Thanko introduces two new MP3 watches, the 256MB “AMP60256S ” ($133) and 512MB “AMP60512S” ($167). Powered by a lithium ion battery, these watches get up to 2 hours of continuous playback fully charged. One negative: they only support USB 1.1, meaning slow data transfer rates. A voice recorder is also included which records at 128kbps, 44Khz sampling frequency. Both models will be released on February 18th in Japan.
