9109.10.10 - With opto-electronic display only

This classification covers complete and assembled electric clock movements specifically designed for alarm clocks, featuring only an opto-electronic display. Such movements are characterized by their integrated electrical power source and mechanism, intended to drive the timekeeping function and activate an alarm. The defining feature for this subcategory is the sole presence of an opto-electronic display, which typically utilizes light-emitting diodes (LEDs) or liquid crystal displays (LCDs) to show the time.

This category is distinguished from its sibling, "Other," which would encompass electric alarm clock movements that do not exclusively rely on an opto-electronic display. The "Other" category would therefore include movements with mechanical hands, analog displays, or combinations of display types beyond just opto-electronic. The emphasis here is on the specific type of visual output: digital and light-based.

As this is a leaf node within the HTS classification, there are no further subcategories. The classification ends with the specific criteria of being an electrically operated, complete and assembled clock movement for alarm clocks, and featuring only an opto-electronic display. Examples within this category would include digital alarm clock mechanisms where the time is displayed solely via LEDs or an LCD screen, and which incorporate the necessary components for an alarm function.
