Patent number: 11526131Abstract: A device (1), and timepiece having the device, for displaying a succession of periodic events which form an annual cycle, including a periodic events indicator member (2) and a mechanism (4) for managing a duration during which the periodic events are displayed by the periodic events indicator member (2). The management mechanism includes a cam (8) for managing a duration during which the periodic events are displayed, which cam is arranged such that it controls the change from the indication of a periodic event to the indication of a subsequent periodic event by the periodic events indicator member, a periodic driver (10) for driving the management cam (8) and a member (6) disposed between the management cam and the periodic events indicator member and arranged such that it drives the periodic events indicator member (2) during a change in event. The device displays the periods of the zodiac.Type: GrantFiled: November 12, 2019Date of Patent: December 13, 2022Assignee: ETA SA MANUFACTURE HORLOGERE SUISSEInventor: Stephane Bachmann

Publication number: 20220137558Abstract: A mechanical horological movement (1) including at least one barrel system (2) for driving a set of wheels and power reserve detector. The detector (10) includes a control wheel (3) disposed opposite the cage of the barrel system (2) and is rotated by a complementary wheel (8) at the differential output to determine a power reserve level. An aperture (13) has a first end (21) to define a complete charge of the barrel system and a second end (22) to define a complete discharge. A lever (4) is rotatably mounted about a lever axis parallel to the axis of rotation of the control wheel. A contact element (5) disposed in the aperture contacts the second end during a zero power reserve indication. A portion of the lever contacts a component of the movement to stop its operation when power reserve indication is at zero.Type: ApplicationFiled: July 21, 2021Publication date: May 5, 2022Applicant: ETA SA MANUFACTURE HORLOGÈRE SUISSEInventors: Stephane BACHMANN, Julien SAGLINI, Laurent KLINGER, Baptist WYSSBROD
