Patent number: 4748603Abstract: The watch comprises a conventional timepiece movement driving the hours-hands, the minutes-hands and the seconds-hands, to which is added a chronograph module the frame of which, having the shape of a bell, covers the movement of the timepiece. The chronograph is autonomous, i.e. its indicators are not driven by the basis movement but by electric motors situated around the central movement, fed by a battery and piloted by a quartz oscillator, the frequency divisions being effected by an integrated circuit. The printed circuit associated with this whole comprises an annular plate surrounding the timepiece movement. An intermediary plate ensures the connection between the timepiece movement and the chronograph module. The transformation of a conventional timepiece movement into a chronograph watch is thus very easy, the chronograph module being able to be applied to very different timepiece movements, only the intermediary plate having to be different.Type: GrantFiled: May 28, 1987Date of Patent: May 31, 1988Assignee: Conseilray S.A.Inventors: Claude Ray, Michiel Groothuis
