摘要:
A watchcase coupling structure including an outer rim and coupling pins adapted to couple a front cap and a rear cap, wherein the coupling pins may be mounted in the outer rim and the rear cap without relying upon a threading-in method. Each of these coupling pins may take various configurations. Specifically, it may be the one which has an eccentricity by an amount corresponding to a margin required to adjust the force with which the packing interposed between the front cap and the rear cap is clamped or the one which is provided on its head with a slant portion to facilitate the operation of mounting. Furthermore, it may be the one which is provided on the front end with a notch or the like or the one which has a flange to prevent the pin from falling off. To employ the pin having the flange, the outer rim is provided with a keyhole-shaped notch and the circular head of the pin is symmetrically cut away to present a pair of parallel surfaces so that the pin head may be soothly guided along said keyhole-shaped notch.

An electronic device includes a compound designed to raise a surface tension of a water-based solution. The electronic device may include a vent feature to allow air to pass through the vent feature such that the air reaches a component in the electronic device. The vent feature may include a first vent structure and a second vent structure, both of which combine to confine the compound. When the water-based solution passes through an electronic device opening, the water-based solution may reach the first vent structure. If a surface tension is sufficiently low, the water-based solution may pass through the first vent structure. However, the water-based solution may then reach the compound causing the compound to dissociate, forming form positive and negative ions that attract molecules of the water-based solution. Then, the water-based solution surface tension increases and does not pass through the first vent structure or the second vent structure.

The invention relates to a timepiece comprising: a casing (10) with a bottom (12), a middle (14) and a control body (16) mounted movably in relation to the middle (14), a movement (18) housed in the casing (14), a glass (26) closing the casing, a dial (28) arranged between the movement (18) and the glass (26), said dial (28) comprising two polarised lenses (28a, 28b), at least one of which is mounted on a mobile frame (30), such that said polarised lenses (28a, 28b) can assume a first state wherein elements arranged behind the dial (28) in relation to the glass (26) are visible from the side of the glass (26) and a second state wherein said elements are hidden. A kinematic connection is arranged between the control body (16) and the mobile frame (30), said kinematic connection comprising a first toothing secured to the control body, a second toothing secured to the mobile frame and arranged in a different plane from that of the first toothing, and a setting-wheel train kinematically connecting the first toothing and the second toothing. The setting-wheel train is pivoted on the middle (14) and comprises at least two moving parts arranged in the same plane parallel to the plane defined by the movement (18), and at least two moving parts that are interconnected by a shaft pivoted on the middle (14) and orthogonal thereto.

The wristwatch includes a bracelet or strap, a plastic case including a case middle-bezel, a watch crystal, a back cover and two pairs of horns to which the two ends of the bracelet or strap are respectively 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 is characterized in that it 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.

The invention concerns a device for securing a back cover on a middle part of a watchcase, characterized in that it includes an intermediate element to which the back cover is connected, said intermediate element being screwed onto the middle part of the watch, means being provided to allow the back cover to drive the intermediate element in rotation until the latter reaches a locked position on the middle part, the back cover also being able to be pivoted relative to the intermediate element without the latter being unscrewed for alignment with the 12 o'clock-6 o'clock axis of the watch.
摘要:
The aim of the present invention is to provide a device whereby various wristwatch movements can be fitted to a single strap, meaning that the watch can be replaced or reversed quickly without opening the strap or case. This aim is achieved by means of a device whereby an object such as a watch case is rendered reversible and interchangeable in a supporting element that is open on one side so that the reversible and interchangeable object can be inserted or withdrawn through said side opening, characterised in that said side opening is sealed by a portion of the reversible and interchangeable object that fits snugly onto the open side of the supporting element, thereby locking same. The device comprises retaining means for retaining the reversible and interchangeable object within the supporting element. It should be noted that in one embodiment of the device, there is no strap (100) and a clip (300) is inserted into portions (202, 203) of the supporting element (200) so that the assembly can be used as an adornment.

This invention relates to a bayonet-type coupling device of the back-cover and the middle of a waterproof shaped watch-case, in which said middle presents a hollow comprising an annular groove in its internal wall and said back-cover comprises a cylindrical or prismatic annular wall provided with at least two ledges, and in which the sizes of said annular wall and of said hollow are such that, for at least an angular position of the back-cover with regard to the middle, they are free, the annular wall of the back-cover being placed within the hollow of the middle, and that, for at least another angular position, they are coupled by engagement of at least a part of the ledges in the annular groove, characterized by the fact that said angular coupling position is defined by the contact of a part of the external surface of the annular wall of the back-cover with the internal surface of the hollow, both these surfaces having the same shape and the same sizes, so that the external surfaces of the middle and of the back-cover are in coincidence. The external surface of the annular wall of the back-cover comprises at least an edge, constituting a locking strong point, cooperating with the internal surface of the hollow in order to lock the back-cover and the middle in their coupling angular position. There is a watertight joint between the middle and the back-cover that encircles the annular wall of said back-cover.
