The utility model discloses a minute hand planet shows drive mechanism during wrist -watch, wherein, the kinetic energy of core transmits for the hour wheel, divides dial and bottom plate as an organic whole through position nail union coupling, go up hour wheel fixed mounting the time take turns to, go up hour wheel and the meshing of planet wheel parts, planet wheel parts respectively with a planet centre wheel and a hour plate wheel meshing, hour plate wheel with the time idle wheel parts mesh, the wheel pipe of hour plate wheel passes the rotary hole on the branch dial to hour dish that the drive was installed on round pipe rotates, the time idle wheel part with the time idle wheel meshing, the time idle wheel and the meshing of hour wheel part, the time idle wheel drive hour needle of installing on the hour wheel part and rotate. The beneficial effects are that: because the power supply is by hour wheel output and adopt train meshing transmitting movement, consequently, has effectively avoided because the minute wheel load that the minute wheel direct output caused is too big, center gravity shifting causes the problem of minute wheel piece tendency drive inefficacy, in addition, ball bearing connects also the significantly reduced loss of core energy of bottom plate.
