Apple will hold a special Apple Watch activity challenge for Veterans Day in the US
This is the iMessage sticker that completing the challenge unlocks
Since Veterans Day is a U.S. holiday, the challenge will be available only for Apple Watch users in the US. However, if you really, really want that badge and sticker, 9to5Mac suggests that you might be able to trick the system into letting you participate in the challenge, even if you're not based in the US, by changing the region on your Apple Watch.
According to 9to5Mac, the challenge will go live for users on November 9th (Thursday). Completing it will unlock a 3D Veterans Day badge that will be visible in the Activity app, as well as a special sticker iMessage.
