FIELD: physics; clocks.
SUBSTANCE: invention relates to the clock making industry, particularly to clock-chronographs, which can work in two modes, one of which shows the current time and the other allows for accurate measurement and display duration of an event. Technical outcome is achieved due to that, the chronograph has a first retrograde pointer, which shows tenths of a second of the chronograph, and a second retrograde pointer, which shows hundredths of a second of the chronograph. Hours, minutes and seconds are displayed by corresponding pointers located at the centre of the face.
EFFECT: increased discreteness of displayed time intervals with improvement of readability of the chronograph readings at the same time, which provides the user with fast access to the required information.
