Abstract: The invention relates to a wristwatch with a clock generator assembly. The clock generator assembly includes a first clock generator, a pulse counter, and an output device. The first clock generator includes a piezoelectric oscillating crystal and is configured to generate a clock signal. The pulse counter is configured to count the clock signal of the first clock generator, wherein the output device is configured to output a useful signal if a count value of the counted clock signal of the first clock generator is equal to a predetermined count value.

Abstract: The invention relates to a timepiece, in particular a wristwatch, comprising an electro-optical converter device with at least one electro-optical converter, an opto-electric converter device, a first signal path which leads into the opto-electric converter device via a first waveguide, a second signal path which leads into the opto-electric converter device directly or via a second waveguide, a control device, and a useful-signal generating device. The first signal path and the second signal path are designed such that the propagation time of the first clocked light signal in the first signal path and the propagation time of the second clocked light signal in the second signal path differ from each other.

Abstract: A watch glass includes a first glass, a second glass and a decorative element. The second glass is connected to the first glass via a connecting intermediate layer. The decorative element is inserted in a setting, which is arranged in a watch glass recess. The watch glass recess is formed by a first recess in the first glass and a second recess in the second glass. Here, a space of the watch glass recess is defined by the first glass, the second glass and the setting. The space is filled with connecting material of the connecting intermediate layer, so that the setting is connected via the connecting material to the first class and the second glass.

Abstract: A watch glass includes a first glass, second glass and a decorative element, in particular a gemstone. Here, the first glass and the second glass are connected to one another via a connecting intermediate layer. The first glass includes a continuous recess. The decorative element includes a base region, which is arranged settingless in the recess of the first glass and in direct contact with the connecting intermediate layer. Further, a watch can include such a watch glass.

Abstract: Provided is a watch glass including a support glass having at least one recess, a cover glass, at least one gemstone which is at least in part disposed in the recess, and a connecting intermediate layer by way of which the cover glass and the support glass are connected to one another. A region of an upper part of the gemstone is in direct contact with the intermediate layer.

Abstract: The invention relates to a gemstone arrangement, that comprises a first gemstone element, a second gemstone element, which is connected to the first gemstone element, and at least one decorative element, which is arranged between the first gemstone element and the second gemstone element. Furthermore, the invention relates to a method for producing the gemstone arrangement. A further aspect of the invention relates to a jewel with a gemstone arrangement.
