Disclosed is a mechanical timepiece movement including a chronograph mechanism arranged to be capable of carrying out at least one countdown of a predetermined time interval, including a display arranged to display at least the time remaining until the end of the countdown of the predetermined time interval, at least one member for controlling the start of the countdown, and a striking-mechanism. The striking-mechanism is arranged to start striking at a specified time before the end of the countdown and to stop striking at the end of the countdown of the predetermined time interval.

The invention relates to a timepiece movement comprising at least first and second functions implementing the display of at least first and second pieces of information. According to the invention, the movement has a selection member comprising an actuator, at least one lever configured to take at least first and second positions, respectively corresponding to the first and second functions, and respectively corresponding to the creation of first and second kinematic connections, and a cam cooperating with the actuator and the at least one lever so as to create the first and second kinematic connections.

An adjustable timer teaches time in a simple manner to those having difficulty understanding the concept of time. The timer displays remaining and elapsed time. The timer may be set to rotate a shaft at different speeds. A colored disk is attached to the shaft. Boards having faces with different numerical indicia reside in a cavity and may be interchanged by a user. The exposed board face corresponds to the setting of the timer such that one full rotation of the shaft and disk corresponds to the numerical indicia of the exposed board face.

The present invention relates to a timepiece comprising a watch movement including a complication of the chronograph or countdown type, a fixed body (10) and a display (20) with moiré effect for displaying a time information associated with the chronograph or the countdown. The display comprises a mobile disc (22) with an indicator (24) of the time information. The mobile disc (22) is, on the one hand, connected to an axis (23) in engagement with the watch movement and, on the other hand, arranged to rotate above or below the fixed body (10). One of the mobile disc (22) and the fixed body (10) comprises a plurality of apertures (26) arranged over 360°. The other of the mobile disc (22) and the fixed body (10) comprises a marking with a repetition of patterns including a first set of patterns having a first visual appearance (27) and a second set of patterns having a second visual appearance (28). The patterns having the first visual appearance are arranged alternately with the patterns having the second visual appearance over 360°. The plurality of apertures (26) are separated from each other by a plurality of portions (30) intended to progressively mask the patterns of the marking in order to produce the moiré effect when the mobile disc (22) is rotated.
