An electronic timepiece improves operability when manually adjusting the time. The electronic timepiece includes: a time display configured to indicate the time; a rotatable crown that can be pulled out to multiple stop positions, including a first position and a second position; a stop position detector configured to detect the stop position of the crown; an operation detector configured to detect an operation rotating the crown; and a time setter configured to change the time displayed by the time display according to an adjustment amount that differs according to the stop position at each detected operation when the stop position is the first position or the second position and the operating detector detects the operation.

A push-piece winding button control device is for a portable object of small dimensions. This device includes a pivoting control stem axially movable between at least a transitory first position and a stable second position. The device further includes a position indexing plate arranged to be integral in translation with the control stem, while keeping the same orientation relative to the frame. The device also includes a cam follower arranged to cooperate with a longitudinal cam path formed in the position indexing plate. The cam path includes a recess defining the stable position of the control stem, and a ramp-shaped profile portion which rises from the recess towards the transitory position.

The invention relates to a correction device for a timepiece, comprising a differential gear having a first inlet, a second inlet and an outlet, wherein: the first inlet is arranged to be driven by a timepiece movement; the second inlet is kinematically linked with a corrector gear extending from a control member and comprising a clutch for establishing and interrupting the kinematic link between said control member and said second inlet; the outlet is arranged to drive a display device of said timepiece movement, the angular position of said outlet being defined on the basis of the angular position of said first inlet as well as on that of said second inlet, wherein said correction device further comprises a memory cam desmodromically linked with said second inlet, in that said memory cam experiences a return force provided by a resilient member tending to maintain said memory cam in at least one predetermined angular position when said kinematic link between said control member and said second inlet is interrupted, said resilient member also being arranged to allow a rotation of said second inlet under the control of said control member when said kinematic link is established during the use of the correction device, and in that said correction device is arranged so that the incidence of the rotation of the second inlet during a correction on the angular position of the outlet is removed when said memory cam is located in said at least one predetermined angular position.
