In the present embodiment, the first transmission gear train is a single gear, which is an intermediate gear 42. The shaft of the intermediate gear 42 is fixedly arranged on the epicyclic gear 3, and the intermediate gear 42 is in driving connection with the shaft. When the epicyclic gear 3 rotates, the epicyclic gear 3 and the intermediate gear 42 rotate around the center of the epicyclic gear at the same angular velocity because the center gear 2 is fixed.

In the present embodiment, in order to facilitate the disassembly and assembly of the minute wheel 431a and the rotating shaft 44 for the maintenance of the watch in the later stage, the minute wheel 431a and the rotating shaft 44 are in frictional connection. The center of the minute wheel 431a extends vertically upward to form a shaft tube. The hour wheel 431b can be sleeved on the shaft tube of the minute wheel. The minute hand can be fixedly connected with the top end of the minute wheel, and the hour hand can be fixedly connected with the hour wheel 431b. The outer edge of the hour wheel 41 is provided with a cross wheel two-joint tooth 433. The cross wheel two-joint tooth 433 is a two-joint tooth combined by a cross wheel piece 4331 and a cross tooth shaft 4332. The cross wheel two-joint tooth 433 can rotate around its own axis, and the friction generated by the rotation is much smaller than the friction between the minute wheel 431a and the rotating shaft 44, thereby avoiding the relative rotation between the minute wheel 431a and the rotating shaft 44. The cross tooth shaft 4332 is in meshing connection with the hour wheel 431b, and the cross wheel piece 4331 is in meshing connection with the minute wheel 431a. When the hour wheel 41 rotates around the shaft sleeve 45, the cross wheel two-joint tooth 433 rotates around the minute wheel 431a and the hour wheel 431b. At this time, the position of the minute wheel 431a is fixed relative to the hour wheel 41, and the minute wheel 431a can rotate relative to the hour wheel 41. In other embodiments, the first transmission gear train can also be a plurality of gears or two-joint teeth in mutual transmission connection. The first transmission gear train drives the hour wheel 41 to rotate in a predetermined manner.

[0046] The timing unit 5 comprises a watch stem 51, a split gear 52 and an adjusting wheel 53 which can drive the pointer wheel to rotate. In the embodiment, the adjusting wheel drives the minute wheel to rotate. Specifically, the adjusting wheel 53 is fixed on the rotating shaft 44, the split gear 52 is in mesh with the adjusting wheel 53, the splines of the split gear 52 are in friction fit with the rotating shaft, and when the split gear 52 is subjected to external force, it can rotate relative to the rotating shaft. The split gear 52 is in driving connection with the gear on the watch stem 51. In the embodiment, a central timing wheel is coaxially arranged on the fixed center gear 2, which is coaxially arranged with the peripheral gear 3 and can rotate relative to the peripheral gear 3. In the embodiment, the central timing wheel is a double-toothed gear 54 which can rotate around its own axis. The split gear 52 can be in mesh with the double-toothed gear 54 or be in driving connection with the double-toothed gear 54 through a plurality of double-toothed gears with adjustable transmission ratio. Alternatively, the central timing wheel can be a single spline. The central timing wheel is in driving connection with the watch stem through the fourth transmission system 7. The fourth transmission system 7 comprises a plurality of double-toothed gears and / or gears which are in mesh with each other. Specifically, a vertical wheel and a crown wheel which rotate synchronously with the watch stem 51 are sleeved on the watch stem 51. The crown wheel and the vertical wheel are in mesh with the gears of the fourth transmission system 7, so that the watch stem can drive the central timing wheel to rotate. In the working process, as the energy of the mainspring in the mainspring box 11 is released, the peripheral gear 3 rotates, driving the time indication unit 4 to rotate around the center of the peripheral gear 3. Since the split gear 52 is in friction fit with its own tooth shaft, the split gear 52 rotates around its own axis with damping, so that the split gear 52 remains relatively stationary with its own tooth shaft when it is not subjected to external force. Since the adjusting wheel 53 is in mesh with the split gear 52 and is integrally designed with the rotating shaft 44, the rotating shaft 44 remains relatively stationary with the peripheral gear 3. The minute wheel 431a remains relatively stationary with the peripheral gear 3 under the action of the friction fit with the rotating shaft 44. Since the hour wheel 41 and the center gear 2 are in driving connection through the intermediate wheel 42, the hour wheel 41 rotates around its own axis. The double-toothed gear 433 rotates around the hour wheel 41 and is in mesh with the minute wheel 431a, so that the double-toothed gear 433 rotates around its own axis, thereby driving the hour wheel 431b to rotate around its own axis.The person skilled in the art should know that the transmission ratio between the minute wheel 431b and the minute wheel 431a can be controlled by setting the number of teeth of the gear, so that the transmission ratio between the minute wheel 431b and the minute wheel 431a is 1:12, so that when the minute wheel 41 rotates one revolution around its own axis, the minute wheel 431a rotates one revolution relative to the minute wheel 41, at this time the minute wheel 431b can rotate 30° around its own axis under the drive of the cross wheel two coupling teeth 433; during the time setting process, pulling the watch stem 51 makes the crown gear engage with the pinion gear, when the watch stem 51 is rotated, the torque is transmitted to the split gear 52 through the transmission connection, so that the split gear 52 rotates around its own axis, driving the adjusting wheel 53 to rotate, the adjusting wheel 53 rotates synchronously with the rotating shaft 44, and then the minute wheel 431a rotates around its own axis, completing the minute setting, at the same time, the hour is synchronously completed under the drive of the cross wheel two coupling teeth 433. The person skilled in the art should know that the watch stem 51 cooperates with the hand setting mechanism of the watch, which can drive the gears in the time setting unit 5 to rotate, or can separate the crown gear from the gears in the time setting unit 5, so that the watch stem 51 can rotate freely.

[0047] The function unit in another function area 31 on the epicyclic gear is the escapement speed regulation system, and the transmission unit is a second transmission unit 62. In this embodiment, the second transmission unit 62 includes multiple stages of two coupling teeth or gears. The escapement speed regulation system includes a balance wheel assembly 61, an escapement fork, and an escapement wheel. The escapement wheel is in transmission connection with the fixed center wheel through the second transmission unit 62. The escapement fork is arranged between the balance wheel assembly 61 and the escapement wheel. When the spring releases energy to make each gear in the movement rotate and work, the periodic swing of the balance wheel makes the energy release of the spring have a periodic law, thereby controlling the rotation speed of the epicyclic gear 3, and then making each gear such as the epicyclic gear 3, the minute wheel 41, the minute wheel 431a, and the minute wheel 431b reach a preset rotation speed through the transmission ratio between each gear, and displaying the time through the hands arranged on the minute wheel 431a and the minute wheel 431b. In other embodiments, the transmission system can also use a chain transmission or other transmission modes to transmit torque, such as a sesame chain transmission structure used in the movement. The person skilled in the art should know that the rotation speed of the balance wheel assembly 61 can be adjusted by setting fast and slow hands, eccentric weights, and the like, so as to adjust the fast and slow of the movement. This is a prior art and will not be described here. In other embodiments, the oscillator 6 can also be a quartz oscillator 6 or other devices that have periodic motion and can control the rotation speed of the mechanism. The quartz oscillator 6 controls the rotation speed of the output shaft of the motor through the circuit, and the escapement system controls the rotation speed of the edge gear of the barrel 11 through the periodic rotation speed of the balance wheel. At this time, the edge gear of the barrel 11 can be regarded as an output shaft.

[0048] The skilled in the art should know that the clamps can be integrated or separated, which are set by the positions of the wheel shafts of the gears on the epicyclic gear 3, and the wheel shafts of the gear and the balance wheel assembly 61 are fixed in the preset positions by the clamps and the epicyclic gear 3, so that the gears rotate stably.

[0049] The pin tube 46 is arranged on the edge of the hour wheel 41, and the cross wheel two-joint tooth 433 is arranged inside the pin tube 46. The revolution dial 47 can be a number dial or a star dial, and the revolution dial 47 includes the fixed sheet 471 and the revolution dial face 472. The fixed sheet 471 is fixed on the hour wheel 41 through the pin tube 46, and the middle part of the fixed sheet 471 extends vertically upward to form the insertion pipe. The revolution dial face 472 is inserted and fixed with the insertion pipe. The shaft pipe of the minute wheel 431a is inserted into the insertion pipe, and the revolution dial 47 is supported by the pin tube, and the revolution dial face 472 is separated from the shaft pipe of the minute wheel through the insertion pipe, so that the revolution dial 47 does not affect the rotation of the pointer wheel, and the shaft pipe of the minute wheel 431a can pass through the dial face of the revolution dial 47 and be connected with the minute hand. In other embodiments, the shaft pipe of the minute wheel can be replaced by the shaft pipe of the hour wheel or the second wheel according to the needs.

[0050] The cross wheel two-joint tooth 433 is arranged below the revolution dial 47, and the revolution dial (not shown in the figure) can be arranged above the epicyclic gear 3.
