Timepiece

Abstract

A timepiece, comprising indicating means driven by a movement for indicating the hours and minutes and also the date, characterized in that there are disposed around the said indicating means a first annular surface carrying indications of the dates of a month of 31 days, and a second annular surface concentric with the first one and carrying indications of the consecutive days of the week of at least five consecutive weeks, at least one of said annular surfaces being disposed on a turning ring which can be rotated manually for radially aligning the indications of the dates and the indications of the days of the week to form a complete calendar of a month.

What is claimed is: 
     
       1. A timepiece, comprising indicating means driven by a movement, said indicating means including hands for indicating the hours and minutes and a date ring for indicating the date, characterized in that there are disposed around the said indicating means within the casing of the timepiece a first annular surface carrying indications of the dates of a month of 31 days, a second annular surface concentric with the first one and carrying indications of the consecutive days of the week of at least five consecutive weeks, at least one of said annular surfaces being stationary and having window formed therein, the other of said annular surfaces being disposed on a turning ring which can be rotated manually for radially aligning the indications of the dates and the indications of the days of the week, and a third annular surface carrying indications of the 12 months of the year, said third annular surface being disposed on a turning ring which can be manually rotated for presenting one of the twelve month indications in the window of said at least one stationary annular surface, said surfaces cooperating to form a complete calender of a month. 
     
     
       2. A timepiece according to claim 1, characterized in that the said turning rings are arranged inside the casing of the timepiece, and are provided with teeth, and in that a separate crown carrying a pinion in engagement with said teeth is provided for rotating each of the rings. .Iadd. 3. In a watch which includes indicating mechanism driven by a watch movement and wherein said indicating mechanism indicates hours and minutes, said movement and said indicating mechanism being supported in a watch casing; the improvement which comprises a stationary bezel; a turning bezel arranged inside said stationary bezel; said stationary bezel having a visible annular surface carrying indications of consecutive days of the week of at least five weeks; said turning bezel having a visible annular surface which is concentric with the annular surface of said stationary bezel, said turning bezel carrying numerals from 1 to 31 in consecutive order corresponding to the dates of a month having 31 days; each one of the date indications on the turning bezel being adapted to be placed in radial alignment with a day of the week indication on the stationary bezel; said stationary bezel and said turning bezel being supported independently of the watch movement; and means externally of said casing to effect manual turning of said turning bezel.
