<p>CORRECTION DEVICE FOR TIMEPIECE DISPLAY MECHANISM AND WHEEL FITTED THERETO The invention concerns a correction device (10) for a timepiece display mechanism of the type including a display member (12) fitted with a toothing (16) of pitch P, the correction device (10) including a pinion (26) provided with a toothing (30) of pitch p, mounted on a winding stem (24) so as to occupy at least one display correcting position A, and a correction wheel (38) mounted between the pinion (26) and the display member (12). The correction wheel (38) includes a first toothing (40) defined by a pitch P, a head diameter D, and a foot diameter dl, formed of teeth (42) including a tip (44) extending substantially angularly, and the tip (44) is cut so as to form a second discontinuous toothing (46) that is coplanar and concentric to said first toothing (40), defined by a pitch p less than the pitch P of the first toothing (40), a head diameter D equal to the head diameter of the first toothing (40), and a foot diameter d2 greater than the foot diameter dl of the first toothing (40).</p> |
