Another hint tells us the iWatch is coming: Apple extends its trademark to cover jewelry and watches
Now, back to the trademark filing, we ought to say that international agreement rules for 45 different classes of products. Apple has specifically expanded Class 14 trademark protection that aggregates goods like jewelry, watches, badges, necklaces, chains, sculpture and decorations. Cupertino has actually expanded its trademark to that new class in multiple countries - Ecuador is the latest, but previously, Apple has also filed the same application in the United Kingdom, Mexico, and Norway.
Interestingly, Apple has not filed such an application in its prime market, the United States. Coincidentally, Apple is not covered at all under Class 14 (which includes smartwatches) in the US.
