9102.21.25 - Other

This HTS classification covers wrist watches that are not of precious metal or metal clad with precious metal (heading 9101). Specifically, it applies to other wrist watches, meaning those that do not fall under more specific subheadings within the broader category. These watches may or may not include a stopwatch function.

The key defining characteristic of this category is that the watches are self-winding through automatic movement, meaning they are powered by the motion of the wearer's wrist. Furthermore, they are distinguished from their siblings by having a movement that contains no jewels or at most only a single jewel. This contrasts with sibling categories that might specify a different number of jewels or different strap/bracelet materials.

As a leaf node, this classification represents the most granular level of detail for this particular type of watch. It specifically denotes automatic winding wrist watches with either no jewels or only one jewel in their movement. Examples would include basic automatic wrist watches where the movement is minimally jeweled, typically for functional purposes like reducing friction at key pivot points.
