9101.21.50 - Other

This HTS category, 9101.21.50, encompasses "Other" wrist watches with cases made of precious metal or metal clad with precious metal, which feature automatic winding mechanisms and have over 17 jewels in their movement. These are distinct from watches that may have different jewel counts or winding mechanisms, as well as those not made of precious metal or clad thereof. The "Other" designation here implies it captures wrist watches not otherwise specifically detailed within preceding subheadings at this level, provided they meet the material, winding, and jewel count criteria.

It is crucial to differentiate this specific classification from its sibling category. The sibling category pertains to straps, bands, or bracelets that are entered with watches under subheading 9101.21.50 and are to be classified therewith. While these accessories are related to the watches classified here, they are treated as a separate, albeit associated, classification item, often governed by specific additional U.S. notes regarding their classification alongside the watch itself.

As this is a leaf node within the HTS structure, there are no further subcategories for this specific code. Therefore, classification under 9101.21.50 is final for qualifying wrist watches. Classification hinges on the precise composition of the case (precious metal or clad precious metal), the presence of an automatic winding system, and a movement containing more than 17 jewels. The physical construction and internal mechanism are the primary determinants for goods falling under this category.
