Casio has unveiled a new limited edition NASA-themed G-Shock watch, but you'll have to win a contest if you want to buy it.
The new GW6900NASA24-1 is part of Casio's ongoing celebration of the first ever G-Shock watch, which went on sale 50 years ago. As Casio fan site G-Central explains, this particular model is based on the GW-6900 design, which dates back to 2009.
