1. Introduction
Thank you for choosing the OLEVS 2900 Quartz Watch. This manual provides essential information for the proper setup, operation, and maintenance of your new timepiece. Please read it thoroughly before using your watch to ensure optimal performance and longevity.

2. Important Safety Information and Warnings
- Water Resistance: The watch is 30 meters (3ATM) living waterproof. It is equipped with a sealed waterproof ring to enhance its anti-fog function. However, it cannot prevent warm water or hot water from entering. Do not use the watch with hot water or warm water for bathing and showering, as water vapor can enter and damage the watch.
- Chemical Exposure: Do not expose the watch to chemical cosmetics or corrosive daily necessities. These substances can corrode the plating color of the watch surface.
- Measurement Accuracy: The watch size is measured manually, and there may be slight differences from the actual product. The specific physical product shall prevail.
3. Watch Components
Familiarize yourself with the main components of your OLEVS 2900 watch:

- Crown: Located on the right side of the watch case. Used for setting time and date.
- Pushers: Two buttons located above and below the crown. These are typically used for chronograph functions (start/pause, reset).
- Hour Hand: Indicates the hour.
- Minute Hand: Indicates the minute.
- Second Hand: Main second hand for timekeeping.
- Sub-dials: The OLEVS 2900 features multiple sub-dials, including a 60-minute dial (for chronograph), a moon phase dial, and a 24-hour indicator.
- Carved Flywheel: A decorative element on the dial, part of the watch's aesthetic design.
4. Initial Setup
4.1 Time Setting
- Pull the crown out to Position 1.
- Rotate the crown to adjust the hour and minute hands to the correct time.
- Push the crown back to the Normal Position (0) to start timekeeping.
4.2 Date and Day Setting (for Single/Double Calendar Quartz Watch)
Your watch features an auto date and complete calendar function. To set the date and day:
- Pull the crown out to Position 1.
- Rotate the crown to adjust the date and day.
- Important: Avoid adjusting the day and date display between 9:00 PM and 3:00 AM, as this can interfere with the automatic date change mechanism. If you need to reset during this period, first adjust the time outside this window, then set the date/day, and finally reset the time to the correct current time.
4.3 Moon Phase Setting
The moon phase changes as time turns. To set the moon phase, pull the crown out to Position 1 and rotate it until the moon phase display is correct for the current time.
5. Operating Your Watch
5.1 Chronograph Function
Your OLEVS 2900 watch includes a chronograph (stopwatch) function:
- Start/Pause: Press the upper pusher (Timer start/pause) to start or pause the chronograph.
- Reset: Press the lower pusher (Timing reset button) to reset the chronograph to zero.
- The 60-minute sub-dial tracks elapsed minutes during chronograph operation.
5.2 Luminous Feature
The watch hands and markers are coated with HD luminescent material. After absorbing light, they provide strong luminescence, making it easy to read the time in low-light conditions or at night.

6. Care and Maintenance
- Cleaning: Wipe the watch regularly with a soft, dry cloth to remove dust and smudges. For the stainless steel band, a slightly damp cloth can be used, followed by immediate drying.
- Water Exposure: While the watch is 30M living waterproof, avoid prolonged submersion, hot water, or steam. Do not operate the crown or pushers when the watch is wet.
- Temperature Extremes: Avoid exposing the watch to extreme temperatures (hot or cold) or sudden temperature changes, as this can affect the movement and seals.
- Magnetic Fields: Keep the watch away from strong magnetic fields, which can affect the accuracy of the quartz movement.
- Battery: The watch comes with a battery included. When the battery runs out, have it replaced by a qualified watch technician to ensure proper sealing and water resistance.
7. Troubleshooting
- Watch not running: Check if the crown is fully pushed in. If it is, the battery might need replacement.
- Date/Day not changing: Ensure you are not adjusting the date/day between 9:00 PM and 3:00 AM. If the issue persists, the mechanism might require inspection.
- Fogging under glass: This indicates moisture ingress. Stop using the watch immediately and have it inspected by a professional.
- Inaccurate time: If the time is consistently inaccurate, it could be due to a weak battery, exposure to strong magnetic fields, or a need for servicing.
If you encounter any issues not covered here or require assistance with time adjustment, please contact customer service.
