Heading 8517 covers telephone sets and other apparatus for the transmission or reception of voice, images, or other data, including apparatus for communication in a wired or wireless network. Heading 9102 covers wrist watches, pocket watches, and other watches, including stop watches, other than those of heading 9101. A smartwatch is both: it tells the time, and it transmits and receives data. The tariff schedule does not have a heading for things that are both, so the classification has to choose, and the choice is made by the General Rules of Interpretation.
The rule that decides it is GRI 3(b), for composite goods and sets: when a good is classifiable under two or more headings, it is classified as if it consisted of the component that gives it its essential character. The question is not what the device looks like, or what it is called, or what it costs. It is what the device does in use, and which function is essential to that use.
CBP's rulings apply that test consistently. The Apple Watch went to 8517.62.00 in HQ H260060, dated 14 July 2015. The Movado M1 Bold smart watch went to the same subheading in HQ H265038. Kronaby hybrid smartwatches with analog faces went to 8517.62.00 in HQ H285617. The Timex Metropolitan+, an analog watch with step tracking over Bluetooth, went to 9102.11.45 in HQ H271909. The pattern is the test, applied four times.
In the Apple Watch ruling, CBP found that the radio transceiver gave the essential character because the core functions depend on the wireless link to a paired phone. The watch receives notifications, takes calls, streams data, and runs apps, and none of that works without the radio. The timekeeping is real, but it is not the function that defines the device in use. A watch that tells time and does little else is a watch. A watch whose core functions need the radio is a data device that also tells time.
The Kronaby ruling sharpens the point. The time on a Kronaby hybrid was adjusted through the app, and it could not be adjusted manually on the watch after a connection interruption. The device was dependent on the phone for a function as basic as setting the time, which made the dependence visible even to a user who only wanted a watch. When the phone link is load-bearing for the device's own basic functions, the essential character is the link.
The Timex ruling shows the other side. The Metropolitan+ kept its essential character as an analog timepiece because its data functions were ancillary: step tracking over Bluetooth, with the watch working fully as a watch without the link. The data was an addition to a watch, not the reason for the watch. That is the line: does the device need the radio to be itself, or does it carry the radio as an extra?
Start with the functions, not the marketing. List what the device does, and mark which functions need the wireless link and which work without it. If the core functions, the ones the buyer pays for, stop working without the link, the essential character is the radio and the heading is 8517. If the device works fully as a watch without the link, and the data functions are additions, the heading is 9102.
Check the rulings for the nearest product, not just the heading. CBP's CROSS database holds the rulings, and the four above are the anchors: H260060, H265038, H271909, and H285617. A device closer to the Apple Watch than to the Timex belongs in 8517. A device closer to the Timex belongs in 9102. The comparison is the classification.
And remember that rulings bind only for the products and parties they cover, and CBP can modify or revoke them. Check CROSS for later rulings citing the same subheadings before relying on one, and when the device is genuinely close to the line, consider a binding ruling request of your own. A classification that turns on essential character is a classification that turns on facts, and facts are worth confirming before the entry is filed.

It depends on the device. CBP has classified the Apple Watch and similar smartwatches in 8517.62.00, as apparatus for the transmission or reception of data. A simpler connected watch whose data functions are ancillary, like the Timex Metropolitan+, was classified in 9102.11.45 as a wrist watch.
Essential character under GRI 3(b). When the device's core functions depend on the wireless link to a paired phone, the radio gives the essential character and the heading is 8517. When the device works fully as a watch without the link, the heading is 9102.
General Rule of Interpretation 3(b) says that when a good is classifiable under two or more headings, it is classified as if it consisted of the component that gives it its essential character. For a smartwatch, that means asking which function defines the device in use.
A ruling binds only for the product and party it covers, and CBP can modify or revoke it. Use the published rulings as the nearest comparison for your device, and check CROSS for later rulings on the same subheadings before relying on one.
