Abstract (en)
[origin: EP2602672A1] The wheel (40) has a ratchet (42) and a central hub. A superstructure is arranged coaxial to the column wheel, where the superstructure comprises a set of radial arms, and a set of columns that is parallel to an axis of rotation of the column wheel. The set of columns is regularly distributed along a circumference of the column wheel. A width of the columns measured between a leading edge and a trailing edge is larger than a width of openings between the columns. A width of the arms at a narrowest point is less than half the width of the columns. An independent claim is also included for a stop watch.
