9102.99 - Other:

This HTS category, 9102.99, encompasses "Other" wrist watches, pocket watches, and other watches, excluding those covered by heading 9101 (which are typically those with precious metal cases or gold-plated cases). This residual category is intended for watches that do not fall under more specific classifications within heading 9102.

The primary distinction of this category from its sibling, 9102.91, lies in the power source or operation. While 9102.91 specifically addresses electrically operated watches, 9102.99 covers watches that are not electrically operated. This means watches classified here are typically powered by mechanical movements, such as those driven by a wound spring or weights.

Within this broad "Other" category for non-electrically operated watches, further subdivisions are based on the number of jewels present in the movement. The subcategories distinguish between watches with no jewels or up to 7 jewels, those with over 7 but not over 17 jewels, and those with over 17 jewels. The number of jewels in a watch movement is a significant indicator of its precision, durability, and overall quality, and serves as the key criterion for differentiating these subsequent classifications.
