I have confirmed from a few people now that the carded figure will only be available as a free gift to the first 500 people who pre-order the Indiana Jones watches from GSX Watch in Japan.
The pre-order has been open for a while in Japan (earlier this month), so chances are very good that the 500 pieces are already gone. Looks like another one where eBay will be the only chance tof most people, and with the watches going for around $150 bucks, I imagine the few Indy figures that make it to eBay/Yahoo auctions will be pretty pricey.
