2. Setup
2.1 Initial Power On and Battery
Your watch comes with a pre-installed Lithium Metal battery. The watch should be operational upon removal from its packaging. If the digital display is blank or the analog hands are not moving, the battery may need to be activated or replaced. Consult the 'Maintenance' section for battery information.
2.2 Setting the Analog Time
- Pull out the crown (the small knob on the side of the watch case) to the outermost position.
- Rotate the crown clockwise or counter-clockwise to set the analog hour and minute hands to the desired time.
- Once the time is set, push the crown back in to its original position to start the analog movement.
2.3 Setting the Digital Time and Date
The digital display offers various modes. Use the 'MODE' button (typically on the bottom left) to cycle through them. To set the digital time and date:
- Press the 'MODE' button until you reach the Time Setting mode (often indicated by flashing digits).
- Use the 'RESET' button (typically top right) to select the digit or setting you wish to adjust (e.g., hours, minutes, year, month, day).
- Use the 'START/STOP' button (typically bottom right) to increase the selected value. Hold to advance rapidly.
- Once all settings are correct, press the 'MODE' button again to exit the setting mode.

3.5 Water Resistance
This watch is water-resistant up to 330 feet (100 meters). This means it is suitable for showering, swimming, and snorkeling. It is not suitable for scuba diving. Do not operate any buttons while the watch is wet or submerged, as this can compromise the water resistance.
4. Maintenance
4.1 Cleaning Your Watch
To maintain the appearance of your watch, wipe it regularly with a soft, dry cloth. For resin bands, a damp cloth with mild soap can be used, followed by rinsing with clean water and drying thoroughly. Avoid harsh chemicals or abrasive materials.
4.2 Battery Replacement
The watch uses 1 Lithium Metal battery. When the display dims or the watch stops functioning, the battery may need replacement. Battery replacement should ideally be performed by a qualified watch technician to ensure proper sealing and maintain water resistance. Attempting to replace the battery yourself may void the warranty and compromise the watch's water resistance.
4.3 Storage
When not in use, store your watch in a cool, dry place away from direct sunlight, extreme temperatures, and strong magnetic fields.
5. Troubleshooting
- Watch not running / Digital display blank: Check if the battery needs replacement (refer to Section 4.2). Ensure the crown is pushed in completely for analog movement.
- Incorrect time: Re-set both analog and digital times following instructions in Section 2.
- Buttons not responding: Ensure the watch is not in a locked mode (if applicable, though not a standard feature for this model). If submerged, wait until dry before operating buttons.
- Fogging under crystal: This may indicate a loss of water resistance. Avoid further water exposure and seek professional inspection.
