Abstract

The minute counter of the chronegraph uses a scale (9) extending from 0 to 10 with a coaxial pointer (10) describing one revolution every ten minutes. The hour counter has a scale (11) covering at least an hour and divided into graduations of at least 10 minutes each, the pointer (12) also being coaxially mounted and circulating according to the number of hours covered by the scale. The arrangement includes a chromagraphic mechanism driven by a first gudgeon point of the clockwork and driving the pointers. A circular week number display has 52 or 53 divisions. The week mechanism causes a relative movement between the pointer and the scale. This relative movement is at a speed of one revolution per year. The week mechanism is driven from a second gudgeon point.
