Claim:
1. A horologe equipped with a timekeeping system, said timekeeping system comprising: a winding mechanism providing power for a second hand, a minute hand and an hour hand; a mechanical transmission wheel train engaged with said winding mechanism and driving said second hand, said minute hand and said hour hand to operate, said mechanical transmission wheel train comprising a tourbillion mechanism, said tourbillion mechanism driving a second wheel that is connected with said second hand to make said second hand rotate, wherein said mechanical transmission wheel train further comprising a second transmission wheel, said second transmission wheel being located at the output end of the mechanical transmission wheel train and meshing with said second wheel, the rotational speed of said second wheel driven by said mechanical transmission wheel train being faster than that of the second wheel in standard time; an accuracy control device comprising a timekeeping motor for driving a rotor to make it rotate, the timekeeping accuracy of said timekeeping motor being controlled by a quartz crystal oscillator; and an electronic transmission wheel train connected with said rotor and comprising a first transmission wheel, both said first transmission wheel and said second transmission wheel being provided with three wheel pieces, a first wheel piece of said first transmission wheel being a gear wheel meshed with said rotor, a first wheel piece of said second transmission wheel being a round wheel piece with a groove, a second wheel piece of said first transmission wheel being provided with a plurality of first wheel blades, an outer edge of said first wheel blade being in an inward-concave arc shape meshed with said round wheel piece, a third wheel piece of said first transmission wheel being provided with a plurality of second wheel blades, a second wheel piece of said second transmission wheel being a long-arm shaped wheel piece which can extend in between two adjacent second wheel blades, and a third wheel piece of said second transmission wheel being a gear wheel meshed with said second wheel.
