I haven't researched the watches as of yet. My first requirement is that the watch is rugged. Normall I carry a Casio G-shock but the bands on that thing only last me a day.<br><br>Secondly I need to find one that emits a beacon of some sort. The whole premise is that I have been abducted or am trapped in a building and I can now signal rescue workers whether unconscius or not.<br><br>I've heard a rumor that there is a mini-epirb that you where as a watch.
