The Aquarius was the first major release of an offstring yo-yo by YoYoJam. While the OS1 came first, it was not a major release. Aquarius was discontinued at the end of 2002, to be replaced by the Free Agent. Resurrected in the summer of 2004 after problems with the newer models.
Pictured here is a release from October of 2005. A different logo design from the previous release of the Aquarius.
