- Enter Setting Mode: Press and hold Button A (Mode) for approximately 3-5 seconds until a digit on the display begins to flash. This indicates you are in setting mode.
- Adjust Hours: While the hour digit is flashing, press Button B (Set/Adjust) repeatedly to advance the hour. Observe the AM/PM indicator if present.
- Adjust Minutes: Press Button A (Mode) once to move the flashing indicator to the minute digits. Then, press Button B (Set/Adjust) repeatedly to adjust the minutes.

Note: If your watch features a 24-hour format, the AM/PM indicator will not be present.
4. Operating
Viewing Time and Date:
- Current Time: The watch typically displays the current time (hours and minutes) by default on the main right display.
- Date Display: Press Button A (Mode) briefly to cycle through different display modes. One press should show the date (month/day). Subsequent presses may reveal other functions if available (e.g., seconds, alarm time).
- Return to Time Display: After viewing other modes, the watch will usually revert to the time display automatically after a few seconds, or you can press Button A (Mode) until the time is shown again.
5. Maintenance
Cleaning:
To maintain the appearance of your watch, wipe the case and strap regularly with a soft, dry cloth. For stubborn dirt, a slightly damp cloth can be used, followed by immediate drying. Avoid using harsh chemicals or abrasive cleaners.
Battery Replacement:
The Marea B35138/3 watch is powered by a standard watch battery (e.g., a lithium coin cell like CR2016). When the display becomes dim or stops functioning, the battery may need replacement. It is recommended to have the battery replaced by a qualified watch technician to ensure proper sealing and prevent damage to the internal components.
Water Resistance:
This watch is generally designed to be splash resistant, suitable for daily use such as hand washing or light rain. It is not recommended for swimming, showering, or diving. Avoid prolonged exposure to water.
6. Troubleshooting
- Display is blank or dim: This usually indicates a low battery. Replace the battery as described in the Maintenance section.
- Incorrect time displayed: Re-enter the setting mode and adjust the time and date according to the Setup instructions. Ensure you have selected the correct AM/PM setting if applicable.
- Buttons are unresponsive: Check if the watch is in a specific mode that locks buttons. If not, a low battery or internal malfunction may be the cause. Try replacing the battery first. If the issue persists, contact customer support.
- Condensation inside the display: This indicates a breach in the watch's water resistance. Avoid further water exposure and seek professional service immediately to prevent damage to internal components.
