Breitling Emergency Watch

Boy, I bet Jack and Sawyer wish they had one of these. Designed for pilots and aircrews, the Breitling Emergency 43mm Chronograph Watch ($4,700) has a built-in Distress Transmitter that broadcasts a signal on the 121.5 MHz aircraft emergency frequency. After your plane goes down and you've woken up on the island, just unscrew the watch's protective cap, pull out the antenna and rescuers should be right over to save your ass. But if you're not rescued in the first couple of days, start looking for a hatch — the watch can only broadcast for 48 hours.
