2.1 Adjusting the Watch Band

The watch features a stainless steel band with a foldover clasp. To ensure a comfortable fit, the band may need to be adjusted by removing or adding links.

• A link bar remover tool is typically included with the watch for this purpose.
• Carefully use the tool to push out the pins from the links you wish to remove.
• Reassemble the band by inserting the pins back into place.
• Caution: Band adjustment can be delicate. If you are unsure, it is recommended to seek assistance from a professional jeweler to avoid damaging the watch band or the spring bars.

3. Operation

3.1 Reading the Time (Binary Display)

The MASTOP Binary Matrix Watch displays time using a unique LED binary system. The display is not continuously lit to conserve battery life.

• To view the time, press the button located on the side of the watch case. The LEDs will illuminate.
• The left column of LEDs represents the hours (HR), from 1 to 12.
• The right column of LEDs represents the minutes (MIN), in increments of 5, from 05 to 60.
• Each lit LED corresponds to the number next to it. For example, if the LED next to '09' is lit in the HR column, the hour is 9. If the LED next to '35' is lit in the MIN column, the minutes are 35.

2. Press and hold the bottom button (often labeled 'B' or 'Mode') until the hour display begins to flash.
3. Use the top button to adjust the hour.
4. Press the bottom button again to switch to minute adjustment.
5. Use the top button to adjust the minutes.

To clean your watch, wipe it gently 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 materials.

The watch is powered by a CR2032 battery. When the display becomes dim or stops functioning, the battery may need replacement.
