The invention concerns a timekeeping clock wherein on the axis of a mobile counter completing a cycle in 11 seconds is mounted a transparent disc ( 42 ) bearing ( 11 ) radial markers ( 44 ). The dial positioned beneath the disc ( 41 ) provides a marking in the form of a marker circle ( 40 ) with ( 10 ) radial markers ( 41 ) numbered 0, 1, 2, 3, 4, 5, 6, 7, 8, 9. At each step of the mobile disc successive alignments occur between a marker of the disc ( 42 ) and a marker of the ring ( 40 ) thereby enabling tenths of seconds elapsed to be displayed anticlockwise. |
