9102.91.20 - With opto-electronic display only

This HTS classification, 9102.91.20, specifically covers electrically operated wristwatches, pocket watches, and other watches (excluding stop watches) that feature only an opto-electronic display. This means the time is displayed using light-emitting diodes (LEDs) or liquid crystal displays (LCDs), and the watch is powered by electricity, typically a battery. Goods classified here are those where the primary method of time indication is through an electronic, light-based display, and they are designed for wearing on the wrist or carrying in a pocket.

This category is distinguished from its sibling, 9102.91.10, by the type of display. While both are "Other" electrically operated watches, 9102.91.10 would cover those with non-opto-electronic displays, such as traditional analog dials with mechanical hands powered electronically. Therefore, the key differentiator is the absence of a purely light-based time-telling interface in the sibling category.

As a leaf node in the HTS structure, there are no further subcategories under 9102.91.20. This means that any electrically operated watch featuring solely an opto-electronic display and not fitting into the specific categories for stop watches (9102.11 or 9102.19) or those with more than 7 jewels (9102.11) will be classified here. The focus is on the integration of an electronic power source with a light-based display for the primary function of timekeeping in a portable watch format.
