Abstract: The present invention provides thermochromic liquid crystal inks and coatings. The ink and coating compositions comprise one or more non-encapsulated cholesteryl materials, one or more resins that are not cholesteryl materials, and one or more solvents. In certain embodiments, a thermochromic effect is observed at about body temperature.

Abstract: The present invention provides a fully integrated digital workflow for the designing and production of packaging. A designer creates a package design with a special effect ink digitally, using a computer connected to a color database and a special effect ink database. Advantageously, the present workflow minimizes the complexity of the workflow by using transparent color layers printed over plain special effect additive ink layers to develop the special effect inks to be used on press. The present workflow advantageously can also be used to assess match of polychromatic inks.

Abstract: A watch, in particular a dive watch, having a movement (16) which is arranged in a watch case (12) and can be used to drive an hour hand (3) via an hour tube and a minute hand (4) via a minute tube in a fashion sweeping over a dial (1). Also present is a pressure detecting device for detecting the ambient pressure outside the watch case (12) and a display for representing the detected pressure values. There is arranged in the watch case (12) a mechanical pressure transducer to which the ambient pressure outside the watch case (12) can be applied and by means of which a mechanical depth measurement mechanism (17) of a mechanical display can be driven.

Abstract: A display setting arrangement for a timepiece, having a 12-hour display, on which, driven in a rotatable manner by a basic mechanism with two revolutions every 24 hours, the hours can be displayed. There is also a second hour display, which can be driven in a rotatable manner likewise by the basic mechanism. By means of a correction device, the 12-hour display can be adjusted manually relative to the second hour display. The second hour display is a 24-hour display and can be driven in a rotatable manner, in a direct gear train, by the basic mechanism of the time piece with one revolution every twenty-four hours. Via a force-fit connection, a 12-hour gear train can be driven in a rotatable manner, for the purpose of driving the 12-hour display, by a direct-gear-train wheel which is driven with one revolution every twelve hours.

Abstract: A watch has an hour wheel (17) which can be driven in rotation around an axis of rotation (10) by a drive, and has a rotatable universal-time hour wheel (13) arranged coaxially thereto. These two hour wheels are connected to each other by a spring-loaded detent connection. The universal-time hour wheel (13) is rotatably settable stepwise relative to the hour wheel (17) by a setting element. It overcomes the spring force of the detent connection, in which connection the setting element can be coupled to the universal-time hour wheel (13) for setting the latter and can be decoupled again after the setting. The hour wheel (17) is connected to an hour hand (2), and a universal-time hour hand (3) is connected to a universal-time hour wheel (13), by which means the times of two different time zones can be indicated on a stationary dial face.

Abstract: A watch having a crown for setting the motion work and having a device, which can be driven by the hour wheel of the movement of the watch, for the automatic display of the months and the days of the month in accordance with the Gregorian calendar. In this connection, the display of the day of the month can be driven by a date wheel 13 and the display of the month by a month wheel 22 of the device. A year wheel of a year display and a decade wheel 26 of a decade display and possibly a century drive of a century display form together with the wheelwork of the month display and the day of the month display a closed coupling-less calendar wheelwork train whose date wheel 13 can be set by a correction device.
