M60M Watch by Roger Kellenberger

M60M, times have changed. Instead of hands (hours/minutes/seconds) one rotating disc shows the time in hours and quarters (marks). The clock face exists as a ring only, the center is completely empty. Using a similar system as the snowboard soft bindings for the wrist, the watch can be worn tight or loose. By pressing the open button the wrist will open it self due to the spring tension of the steel.
