A roller jumping timepiece display mechanism, each display of which includes a roller and/or a combined roller including two rollers internal to each other, held in the rest position by first elastic return means, at least one display is movable in rotation controlled by the movement of at least one lever whose fall is controlled or prohibited by at least one cam driven by a movement, and at least one trigger or correction lever is arranged to bearingly cooperate simultaneously with two cams towards which it is returned by second elastic return means.

Roller jumping timepiece display mechanism

A corrector () for a function indicator () for a movement () including: a first control mechanism () for a first function, in a let down () or wound () position, a second control mechanism () for a second function, in a let down position () or release control position () followed by a return to the preceding position, and a display indicator () for a third function. First mobile part () driven by the first control mechanism () occupies a letting down ()/winding () position, when the mechanism occupies the let down ()/wound () position. Second mobile part () actuating the indicator () is driven by the second control mechanism () changing into the control position () when the first mobile part () is in a winding position () and cooperates with this latter in the letting down position (), under the action of return mechanism ().

Quick corrector for a time related magnitude indicator for a timepiece

This timepiece comprises an indicator dial (), a days-of-the-month mechanism () comprising a days-of-the-month mobile () and a stepper drive member () for driving the days-of-the-month mobile (), a months mobile () coaxial with the days-of-the-month mobile placed beneath said dial () and connected to the days-of-the-month mobile () by stepper drive means () formed so that the months mobile () turns through an angle of 30&#xb0; each month. The dial () has twelve windows () that are angularly equidistant and the months mobile () supports a distinctive zone () of which the trajectory passes through said windows () and of which the maximum angular extent is 30&#xb0; and the minimum angular extent corresponds to that of said windows ().

Timepiece

This timekeeper comprises a first timer (), means () for connecting it selectively to the train of the timekeeper (T), a second timer (), a synchronous coupling between the first () and second () timers, and fly-back means () for said timers (). An auxiliary motive source (') is in a driving relationship with the second timer () and a one-way coupling () is situated between the first () and second () timers to regulate the speed of movement of the latter at a predetermined ratio with the speed of movement of the first timer () while allowing one-way relative movement of the first timer () relative to the second () when the latter is in the stop position and one-way relative movement in the opposite sense of the second timer () when the first timer () is in the stop position.
