The first timekeeper designed specifically for the band's timekeeper, Tama's Rhythm Watch, had everything a drummer needed to make sure the time was right—live and in the studio. The original Rhythm Watch featured enough volume to play with real drums, a large, easy-to-read display, a dial for quick tempo adjustments, separate volumes for quarter notes, eighths and triplets…the list went on and on. So who could ask for more? Well, lots of drummers could and did. So Tama listened to what they wanted and made some changes. The new RW105 now features a backlit display, 30 different memory settings (up from 20), and up to nine different beat divisions (up from 6). The only thing Tama didn't change was the simplicity.
