Abstract:
A timepiece including a clockwork movement, provided with an analogue display, including:at least a first and a second coaxial rotating display indicator attached respectively to corresponding coaxial pipes mounted co-axially, a first angular position indicating moving part formed by a first of said pipes carrying a first plate perpendicular to its axis, also associated with said first moving part, a first magnetic angular position sensor for said first moving part and consequently of said first display indicator, said first plate having at least one discontinuity of material capable of being detected by said first sensor, when said first moving part rotates with respect to said first sensor, to provide a first measurement signal representative of an angular position of said first display indicator; at least a second angular position indicating moving part for said second display indicator, said second moving part being mounted at a distance from said first moving part and in a meshing relationship with a second of said pipes, said second moving part carrying at least a second plate perpendicular to its axis; and also associated with said second moving part, a second magnetic sensor of the angular position thereof and consequently of the second display indicator, said second plate having at least one discontinuity of material capable of being detected by said second sensor when said second moving part rotates with respect to said second sensor, to provide a second measurement signal representative of an angular position of said second display indicator.
