Embodiment Construction

[0024] The invention relates to the field of automatic winding watches with an oscillating pendulum. The present invention proposes a solution to the problem of how to manufacture a power reserve display mechanism integrated in an oscillating pendulum, which is reliable, easy to implement and durable.

[0025] The oscillating weight 1 oscillates in a pivotal movement about a pivot axis D1, which is usually but not necessarily arranged at the center of the watch movement where the oscillating weight is placed. The watch includes a mainspring in a conventional manner, and the movement of the oscillating weight is transmitted to the mainspring, thereby winding the mainspring. The present invention is applicable to the oscillating pendulum 1 that can be set above or below the watch movement. For simplicity, the watch movement is not shown in the figure.

[0026] The present invention relates to an oscillating pendulum used for an automatic winding watch. The oscillating pendulum inclu...

Abstract

The invention concerns an oscillating weight (1) for an automatic winding watch, including a power reserve indicator device (100) integrated in said oscillating weight (1) and including means (20) for displaying the power reserve by comparison to complementary display means (30), said display means (20) and complementary display means (30) being integrated in said oscillating weight (1). Said display means (20) and complementary display means (30) are movably mounted to rotate synchronously, at a given moment, relative to said oscillating weight (1). The invention also concerns an automatic winding watch including an oscillating weight (1) of this type, whose movements are transmitted to a mainspring of said watch.

Description

Technical field [0001] The present invention relates to an oscillating pendulum for an automatic winding watch. The oscillating weight includes a power reserve indicating device arranged to be integrated in the oscillating pendulum for an automatic winding movement, the device including A display for displaying the power reserve by comparison with an auxiliary display, the display and the auxiliary display being integrated in the oscillating pendulum. [0002] The present invention also relates to a self-winding watch including an oscillating weight whose movement is transmitted to the mainspring of the watch, the oscillating weight including the above-mentioned type of power reserve indicating device. [0003] The invention relates to the field of automatic winding watches. Background technique [0004] In a self-winding watch, the movement of the wearer is transmitted to the mainspring via an oscillating pendulum and a reduction gear. [0005] The gear train of the automatic windin...
