Abstract
Abstract The day dial of a calendar timepiece is provided with a plurality of language designations for each day. The jumper lever operating in in conjunction with the day star wheel is provided with two teeth have a circular pitch one half the circular pitch of the teeth on the day star wheel. A manual selection device is provided to shift the relative position of the jumper lever teeth relative to the teeth on the day star wheel thereby shifting the day dial to display a selected language.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
111 words
In a display mechanism of a day calendar timepiece comprising a day feed gear, a day dial driving wheel, and a day star wheel mechanically connected one after another, a jumper lever resiliently cooperating with said star wheel and a day calendar dial fixedly mounted on said star wheel, said star wheel being formed on its periphery with seven teeth, the improvements comprising n - different day calendar representations, n being preferably the number of different languages employed, and n suCcessive jumper projections formed on said jumper lever for cooperation with said star wheel for positioning said star wheel at n - different positions for each of 7 day calendar displays.
Claim 2
Dependent Claim
111 words
In a display mechanism of a day calendar timepiece comprising a day feed gear, a day dial driving wheel, and a day star wheel mechanically connected one after another, a jumper lever resiliently cooperating with said star wheel and a day calendar dial fixedly mounted on said star wheel, said star wheel being formed on its periphery with seven teeth, the improvements comprising n - different day calendar representations, n being preferably the number of different languages employed, and n suCcessive jumper projections formed on said jumper lever for cooperation with said star wheel for positioning said star wheel at n - different positions for each of 7 day calendar displays.
Claim 3
Dependent Claim
85 words
The mechanism as set forth in claim 1, further comprising a control push button slidably mounted on the conventional plate of a timepiece movement, a lever pivotably mounted on said plate and arranged to cooperate with said button and said driving wheel, and a return spring acting upon said lever, for converting the calendar display from one already selected one to another newly selected one by advancing said star wheel relative to said jumper a fraction of the star wheel tooth pitch equal to 1/n.
Claim 4
Dependent Claim
25 words
The mechanism as claimed in claim 1, characterized by that said day dial driving wheel is formed with seven times n teeth on its periphery.
Claim 5
Dependent Claim
26 words
The mechanism as claimed in claim 3, characterized by that said dial feed gear is provided with a pin adapted for engagement with said driving wheel.
