9102.91.40 - Having no jewels or only one jewel in the movement

This HTS classification, 9102.91.40, specifically pertains to electrically operated wrist watches, pocket watches, and other watches (excluding those of heading 9101) that contain no jewels or only a single jewel within their movement. The jewel(s) in watch movements serve to reduce friction and wear on critical moving parts. Therefore, the defining characteristic for this subcategory is the minimal use of jewels in the internal mechanism.

This category is distinguished from its sibling, 9102.91.80, which covers "Other" electrically operated watches of this type. The key differentiator lies in the jewel count. While 9102.91.40 strictly applies to watches with zero or one jewel, 9102.91.80 would encompass electrically operated watches with two or more jewels in their movement. This distinction is crucial for accurate tariff application.

As this node is a leaf node, there are no further subcategories. Classification under 9102.91.40 is final based on the presence of an electric mechanism, the classification as a watch (not a clock), and the absence or singularity of jewels in the movement. Examples would include certain basic digital watches or simple analog quartz watches where the movement mechanism utilizes minimal or no jeweled bearings.
