Introduction
Thank you for choosing the SANDA 747 Dual Display Watch. This timepiece combines classic analog aesthetics with modern digital functionality, offering features such as a stopwatch, alarm, LED display, and 50-meter water resistance. This manual provides essential information for setting up, operating, and maintaining your watch to ensure optimal performance and longevity.
1. Setup
1.1 Initial Inspection
Upon receiving your SANDA 747 watch, inspect it for any protective films on the watch face, case back, or strap. Gently peel off any films to reveal the watch's finish. The watch back may have a "QC PASS" sticker, which can be removed.
1.2 Adjusting the Strap and Wearing the Watch
The stainless steel strap features a hidden clasp. To open, gently lift the clasp. To secure, align the two parts of the clasp and press firmly until it clicks into place. If the strap is too long, it may require professional adjustment to remove links for a comfortable fit.
2. Operating Instructions
Your SANDA 747 watch features both an analog display (for traditional timekeeping) and a digital LED display (for various functions). The watch has multiple buttons for operation.
2.1 Button Functions
- Auxiliary Button:
- Long press for 3 seconds: Activates Stopwatch function.
- Stopwatch state: Long press for 3 seconds to clear zero.
- Normal time state: Long press for 3 seconds to switch value (e.g., between 12/24-hour format, or other display modes).
- Mode Button:
- Used for conversion between different modes (e.g., Timing, Timing Alarm, Setting Time, Date, Day, Month).
- In setting modes, pressing this button can increase the value of the selected digit.
- Adjust Pointer Time: This button is used to set the analog hands.
- Time to Show: This button likely activates the LED backlight or cycles through digital display information.
2.2 Setting the Time and Date (Digital Display)
Specific instructions for setting the digital time and date are typically found by entering a "setting mode" using the Mode Button. Once in setting mode, use the Auxiliary Button to select the digit to adjust and the Mode Button to change its value. Repeat for all desired settings (hours, minutes, year, month, day).
2.3 Setting the Analog Time
To set the analog time, use the "Adjust Pointer Time" button. This button typically allows you to advance the hour and minute hands. Press and hold or repeatedly press until the desired time is reached.
2.4 Using the Stopwatch
To activate the stopwatch, long press the Auxiliary Button for 3 seconds. Once in stopwatch mode, use the buttons (likely the Auxiliary and Mode buttons) to start, stop, and reset the timer. Long press the Auxiliary Button for 3 seconds to clear the stopwatch to zero.
2.5 Using the Alarm
Access the alarm setting mode using the Mode Button. Set the desired alarm time using the other buttons to adjust hours and minutes. Ensure the alarm is activated once set.
3. Maintenance
3.1 Water Resistance
Your SANDA 747 watch is rated for 50 meters (5 ATM) water resistance. This means it is suitable for everyday use, such as splashes, rain, and brief immersion in water. However, it is NOT suitable for hot water, warm water bathing, or showering, as water vapor can penetrate the watch and cause damage. Do not operate buttons while the watch is wet or submerged.
3.2 Cleaning
Wipe the watch regularly with a soft, dry cloth to remove dust and smudges. For the stainless steel band, a slightly damp cloth can be used, followed by immediate drying. Avoid using harsh chemicals, solvents, or abrasive cleaners, as these can damage the watch's finish and internal components.
3.3 Battery Information
The watch uses a Japanese original Maxell CR2032 3V battery. The battery endurance is typically 2-3 years, with a standby mode for about 24 months. When the digital display starts to dim or functions become unreliable, it may be time to replace the battery. Battery replacement should ideally be performed by a qualified watch technician to ensure water resistance is maintained.
3.4 General Care
- Avoid exposing the watch to extreme temperatures or direct sunlight for prolonged periods.
- Keep the watch away from strong magnetic fields, which can affect its accuracy.
- Do not expose the watch to any chemical cosmetics or corrosive daily necessities, as these can corrode the plating color of the watch surface.
- Avoid strong impacts or drops.
4. Troubleshooting
- Digital Display is Blank or Dim: The battery may be low or depleted. Consider replacing the battery.
- Analog Hands Not Moving: Check if the crown (if present, though this model uses buttons) is pushed in. If not, the battery might be low, or there could be a mechanical issue.
- Time is Inaccurate: Re-set both the analog and digital times according to the operating instructions. Ensure the watch has not been exposed to strong magnetic fields.
- Water Inside the Watch: If condensation or water droplets appear inside the watch, stop using it immediately and seek professional service. This indicates a breach in water resistance.
For complex issues or if troubleshooting steps do not resolve the problem, please contact customer service for assistance.

6. User Tips
- Read the Manual: Familiarize yourself with all button functions and settings before attempting complex operations.
- Analog vs. Digital: Remember that the analog and digital times are set independently. Ensure both are synchronized if you wish them to display the same time.
- Backlight Usage: The LED display provides a backlight for low-light conditions. Use it sparingly to conserve battery life.
7. Warranty and Support
For any questions, concerns, or issues not covered in this manual, please contact the seller or manufacturer's customer service. Provide your product model (SANDA 747) and a detailed description of the issue for prompt assistance. Do not attempt to open or repair the watch yourself, as this may void any warranty and compromise its water resistance.
