3. Setup
3.1 Setting the Time
- Pull the crown out to the second click position (farthest out).
- Turn the crown to adjust the hour and minute hands to the desired time.
- Push the crown back to the normal position to start the watch.
3.2 Setting the Date
- Pull the crown out to the first click position.
- Turn the crown clockwise or counter-clockwise (depending on the movement) to set the correct date. Avoid setting the date between 9 PM and 3 AM, as this is when the date change mechanism is active and could be damaged.
- Once the date is set, push the crown back to the normal position.
3.3 Adjusting the Bracelet
The stainless steel bracelet can be adjusted to fit your wrist. This typically involves removing or adding links. For precise adjustment, it is recommended to visit a professional watch repair shop or jeweler. Improper adjustment can damage the bracelet or clasp.

4.2 Luminous Feature
The hands and hour markers of your OLEVS G9931 watch are coated with a luminous material. This material absorbs light during the day and emits it in the dark, allowing you to read the time in low-light conditions. The intensity and duration of the glow depend on the exposure to light.
4.3 Water Resistance
This watch is rated for 30 meters (3 ATM) of water resistance. This means it is suitable for daily use and can withstand splashes, rain, and brief immersion in water, such as during hand washing. It is not suitable for swimming, showering, diving, or any activities involving prolonged water exposure or high-pressure water.
- Ensure the crown is fully pushed in before any contact with water.
- Do not operate the crown while the watch is wet or submerged.
5. Maintenance
5.1 Cleaning
To maintain the appearance of your watch, wipe the case and bracelet regularly with a soft, dry cloth. For stainless steel, a slightly damp cloth can be used, followed by a dry cloth. Avoid using chemical cleaners, solvents, or abrasive materials, as these can damage the watch's finish.
5.2 Battery Replacement
The OLEVS G9931 uses a quartz movement, powered by a battery. When the watch stops running, the battery needs to be replaced. Battery life typically ranges from 2 to 3 years. It is recommended to have the battery replaced by a qualified watch technician to ensure the watch's water resistance is maintained and to prevent damage to the internal components.
5.3 Water Resistance Care
The gaskets that ensure water resistance can degrade over time. It is advisable to have the water resistance checked periodically (e.g., every 2-3 years) by a professional, especially if the watch is frequently exposed to water. Avoid exposing the watch to extreme temperature changes, as this can affect the gaskets.
6. Troubleshooting
Watch Not Running
- Check the crown: Ensure the crown is fully pushed in to the normal operating position.
- Battery: If the watch has stopped completely, the battery may need replacement. Consult a professional watch technician.
Date Not Changing
- Time setting: Ensure the time is set correctly, especially past midnight for the date to advance.
- Crown position: Verify the crown is fully pushed in after setting the date.
Condensation Inside the Watch
If you notice condensation inside the watch crystal, this indicates a loss of water resistance. Immediately take the watch to a professional watch repair center to prevent further damage to the movement.
