Description

Fan-shaped three-prong mechanical movement and mechanical watch

technical field

The utility model relates to the technical field of clocks and watches, in particular to a fan-shaped trident timekeeping mechanical movement and a mechanical wrist watch.

Background technique

Mechanical watches can usually be divided into the following two types: hand-wound and automatic-winding watches (AUTOMATIC). The power source of the mechanical watch is powered by the mainspring in the movement, which drives the gear and then pushes the hands of the watch.

Manual mechanical watch, hand-wound movement, by turning the crown of the watch, the mainspring in the watch movement is fully wound, and after the mainspring is fully exhausted, the gears are driven to run, and the hands are pushed to travel time.
