9102.21.90 - Other

This HTS category, 9102.21.90, covers "Other" wrist watches that feature automatic winding and a movement containing over 17 jewels, but are not classified under the sibling category 9102.21.70. Specifically, this classification applies to automatic, jeweled wrist watches where the strap, band, or bracelet is made of materials other than textile or base metal (including gold- or silver-plated base metal). Examples would include wrist watches with automatic winding, more than 17 jewels, and bands made from leather, plastic, rubber, or precious metals.

The defining characteristic that distinguishes 9102.21.90 from its sibling, 9102.21.70, lies solely in the material composition of the watch band. While both subcategories fall under automatic winding wrist watches with over 17 jewels, 9102.21.70 is reserved for those with textile or base metal bands. Therefore, the classification hinges on whether the band is constructed from these specified materials or from any other permissible material.

As this is a leaf node within the HTS structure, there are no further subcategories under 9102.21.90. This signifies that all wrist watches meeting the criteria of automatic winding, over 17 jewels, and a band material *other than* textile or base metal are definitively classified here. The classification process for these specific watches concludes at this level, with the distinction from other categories being the primary determinant.
