An improved movement for a three hand quartz analog timepiece having a frame, a stepping motor with the motor pinion adapted to step once per second, and a plurality of coaxial output members rotatably mounted in the frame including a spindle for driving a 'seconds' hand and having a toothed seconds wheel driven by a two-pin rotor pinion, a two-pin reduction drive pinion connected to the spindle, a coaxial sleeve having a toothed minutes wheel and a coaxial sleeves having a toothed hours wheel. The improvement comprises a dual reduction gear assembly with a single shaft rotatably mounted in the frame having a toothed third wheel driven by the reduction drive pinion and having a first reduction pinion and a second reduction pinion directly driving the hours and minutes wheel, respectively, from the same shaft. The first reduction pinion is the two-pin type and the second reduction pinion is a spur gear.
