Abstract: Provided is a watch glass configured to be disposed on a watch dial with indications. This watch dial comprises at least one indication, a first chamber configured to let a first mobile element circulate, a second chamber configured to comprise a second mobile element and a separation wall separating the chambers and large enough to obtain from the indications of the dial an enlarged image.

Abstract: A skeleton watch includes a case middle which defines an interior space, a crystal and a back cover fixed to the case middle on either side of the middle to enclose the interior space, and a movement. The movement includes an openworked frame having a front face and a back face, the frame including an outer perimeter formed by two side positions, a top bar that connects between upper ends of the side posts, and a lower platform connected to lower ends of the side posts. The frame includes a central island positioned within the outer perimeter. The movement also includes a minute hand and an hour hand mounted on a central arbor integral with the frame. The movement also includes a motor having an electromagnet that extends outside of the outer perimeter of the frame in a radial direction from the central arbor.

Abstract: The invention relates to a skeleton watch including: a case middle; a movement including: a frame; time display means; a reduction mechanism meshed with the time display means; a motor including: an electromagnet; a stator; a rotor bearing a pinion meshed with the reduction mechanism; an electronic circuit including: a piezoelectric quartz; a control circuit connected to the quartz and to the stator by means of electrical conductors; an additional plate which carries the electronic circuit, said additional plate being distinct from the back cover and fixed to the frame.

Abstract: A wristwatch includes a bracelet or strap, a plastic case, a watch crystal, a back cover and pairs of horns to which the ends of the bracelet or strap are attached. It also includes a top half shell made of metal which covers the top of the case and a portion of the case middle and which has an opening revealing the crystal. It further includes a crown or a control push-button protruding from the case middle. The wristwatch further includes a bottom half shell covering the back cover and a portion of the case middle. The top half shell and the bottom half shell respectively have two, substantially symmetrical, peripheral rims which extend facing each other, the crown or the control push-button being located in an elongated space extending between the rims of the two half shells. The elongated space also reveals a portion of the case middle.

Abstract: The timepiece includes a stationary outer case (1) in which a pivoting inner case (10) is hinged in an inclined position via the action of a spring. The locking/unlocking mechanism is characterized in that it is formed by a mobile element of the external part that can be manipulated in the plane of the timepiece such as a rotating bezel (20) of the inner case (10) including a lug (22) that is engaged in a groove (2) of the outer case (1).
