Tamper proof tag for watches

Disclosed is a tamper proof tag and accompanying method for verifying that a watch is authentic and has not been tampered with. The tamper proof tag, when affixed to the watch, ensures that the watch is authentic and prevents a user from tampering with the watch. The tamper proof tag also allows the watch to be worn while the tamper proof tag is affixed to watch and is minimally obstructive to the aesthetics of the watch. This provides a purchasing user with confidence that the watch is authentic, while also allowing the user to try on the watch without having to remove the tamper proof tag. The tamper proof tag also protects the seller from a user that may attempt to tamper with the watch after purchase. For example, the seller may condition returns for a sold watch on the tamper proof tag remaining affixed to the watch.
