摘要：
The invention concerns a mechanism (100) for displaying, on demand, the time in a time zone, on the hands of a timepiece.It is characterized in that it includes: two memory wheels (30), each including a heart-piece (40) that pivots relative to a toothed wheel (31) between indexing positions (34) thereon, with which it cooperates via a finger-piece (41) radially returned to said positions by a spring (43), support means (50), which, between two actions by the user, connectably cooperates with a support surface (45) of a memory wheel (30) and is then disconnected from a support surface (45) of the other memory wheel (30), a differential gear (12) with a first input formed by a motion work wheel set, a second input formed by a crown (12A) of said differential gear (12) with which each memory wheel (30) meshes, and an output consisting of an hour hand (25). The invention concerns a timepiece incorporating a mechanism (100) of this type.
