Abstract:
Provided is a countdown device for a watch with a convenient and quick operation, a simple structure and a wide application range. The countdown device comprises an outer ring of a watch dial, a watch dial, a first pointer module, a second pointer module (1) and a gear drive mechanism, wherein the first pointer module and the second pointer module (1) are provided in the watch dial, and when the outer ring of the watch dial rotates, the outer ring of the watch dial rotates around the watch dial to drive the gear drive mechanism to store energy, and when the outer ring of the watch dial stops rotating, the gear drive mechanism drives the second pointer module (1) to change and display the countdown. A countdown mechanism is controlled by means of a watch dial and a gear mechanism, which is convenient to use; a countdown function is integrated in a traditional mechanical watch, simultaneously realizing the functions of good aesthetics and practicality; and a watch dial is used as an impetus source of a countdown by using the design of a clockwork spring to control the movement of pointers.
