An electronic watch includes memory that stores a reference time and a time difference relative to the reference time, a timekeeper that clocks the reference time, a time display unit that includes an hour hand displaying a display time based on the reference time and the time difference, a calendar display unit that displays a date based on the reference time and the time difference, an operation device that includes a crown or a button, and a controller that, in a set time-difference setting range, corrects the time difference at a regular interval for each of operations of the operation device, and updates the hour hand and the date in accordance with the corrected time difference.

A timepiece movement includes a date indicator for date display, a date indicator driving wheel for advancing the date indicator, a lunar age indicator for lunar age display, and a lunar age indicator driving wheel for rotating the lunar age indicator. The date indicator and the lunar age indicator are coaxially disposed, and the date indicator driving wheel and the lunar age indicator driving wheel are coaxially disposed.

Disclosed is a clockwork with pointers or with a pointer module driven by a mechanical driving gear, wherein the clockwork is a hybrid clockwork that in addition to the mechanical driving gear, also at least includes an additional driving gear with a motor and an electric or electronic controller that is internal and which is equipped to be able to drive and/or adjust the pointers or the pointer module in parallel or in series with the mechanical driving gear.

A mirror imaged timepiece that is to be adorned (worn) on the human body, such that when viewed through a reflecting mirror, will be viewed and observed in its correct proper perspective. This will allow the creation of timepieces to be worn on new areas of the body where previously it was not feasible, because the wearer would have had difficulty viewing these timepieces in its correct perspective on these certain difficult to view areas of the human body. Timepieces such as broach timepieces, pendant timepieces, earring timepieces, choker timepieces, headband timepieces, upper arm timepieces, tie clip timepieces, lapel pin timepieces, and etc. were not feasible because the wearer would not be able to view them in its proper perspective without difficulty. The present invention allows the creation of timepieces that can be worn on new areas of the human body where they were not feasible before, because now with the present invention the wearer will be able to view the Mirror Image Timepiece easily, in its correct proper perspective, through either a hand-held mirror, a wall positioned mirror, or any other reflective surface, when adorned on these difficult to view areas of the human body.

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.

Disclosed is a timepiece including a display mechanism arranged to control the movements of a display organ with respect to an indication scale including different indications having at least two different widths and being separated from one another by corresponding separation spaces, the timepiece being characterized by the fact that the separation spaces all have substantially one and the same width.
