ABSTRACT:
A portable tracking alarm apparatus in a wrist watch configuration includes a main body and a strap. The main body includes a locator transmitter module, a micro-switch, and a trigger assembly. The strap is used for the user to wear, and has a hook that extends into the main body to hook the trigger assembly, such that the trigger assembly will not contact the micro-switch. When the strap is destroyed to cause the hook parting from the trigger assembly, the trigger assembly will touch and press the micro-switch to make the locator transmitter module emit a warning message.
