330 feet). This makes it suitable for swimming and snorkeling, but not for scuba diving. Always ensure the crown is fully screwed down before exposing the watch to water.

3.2 Unidirectional Rotating Bezel
The watch features a unidirectional rotating bezel. This bezel can be rotated counter-clockwise to mark elapsed time, commonly used for timing dives or other activities. Align the triangle marker on the bezel with the minute hand at the start of an activity, then read the elapsed time from the bezel as the minute hand progresses.

3.3 Luminous Hands and Markers
The hands and hour markers on the dial are treated with luminous material, providing visibility in low-light conditions. Exposure to light will charge the luminous elements, allowing them to glow in the dark.
4. Maintenance
4.1 General Care
- Clean the watch regularly with a soft, damp cloth to remove dirt and perspiration.
- Avoid exposing the watch to extreme temperatures, direct sunlight for prolonged periods, or strong magnetic fields.
- Rinse the watch with fresh water after exposure to saltwater to prevent corrosion.
4.2 Battery Replacement
This watch is powered by a quartz movement, which requires a battery. The battery life typically ranges from 2 to 3 years. When the battery needs replacement, it is recommended to have it done by an authorized Invicta service center or a professional watchmaker to ensure the water resistance is maintained.
4.3 Crown and Water Resistance
The screw-down crown is vital for the watch's water resistance. Always ensure it is fully screwed in after any adjustments. Failure to do so can compromise the watch's water-resistant properties and lead to internal damage.
5. Troubleshooting
5.1 Watch Not Keeping Accurate Time
- Battery: As this is a quartz watch, inaccurate timekeeping often indicates a low battery. Refer to section 4.2 for battery replacement.
- Impact: Severe impacts can affect the internal movement. If the issue persists after battery replacement, consult an authorized service center.
5.2 Moisture Inside the Watch
If moisture or condensation appears under the crystal, it indicates that the water resistance has been compromised. This often occurs if the crown was not properly screwed down before exposure to water. Immediately take the watch to an authorized service center to prevent further damage.
