Setup
Setting the Time
- Pull the crown out to the second click position. The second hand will stop.
- Rotate the crown to set the hour and minute hands to the desired time. Ensure AM/PM is correctly set if your watch has a 24-hour indicator or date changes at midnight.
- Push the crown back into the normal position. The second hand will resume movement.
Setting the Date
- Pull the crown out to the first click position.
- Rotate the crown to set the date. Avoid setting the date between 9:00 PM and 3:00 AM, as this can interfere with the automatic date change mechanism.
- Push the crown back into the normal position.
Adjusting the Band
The stainless steel band of your Invicta watch is designed for a secure fit. For proper sizing, it is recommended to have the band adjusted by a professional jeweler or watch technician. This typically involves removing or adding links to achieve the correct wrist circumference.
Operating the Chronograph
Your Invicta 2645 watch features a chronograph function for measuring elapsed time.
- Start: Press pusher A to start the chronograph. The chronograph second hand will begin to move.
- Stop: Press pusher A again to stop the chronograph. The elapsed time will be indicated by the chronograph hands.
- Reset: After stopping the chronograph, press pusher B to reset all chronograph hands to their zero positions.
- Split Time (if applicable): Some chronographs allow for split time measurement. Refer to specific movement instructions if your model supports this.
Water Resistance
This watch is water resistant to 660 feet (200 meters), making it suitable for professional marine activity and serious surface water sports, but not scuba diving. It is important to ensure the crown is fully pushed in and, if applicable, screwed down before any contact with water. Do not operate the crown or pushers while the watch is submerged in water, as this can compromise the water resistance.
Maintenance
Cleaning
To maintain the appearance of your watch, wipe the case and band regularly with a soft, dry cloth. For stainless steel bands, a slightly damp cloth can be used, followed by a dry cloth. Avoid using harsh chemicals or abrasive materials.
Battery Replacement
Your Invicta 2645 watch is powered by a Swiss Quartz movement, which requires a battery. When the battery life is depleted, the watch may stop or the second hand may jump in irregular intervals (End-of-Life indicator). Battery replacement should be performed by a qualified watch technician to ensure the proper sealing and water resistance of the watch are maintained.
Storage
When not wearing your watch, store it in a cool, dry place away from direct sunlight and strong magnetic fields. The original watch box is ideal for storage.
