Description

Technical Field

[0001] This invention belongs to the field of mechanical watches, and specifically relates to a timekeeping mechanism for a mechanical watch. Background Technology

[0002] In mechanical watches, especially chronographs with chronograph functions, a clutch and control mechanism are indispensable. In existing chronograph movements, the clutch is horizontally mounted, with a rotating gear engaging and disengaging with a stationary gear via a control mechanism to activate and deactivate the chronograph function. Alternatively, the chronograph control mechanism uses a cam, which reciprocates under the action of a control lever. These structures have the following drawbacks: the constantly rotating seconds wheel engaging with the stationary seconds gear can easily lead to tooth knocking, preventing the chronograph function from operating; the moment the gears engage, the amplitude of the oscillating mechanism drops instantaneously, affecting the stability of the movement; the seconds wheel and its module are relatively small, making manufacturing difficult; and the cam-based chronograph control mechanism is difficult to manufacture and has poor reliability.
