9104.00.25 - With opto-electronic display only

This HTS subheading specifically classifies instrument panel clocks and similar timekeeping devices designed for use in vehicles, aircraft, spacecraft, or vessels. The key defining characteristic for this category is the presence of an opto-electronic display *only*. This means the clock face and time indication are solely generated by electronic means, such as LCD, LED, or other digital display technologies, and do not incorporate traditional mechanical clock movements for time display. The width or diameter of the clock movement must exceed 50 mm, and the unit value must be over $10.

This classification distinguishes itself from its sibling category, "Other," which would encompass instrument panel clocks that do not solely rely on opto-electronic displays or meet the specified value and size criteria. The sibling category would likely include clocks with integrated mechanical components for timekeeping, or those valued at $10 or less, or those with dimensions outside the specified range.

As this is a leaf node, there are no further subcategories. Therefore, classification within this code hinges directly on the presence of an opto-electronic display as the sole time-indicating mechanism, alongside the specified size and value thresholds. Examples would include digital dashboard clocks found in modern automobiles, GPS integrated clocks in aircraft cockpits, or electronic chronometers on ships that exclusively use digital readouts.
