9105.29.30 - Having over one jewel

This classification, 9105.29.30, specifically pertains to "Other clocks" within the broader category of wall clocks. The defining characteristic of goods falling under this subheading is that they are wall clocks incorporating a movement with over one jewel. These jewels, typically synthetic rubies or sapphires, are strategically placed within the clock's movement to reduce friction and wear on critical components, thereby enhancing accuracy and longevity.

This category is distinguished from its sibling, 9105.29.20, by the presence of more than a single jewel in the movement. While both subheadings cover wall clocks with movements measuring not over 50 mm in width or diameter and designed to operate for over 47 hours without rewinding, the jewel count is the sole differentiating factor. Therefore, wall clocks with no jewels or only one jewel would be classified under 9105.29.20, whereas those possessing two or more jewels fall into this subheading.

As this is a leaf node, there are no further subcategories to introduce. Classification under 9105.29.30 is therefore final for wall clocks meeting the specified criteria of size, power reserve, and the presence of multiple jewels in their movement. Examples would include decorative wall clocks or specialized timekeeping devices where the precision afforded by a jeweled movement is a key operational feature.
