9101.29.40 - With movement measuring over 15.2 mm

This HTS classification covers wrist watches and other watches, including stop watches, that feature a case made of precious metal or metal clad with precious metal. Specifically, this category pertains to other wrist watches, excluding those that are pocket watches or exclusively stop watches. The defining characteristic of watches falling under 9101.29.40 is the dimension of their movement.

The key differentiator for this specific classification lies in the size of the watch's internal movement. Watches classified under 9101.29.40 possess a movement measuring over 15.2 millimeters. This distinguishes them from their sibling category, 9101.29.30, which covers watches with movements measuring not over 15.2 millimeters. Both categories, however, share the commonalities of having a precious metal or clad precious metal case and falling within the broader group of other wrist watches with more than 7 but not over 17 jewels in the movement, and a movement valued not over $15 each.

As this is a leaf node in the HTS classification, there are no further subcategories to introduce. Therefore, the classification is complete at this level, requiring only the precise measurement of the movement to accurately assign goods to this code, provided all other criteria of the parent categories (precious metal case, jewel count, and movement value) are met.
