3. Setup
3.1 Adjusting the Band

3.2 Initial Time and Date Setting
To set the time and date, locate the crown on the right side of the watch case. The crown typically has three positions:
- Position 0 (Pushed In): Normal operating position.
- Position 1 (Pulled Out One Click): Used for setting the date.
- Position 2 (Pulled Out Two Clicks): Used for setting the time.
4. Operating Instructions
4.1 Setting Time and Date
- Setting the Time: Gently pull the crown out to Position 2. Rotate the crown clockwise or counter-clockwise to move the hour and minute hands to the desired time. Once set, push the crown back to Position 0.
- Setting the Date: Gently pull the crown out to Position 1. Rotate the crown to adjust the date. Avoid setting the date between 9:00 PM and 3:00 AM, as this may interfere with the automatic date change mechanism. Once set, push the crown back to Position 0.
4.2 Using the Chronograph Function
The chronograph function allows you to measure elapsed time. Your watch features three sub-dials for seconds, minutes, and a 24-hour indicator.
- Start/Stop: Press the top pusher (button) on the side of the watch case to start the chronograph. Press it again to stop the measurement.
- Reset: While the chronograph is stopped, press the bottom pusher to reset all chronograph hands back to their zero positions.
4.3 Understanding the Moon Phase / 24-Hour Sub-dial
The sub-dial typically located at the 6 o'clock or 9 o'clock position (refer to your specific dial layout) indicates the 24-hour cycle, often represented with a sun and moon icon. This sub-dial helps differentiate between AM and PM when setting the time, especially for the date change mechanism.
5. Maintenance
5.1 Water Resistance
Your RORIOS watch is rated for 30 meters (3 ATM) of water resistance. This means it is suitable for everyday use and can withstand splashes, rain, and hand-washing. It is not designed for showering, bathing, swimming, diving, or any activities involving prolonged water immersion. Ensure the crown is fully pushed in before any contact with water.
5.2 Cleaning Your Watch
To maintain the appearance of your watch:
- Wipe the case and crystal with a soft, dry, lint-free cloth regularly.
- For the stainless steel band, you can use a slightly damp cloth and mild soap, then dry thoroughly. Avoid harsh chemicals or abrasive materials.
5.3 Battery Replacement
The watch is powered by a quartz battery. When the watch stops running, it indicates the battery needs replacement. It is highly recommended to have the battery replaced by a qualified watch technician to ensure proper sealing and maintain water resistance.

- Watch Not Running: Check if the crown is fully pushed in to Position 0. If it is, the battery may need replacement.

- Chronograph Hands Not Resetting to Zero: Try pressing the bottom pusher firmly. If the issue persists, a professional adjustment may be required.
