Description

Universal watch. The subject of the present invention is a universal watch comprising a usual fixed hour dial, a rotary dial of twenty-four Neurs driven by the movement and a dial bearing indications corresponding to the time zones. This watch is characterized in that this latter dial is mounted rotatably, and in that means are provided which allow it to be rotated manually.

The attached drawing represents, by way of example, one form of execution of the object of the invention.

fig. 1 is a view of the watch, dial side, and FIG. 2 is a partial section along fI-II of FIG. 1, in which only the elements necessary for the understanding of the invention have been represented.

The watch represented comprises a fixed central dial of twelve Neures, designated by the above dttquel rotate hands 2, 3 and 4, respectively for hours, minutes and seconds. An annular dial 5, of twenty-four Nures, is rotatably mounted around the dial 1. This dial 5, driven by the movement through the intermediary of a timer nun represented, makes one revolution in twenty-four Nures. An annular dial 8, carrying indications corresponding to the time zones, is rotatably mounted around dial 5. It is operated manually by means of a crown 9 (fig. 2) adopts the rod designated by 10 Carries a conical pinion 11 meshing with a tooth crown of 12 on dial B.

The operation of this watch is as follows: To know the time in a given place, you must turn dial 8 once and for all by means of crown 9 until the name of the place where you are placed next to Number twelve of dial 1. The watch represented in fig. It is, for example, designed for use in the New York or Montreal time zone. The local time, eight Neures in the evening or twenty Neures in the example represented, is normally read on the central dial 1. The dials 5 and 8 make it possible to determine the corresponding time of all the time zones of the globe. . Thus, for eight o'clock in the evening in New York, it is one o'clock in the morning in Paris, ten Neures in Tokio and eighteen Neures in Mexico City. Dial 5 presents a Light Part and a Dark Part indicating, with dial 8, which Part of the world is in the day and which Part of the world is in RTI ID="0001.0270" WI="3" HE="4" LX="1584" LY="1876"> 1a. night.

This muntre also makes it possible to know the correspondence in any time zones of times different from the local time. To do this, it suffices to bring a time zone of dial 8 opposite a certain time on dial 5 in order to be able to read the corresponding hour on dial 5 opposite any time zone.

The dial 8 could be integral with a rotating bezel allowing it to be operated manually, the crown 9 being removed. The crown could also be replaced by a wheel situated in a plane parallel to that of the dial, above or below the latter, in particular in on-board watches or clocks.

This universal watch can be applied to wristwatches, pocket watches, clocks, clocks, or any other timepiece.

Claims (2)
