Sjors' newest 50Gs feature is on the GWS-900-4JR Speedpass G-Shock. This is a limited edition watch that Casio released in 2004. It's a Tough Solar model that is unique in having one of the Speedpass chips embedded inside for paying at the gas pump. It was only released in Japan, and it's not clear if it would be possible to use these watches to pay at the pumps in the US. This G-Shock has a nice red and black design, with a specially engraved case back and custom backlight. Check out the full article for all the details.
