Abstract:
A quartz watch movement includes a minute wheel connected to a handsetting wheel by an intermediate wheel, a shaft of a third wheel placed in a shaft hole in a main plate, elastic connection structures being rotated by a third-wheel shaft gear and a minute wheel piece gear which are engaged together and are arranged between a minute wheel tube and the minute wheel piece gear when a stem is pulled or the minute hand is adjusted through the handsetting wheel, the intermediate wheel and a minute wheel shaft gear, and a second-hand stop lever detachably connected to a second-hand stop electrode. The elastic connection structures are arranged between the minute wheel tube and the minute wheel piece gear, so that the quartz watch is accurate in travel time and has the function of efficiently adjusting the hour hand and the minute hand when omitting a handsetting middle wheel.
