Embodiment Construction

[0021] The invention stems from the general inventive idea of ​​rigidly engaging the hour wheel with the additional wheel by means of a connecting pinion during all operating phases of a time-zone timepiece except for setting the time in zone time. Thus, the torque transmission from the motion work to the attachment during the working phase and the time setting phase passes through the hour wheel, the connecting pinion and the additional wheel. The transmission of force between the hour wheel and the additional wheel is thus deviated (the original path) through the connecting pinion, except for the time at the set zone time - in which case the connecting pinion is disengaged - so that the time The limited torque mechanism engaging the wheel and the additional wheel no longer operates.

[0022] The present invention will be described below in conjunction with the additional device of the instant-jump calendar mechanism type. Of course this example is for illustration only and ...

Abstract

The invention discloses a time zone clock including an hour hand (6), which can move forward or backward in steps of one hour through a manual time setting handle (28) without affecting the minute display. The hour hand (6) is installed on an hour wheel tube (4), an hour wheel (2) driven by a hand movement mechanism (10) is adjusted to freely pivot around the hour wheel tube, and an hour wheel (2) is fixed on the tube (4) The additional wheel (12) on the watch drives an additional device, and the hour wheel (2) is connected to the additional wheel (12) through a limited torque mechanism (16). The characteristic of the clock is that, in addition to correcting the time zone time, In addition, the hour wheel (2) and the additional wheel (12) are further rigidly connected through a second connecting mechanism.

Description

technical field [0001] The present invention relates to a time zone clock whose hour hand can be moved forward or backward in steps of one hour by a manual time setting handle without affecting the display of minutes. technical background [0002] Timepieces of the above type are very useful when a traveler travels from one time zone to another and has to adjust his watch to the new time. Because the time difference between the new time and the old time is a full hour in one direction or the other, it is beneficial for the person wearing the watch to have a means of instantly moving the hour hand forward or back a full hour without affecting the minute display of. [0003] In order to solve the problems posed above, CH Patent No. 388855 of Ruch and CH Patent No. 685965 of Ulysse Nardin are known. [0004] The Ruch patent relates to a timepiece comprising a local time indicating member, a time zone time indicating disc rotating around an hour wheel tube, and a bridge and st...
