With the launch of Gran Turismo 5 set for November 24, Sony has teamed up with Swiss watchmaker Tissot, the official timekeeper of NASCAR, to present the Countdown to Launch sweepstakes for Gran Turismo 5.

Each day leading up to the launch of Gran Turismo 5, Sony will be giving away one Tissot PRS 516 watch customized for Gran Turismo. This watch, valued at $495, features a stainless steel case and rubber strap with folding clasp engraved with the GT logo. It's a true collectible that won't be sold in stores; the only way to get it is to win it.

Visit the Events page here to enter, or click on the Tissot countdown banner here on the GT website. One watch will be given away per day leading up to the game's launch. Entrants must re-enter information each day in order to be eligible to win that day.
