A calendar mobile (10) indicating time information or information derived from the time, comprising at least one first obstacle element (1a, 2a, 3a) intended to receive a driving contact action driving the calendar mobile and/or intended to transmit a driving contact action from the calendar mobile, the first obstacle element being made of titanium or of titanium alloy, the mobile being a disk or the mobile having substantially the shape of a disk or the mobile having substantially the shape of a disk ring.

A timepiece display device including a first display element and a second display element superimposed above a fixed part including a main bearing surface, this second display element is subjected to opposing forces exerted, on the one hand by lower return means which tend to bring the second display element closer to the first display element, and, on the other hand, by upper return mechanism which tends to move the second display element away from the first display element without contact between them or else by mechanical spacing device which includes a bearing surface providing a stop bearing function on a stop surface of the second display element, to limit the travel from the second display element to the first display element.

Disclosed is a display mechanism for a timepiece movement including a first display wheel and a second display wheel, which are arranged to be coplanar, characterised in that the first and second display wheels are further arranged to be pivoted with respect to each other by way of at least one ball bearing.

A display device (1) designed to be integrated into a timepiece, such as a watch, the display device (1) including a first lenticular grating (11) and a first supporting element including a pattern arranged so that it can be seen through the first lenticular grating, the device being remarkable in that it includes a second supporting element including a second lenticular grating (12), the second supporting element extending above the first supporting element and being arranged so that the pattern can be seen through both the first and second lenticular gratings (12), one of the first or second supporting element being a supporting element rotating around an axis perpendicular to the plane P in which the pattern extends.

A device applied to a mechanical timepiece movement whether it be hand-wound or automatically wound for measuring two time zones using two twelve-hour hands in which a three-position crown is used to wind, jump the date disc in one-day increments, jump the second time zone hour hand forwards or backwards in one-hour increments, and set the time. In particular, the invention proposes a device for synchronizing the time keeping between both twelve-hour hands and allowing the second time zone hour hand to be independently jumped in one-hour increments without affecting the time measured on the other hands from a single time setting device.
