The present invention relates to an electronic timepiece allowing the display of at least one first time related data item (H ) conventionally based on the Hour-Minute-Second system, and at least one second time related data item (H ) based on a decimal system in which the time is divided at least into thousandths of a day. For this purpose the timepiece according to the present invention includes generating means ( ) which, from auxiliary control pulses (I ) originating from the time base ( ), allow second control pulses (I ) to be supplied allowing said second time related data item (H ) to be formed and displayed.

The present invention concerns a device for securing a back cover ( ) to a middle part ( ) of a watchcase ( ), the back cover ( ) having a screw thread ( ) on its outer periphery, the device being characterized in that it includes an intermediate element ( ) including a resilient blocking element ( ) and a metal element ( ) concentric to the resilient blocking element ( ), this intermediate assembly being forcibly driven into the lower part of the middle part ( ) of the watch ( ), and the back cover ( ) being screwed onto the metal element ( ) so that, when the back cover ( ) is completely screwed onto the metal element ( ), the metal element ( ) can be pivoted by sliding on the resilient blocking element ( ) to a stop point from which the resilient blocking element ( ) can in turn pivot by sliding on the middle part ( ) of the watch ( ), allowing the alignment of the back cover ( ) to be adjusted with respect to the vertical 12 o'clock-6 o'clock axis of the watch ( ).

The electronic watch movement components ( ) of the watch are mounted on a flexible printed circuit film ( ), which is then incorporated in the wristband ( ) by overmoulding of an insulating elastomeric material. External elements in the form of cases ( ) are mounted in a sealed manner on the wristband to protect said components and to cover at least a display unit ( ) and an electric power source ( ). Decorative elements ( ) similar to the cases are distributed along the wristband to imitate links. Such a wristwatch may be manufactured at a low cost.

The assembly according to the invention comprises a hard plastic watch case ( ), having on its middle part one or more sealed push buttons ( ) made in an inexpensive manner. Each push button ( ) comprises a hard plastic stem ( ), for example the same material as the case, and an elastomer flexible head ( ) which is over molded onto an external surface ( ) of the case. The case and the push buttons may be manufactured by injecting two materials in a single mold. The invention applies to electronic watches and to mechanical watches.
