1. Introduction
Thank you for choosing the OLEVS 3633 Men's Quartz Watch. This timepiece combines classic design with modern functionality, featuring a precise quartz movement, dual calendar display, and robust construction. This manual provides essential information for setting up, operating, and maintaining your watch to ensure its longevity and optimal performance.

2. Setup
2.1 Setting Time and Date
- Pull out the crown: Gently pull the crown (the knob on the side of the watch) to its outermost position.
- Set the time: Rotate the crown to adjust the hour and minute hands to the correct time.
- Set the date/day: Push the crown halfway back in. Rotate the crown to adjust the date and day display. Avoid setting the date/day between 9 PM and 3 AM, as this can interfere with the automatic date change mechanism.
- Push in the crown: Once the time and date are set, push the crown fully back into its original position to start the watch.

2.2 Adjusting the Bracelet
The watch comes with a steel bracelet. If adjustment is needed, use the provided meter adjuster tool to remove or add links. It is recommended to have this done by a professional watchmaker to prevent damage.

3. Operating Instructions
3.1 Timekeeping
Your OLEVS 3633 watch is powered by an original quartz movement, ensuring stable and reliable timekeeping. The watch displays hours, minutes, and seconds with precision.
3.2 Dual Calendar Display
The watch features a dual calendar window at the 3 o'clock position, displaying both the day of the week and the date. This function automatically updates daily.

3.3 Luminous Function
The watch hands and markers are equipped with a high-definition luminescent coating, providing a luminous effect for easy readability in low-light conditions. The luminescence charges with exposure to light.

4. Maintenance
4.1 Cleaning
Wipe the watch regularly with a soft, dry cloth to remove dust and smudges. For the stainless steel bracelet, a slightly damp cloth can be used, followed by immediate drying.
4.2 Water Resistance
The OLEVS 3633 watch is 30M (3ATM) water resistant. This means it is suitable for daily use, such as hand washing, rain, or accidental splashes. It is NOT suitable for swimming, diving, or hot water activities (e.g., showering, sauna), as steam and hot water can compromise the seals.

4.3 Battery Replacement
The watch uses a quartz movement, which is battery-powered. When the watch stops or the second hand starts skipping, it's time for a battery replacement. It is recommended to have the battery replaced by a professional watchmaker to ensure proper sealing and maintain water resistance.
4.4 Storage
When not wearing the watch for extended periods, store it in a cool, dry place, away from direct sunlight and strong magnetic fields.
5. 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 the time is set correctly, especially the AM/PM cycle. If the date/day is set during the automatic change period (9 PM - 3 AM), it might not advance properly. Adjust the time past 3 AM and then set the date/day.
- Condensation inside the watch: This indicates a breach in the water resistance. Immediately take the watch to a professional watchmaker for inspection and repair to prevent further damage to the movement.
- Inaccurate timekeeping: While quartz movements are highly accurate, significant deviation might indicate a low battery or a need for servicing.
