9101.19.20.20 - Of textile material or of base metal, whether or not gold- or silver-plated

This HTS classification, 9101.19.20.20, specifically covers wrist watches that are electrically operated and feature an opto-electronic display only. The crucial defining element for this category is the nature of the display; it must be solely opto-electronic, such as LED or LCD. These watches are further distinguished by their case material, which must be of precious metal or metal clad with precious metal, as per the parent headings.

This subcategory differentiates itself from its sibling, 9101.19.20.40 ("Other"), by the singular requirement of an opto-electronic display. The sibling category would encompass electrically operated wrist watches with precious metal cases that have other types of displays, such as analog or hybrid displays, not exclusively opto-electronic. The specific context of Additional U.S. Note 2 to Chapter 91 is critical here, as it dictates the classification of straps, bands, or bracelets when entered with these watches, whether attached or not, and they will be classified under this specific subheading when they meet the criteria.
