Nerd timepiece! This GSM cellphone wrist watch has a 1-inch OLED screen, and does triband GSM after you drop a SIM card inside. The phone has room for 99 speed dials, and has 40 ringtones built in. Its batteries will last for 80 minutes of standard calls, but the phone has SMS capabilities, and even has Bluetooth for a headset. You know, so no one will think you're a loser while you talk to the wrist.
