Looks like a smartwatch but only has a gps tracker and password
So basically what you want is a GPS-Receiver(-Shield), a SIM900(-Shield), a Fingerprint-Sensor, a Battery-Pack and a micro-controller. (And of course some kind of server)

Have you made some research for the parts you want to use and considered their size and power consumption? Sounds completely feasible but your Arduino Prototype will look like it fits into a lunch-box. The idea is a good one and worth trying. (albeit I don't know what the password/fingerprint is good for).

But you will have trouble to shrink it into the size of a smartwatch.
