The minute hand 1d is attached to the tip of the cannon tube 2. The hour wheel 6 is supported by an hour wheel guide pin 5 fixed to the second base plate 4, and an hour hand 6 a is attached to a tip of the hour wheel 6. The torque of the second wheel & pinion 1 is transmitted from the second wheel 1a to the minute bevel gear 7b,
It is transmitted from the pinion 7a to the hour wheel 6.
