The winding stem 7 is loosely fitted into a horizontal hole in the main plate 1, and a stepped portion 7b formed at the raised portion of the tooth split cutter of the tooth portion 7a at the tip engages with the mandarin duck 8. This allows the diameter of the winding stem 7 to be reduced, making it possible to create a thin wristwatch.
By shortening the length of the watch, it is possible to make a small wristwatch. 7c
is a beveled portion at the leading edge of the winding stem 7, which allows the mandarin duck 8 to be pushed up when installing the winding stem 7. Although a large external force is applied to the winding stem 7 from the rear seat (not shown), the tip including the tapered step 7b that engages with the mandarin duck 8 is not loosely fitted into the main plate 1, etc., so that the step 7b is not loosely fitted. There is no risk of breakage, and the winding stem 7 can be designed to have a smaller diameter as described above. The crown gear part of the small iron wheel 11 meshes with the wheel part 7a of the winding stem 7, and since the mandarin pin 8 and the cannula 9 are integrated, they continue to mesh even when the winding stem 7 is pulled out or pushed in, and is switched. Prevents crushing of the teeth, which tends to occur during operation. The small iron car 11 is rotatably placed on the switching lever 10 by a seat 11a and a stud 11b so as to provide an appropriate axial clearance, and the intermediate car 12 is also placed on the switching lever 10 by a stud 12a.
Similarly, it is attached to the switching lever 10. The switching lever 10 is held on the base plate 1 with a stud 10a. The portion 11b' of the stud 11b of the small iron car 11 that protrudes from the switching lever 10 is provided with a reverse slope to prevent it from slipping out from the lattice 9b of the cannula 9. Therefore,
The tilting of the switching lever 10 in the upper surface direction (back cover direction) can be corrected by the lever 9, and disengagement of the tooth part 7a of the winding stem 7 and the small iron wheel 11 is prevented. From the right end of FIG. 2, the magnet 6a inserted into the hole of the stator 17,
A rotor 6 having a pinion 6c fixed thereto via a seat 6b made of nylon resin, and a fourth wheel & pinion 5, a third wheel & pinion 4, and a center wheel & pinion 3 of the reduction gear train are shown. The shaft support of the rotor 6 in the direction of the lower surface (direction of the dial) is a polyacetal resin bush 18b implanted in the stator plate 18. 1h is a hole for confirming the operation of the rotor 6, and 2 is a train wheel bridge near the dial 35. The center shaft 1a is installed perpendicularly to the plane of the main plate 1 with high precision so that the tilting of the center wheel 3 and hour wheel 16, that is, the deflection of the hour hand 33 and minute hand 34, is minimized.
3a is a washer that softens the friction between the hour wheel 16 and the center wheel 3, and 32 is a dial washer. The Hinoura holder 15 moves in three directions approximately equally spaced from its center of rotation.
The three protrusions 14a provided at 4 restrict the downward direction. 39 is the back cover, and 36 is the windshield. When the winding stem 7 is pulled out and rotated, the rotation is transmitted to the rotor 6, and a needle setting operation is performed.

形態にしても良い。 FIG. 8 is a block diagram of the electronic circuit in the structure of this embodiment. The switch spring 8c, which is set to Vdd, switches a switch circuit 40 including a differentiation circuit and a shaping circuit. Oscillation/frequency divider circuit 4 in which the output of the switch circuit 40 is connected to reset R
1 has outputs Q 1 , 2 , . . . of appropriate flip-flop circuits at each stage. The waveform shaping circuit 42 is composed of a NAND circuit that inputs only the highest frequency one of the inputs through an inverter circuit.
A drive circuit 43 that sends an alternating pulse current to the coil 19
Output to. Further, the power supply terminals of these electronic circuits are connected via a switch 8c. Therefore, when the needle setting operation is completed and the crown is pushed back, the switch 8c closes and power is turned on to all circuit elements, but the frequency dividing circuit 41 is instantly reset, so that the coil 19 is The current flows for too little time to drive the rotor 6. When the lever is pushed back, a time period of about 10 mS, for example, about 10 mS, which is longer than the time for the needle rotation wheel train to disengage from the instruction wheel train and the deceleration wheel train, has elapsed. , the reset of the frequency divider circuit 41 is released and, although there is a delay of one pulse width, an output signal is immediately outputted from the waveform shaping circuit 42, and a pulse current flows through the coil 19. This is because, as mentioned above, the rotor 6 rotates when turning the needle, so the direction of the magnetic pole is not determined when turning the needle is finished, and when the flip-flop circuit in the drive circuit 43 is turned on. Since the stable state at the time is not determined, current is applied to the coil 19 immediately when the crown is pushed back, and if the output direction of the drive circuit 43 matches the magnetic pole direction of the rotor 6 mentioned above, one step is completed. This is because if the clock is not set, it is stopped, and then the rotor 6 rotates and moves the hands accurately using pulses at accurate hand movement intervals, so that even if the clock is set to advance, the clock will not be instructed to lag. Therefore, as in this embodiment, the battery 38 can be prevented from being consumed when the watch is stored by keeping the hands set, and there is no problem when the user sets the hands. Rotor 6 in
This eliminates the need for a slip mechanism and a brake mechanism between the winding stem 7 and the winding stem 7, resulting in a highly reliable watch. If the battery capacity is sufficient, the oscillation circuit and frequency dividing circuit may continue to operate.

ンのものに応用出来る。 In the above, since the rotor 6 and the reduction gear train are placed between the main plate 1 and the dial 35, and this part of the main plate 1 has an almost sealed structure when viewed from the direction of the back cover 39, These rotors 6
This protects the reduction gear train and allows for a durable watch with a long maintenance period. The electronic component block, which is less affected by dust, is placed on the back cover 39 side to simplify work such as rate adjustment, and the electronic component block and reduction gear train are arranged flat, making it a thin watch. At the same time, the base plate 1 suppresses the occurrence of holes due to milling in the reduction gear train parts and prevents dust from entering. It can also express functional beauty. Furthermore, since the reference thickness of the movement is the thickness of the main plate 1, the height position of the parts attached to the upper and lower surfaces is highly accurate. Since the pointer wheel loosely fits into the center shaft 1a, the deflection of the pointer is small and the overall thickness including the case can be made thinner.
If it is planted from the top of the main plate 1, it will be long enough to make full use of the thickness of the clock, and the vibration of the pointer wheel can be reduced. On the other hand, the deceleration gear train is checked when the dial 35 is not present, as in the past, but the gear train bridge 2 is shaped to facilitate this work. The moving part of the movement is the dial 3
Since it is in the direction of 5, it can be applied to designs using transparent dials.
