The Revolving-Disk-System (R.D.S.) is and invention of Angular Momentum, patented and registered in Switzerland under patent number CH 686988 in 1997.

The R.D.S. Technology enables Angular Momentum to design and develop a wide range of different interesting and useful functions on wrist watches such as "Digital", "GMT", "U.T.C." and "World Time" functions.

Beside of the functional aspect, Angular Momentum time pieces have a face that does not look the same as any other watch face; however, it turns as the time progresses to display the hour. People enjoy the distinct design of watches that utilize angular momentum.
For these reasons, Timeway Europe has chosen Angular Momentum as favorite of the month!
