Patent number: 8605553Abstract: The annual calendar device carries a date ring (1) and a drive wheel (5) for said ring. The drive wheel (5) carries a mechanism (10) including a first finger (6) driving the ring (1) through one step each day and a second finger (7) which is inserted, at the end of the months of less than thirty-one days, into the trajectory of the teeth (4) of the ring (1) to move said ring forward one additional step. The second finger (7) is inserted into said trajectory by a kinematic chain (9) controlled by a toothing (8) carried by the ring (1).Type: GrantFiled: January 12, 2012Date of Patent: December 10, 2013Assignee: ETA SA Manufacture Horlogère SuisseInventors: Julien Chaignat, Stefan Rombach

Patent number: 8040759Abstract: Device that assists in maintaining the position of a date indicator disc (2; 3) for a timepiece, the position of the date indicator disc (2; 3) being indexed by a jumper spring (50; 50?), said device being characterized in that it includes a locking member (52; 52?) which, outside the date indication correction phases, keeps the jumper spring (50; 50?) locked, said locking member (52; 52?) moving away in the date indication correction phase to release the jumper spring (50; 50?).Type: GrantFiled: October 23, 2009Date of Patent: October 18, 2011Assignee: ETA SA Manufacture Horlogère SuisseInventor: Julien Chaignat

Patent number: 7957226Abstract: A correction device for a timepiece display mechanism, which includes a display member fitted with a toothing of pitch P, includes a pinion provided with a toothing of pitch p, mounted on a winding stem so as to occupy at least one display correcting position A, and a correction wheel mounted between the pinion and the display member. The correction wheel includes a first toothing defined by pitch P, a head diameter D, and a foot diameter d1, formed of teeth including a tip extending substantially angularly, and the tip is cut so as to form a second discontinuous toothing that is coplanar and concentric to the first toothing, defined by pitch p less than the pitch P of the first toothing, a head diameter D equal to the head diameter of the first toothing, and a foot diameter d2 greater than the foot diameter d1 of the first toothing.Type: GrantFiled: March 27, 2008Date of Patent: June 7, 2011Assignee: ETA SA Manufacture Horlogère SuisseInventors: Julien Chaignat, Marco Bettelini
