The upper right button is pressed to start/stop the chronograph function. The lower right button is pressed to reset after the chronograph function has been stopped. Both upper right and lower right buttons are installed with a screw-on mechanism to prevent the button from being pressed if screwed on. In the middle is the screw-on type crown, which is pulled out with one click to adjust the time. The movement has a hacking function to stop secondhand while adjusting the time.
As we all know, the Dandong 4130 chronograph automatic movement is used in high-end homage watches. This watch uses the Dandong 4801, an upgraded edition of 4130. These two movements are essentially the same except for the self-winding mechanism, of which the 4130 is double-directional winding, but the 4801 is single-directional winding. From now on, Dandong Watch Factory will only make the 4801. The old 4130 is phased out.
This 4801 automatic runs stably at a high vibration of 28800 per hour. The subdial at 3 o’clock counts minutes, with a maximum of 30 minutes. The subdial at 6 o’clock counts seconds per minute. The subdial at 9 o’clock counts hours, with a maximum of 12 hours. A central long secondhand sweeps across the dial to count seconds.
