Electronic wrist or pocket watch comprising a rotary crown

An electronic wrist or pocket watch comprising:

• a case;
• a display means for displaying a plurality of symbols;
• a processing means in signal communication with the display means, the processing means being configured for controlling said display means in a manner such that the display means will display a screen where a first symbol is selected from among a plurality of available symbols, the plurality of available symbols being displayed at a plurality of spaced apart locations on the screen, one of the plurality of spaced apart locations being a fixed, reserved location where the selected first symbol is disposed;
• a rotary crown associated with the case;
• a transmission shaft coupled to the rotary crown;
• and
• a motion detection means configured for detecting at least a rotary motion of said rotary crown,
• wherein:
• said motion detection means is in signal communication with the processing means, and
• said processing means is also configured for controlling the display means in a manner such that, when the rotary crown is turned, each of the plurality of available symbols are moved to a different one of the plurality of spaced apart locations so that a second symbol, different from the first symbol, will be selected from among the plurality of available symbols and will be disposed at the fixed, reserved location,
• the rotary crown is also configured in a manner such that the rotary crown can be moved along an axis of rotation of said rotary crown so that the rotary crown can be extracted from the case,
• the motion detection means comprises a translation sensor in signal communication with the processing means, the translation sensor being configured for detecting extraction of the rotary crown from the case,
• the translation sensor comprises a piezoelectric element coupled to said transmission shaft in such a manner that when the rotary crown is extracted from the case, said piezoelectric element is deformed, thereby generating an electric current that is detected by the processing means, and
• when any one of the plurality of available symbols that are at the spaced apart locations on the screen is selected by rotation of the rotary crown, the selected symbol is always located at the fixed, reserved location.
