1. Introduction
Thank you for choosing the OLEVS 2900 Trend Men's Quartz Watch. This manual provides detailed instructions for setting up, operating, and maintaining your watch to ensure optimal performance and longevity. Please read this manual carefully before using your watch.

2. Setup
2.1 Unboxing
Carefully remove your OLEVS 2900 watch from its packaging. Inspect the watch for any signs of damage. The package should include the watch and a user manual (this document).
2.2 Time and Date Setting
The OLEVS 2900 features a crown and two push buttons for adjustments. Refer to the diagram below for button identification:

- Setting the Time: Pull the crown out to the second gear position. Rotate the crown to set the hour and minute hands to the correct time. Push the crown back in to the normal position to start the watch.
- Setting the Calendar (Date/Day): Pull the crown out to the first gear position. Rotate the crown to adjust the calendar display. Push the crown back in to the normal position when done.
Note: Avoid setting the date between 9 PM and 3 AM, as this can interfere with the automatic date change mechanism and potentially damage the movement.
2.3 Band Adjustment
The stainless steel bracelet can be adjusted by removing links. This process typically requires specialized tools and is best performed by a professional watchmaker or jeweler to avoid damaging the watch band.
3. Operating Instructions
3.1 Basic Timekeeping
Once the time is set, the watch will keep accurate time using its original quartz movement. Ensure the crown is fully pushed in to maintain water resistance.
3.2 Chronograph Function
The watch features a chronograph (stopwatch) function with a 60-minute sub-dial. Refer to Figure 2 for button locations:
- Start/Pause: Press the top push button to start the chronograph. Press it again to pause.
- Reset: While the chronograph is paused, press the bottom push button to reset the chronograph hands to zero.
3.3 Moon Phase Display
The watch includes a moon phase sub-dial, typically located on the watch face. This feature displays the current phase of the moon. Adjustment of the moon phase is usually done in conjunction with the calendar setting, often by rotating the crown in the first gear position or via a dedicated recessed pusher (if present, not explicitly shown in diagrams).
3.4 Luminous Feature
The hands and markers of your OLEVS 2900 watch are equipped with an HD luminescent coating, providing short absorption and strong luminescence for easy readability in low-light conditions.

3.5 Water Resistance Guidelines
Your OLEVS 2900 watch is rated for 30 meters (3ATM) of water resistance. This means it is suitable for daily use, such as hand washing, rain, and splashes. It is NOT suitable for showering, bathing, swimming, diving, or any water sports.

Important: Do not operate the crown or push buttons when the watch is wet or submerged in water. Avoid exposing the watch to warm water or hot water, as this can compromise the sealed waterproof rings and anti-fog function.
4. Maintenance
4.1 Cleaning
To keep your watch looking its best, wipe the case and band regularly with a soft, dry cloth. For the stainless steel band, a slightly damp cloth can be used, followed by immediate drying. Avoid using harsh chemicals or abrasive materials.
4.2 Battery
The OLEVS 2900 uses a quartz movement and is powered by a battery. When the watch stops or the second hand starts skipping, it indicates a low battery. Battery replacement should be performed by a qualified watch technician to ensure proper sealing and water resistance.
4.3 General Care
- Avoid extreme temperatures and sudden temperature changes.
- Keep the watch away from strong magnetic fields, as they can affect the accuracy of the quartz movement.
- Protect the watch from impacts and drops.
- Ensure the crown is always pushed in when not adjusting the time or date.
5. Troubleshooting
5.1 Watch Not Running
- Check if the crown is fully pushed in. If it's pulled out, the watch will not run.
- The battery may be depleted. Refer to section 4.2 for battery information.
5.2 Time Inaccurate
- Ensure the time was set correctly (refer to section 2.2).
- Exposure to strong magnetic fields can affect accuracy. Keep the watch away from magnets.
- A low battery can also cause irregular timekeeping.
5.3 Chronograph Not Resetting to Zero
- Ensure the chronograph is paused before attempting to reset (refer to section 3.2).
- If the issue persists, a professional adjustment may be required.
