Forget those fossilized SPOT watches. If you want to go all Dick Tracy, check out Seiko's CPC TR-006, a Bluetooth watch that communicates with your cellphone. Currently just a prototype, the watch can receive text messages from your phone, capture Caller ID data so you know who's calling, and adjust ringtones. Pair it with a Bluetooth headset, stick your phone in your bag, and you've got a complete hands-free interface that still gives you access to your phone's main functions.
