There are three small dials in the watch that represent the calendar, the week, and the score dial. Looking from top to bottom, the top small dial shows the month, and it is the first crown that controls it, and the month can be adjusted by pulling it out. The second crown has three functions: if it is not pulled out, it is manually wound clockwise; if it is pulled out one gear, the day can be adjusted counterclockwise, and the calendar can be adjusted clockwise.

The leftmost subdial at nine o’clock shows the day of the week, which can be adjusted by pulling out the first crown. On the far right is the subdial at 3 o’clock, which shows the month, and the month can be adjusted by pulling out the third crown. The subdial in the middle, at six o'clock, shows 24 hours. There is a small window in the middle of the dial at the three o'clock and six o'clock positions, which displays the calendar. The second crown can be adjusted by pulling out the first gear, and the time can be adjusted by pulling out the second gear.
The dial at 12 o'clock is the score dial, the dial at nine o'clock is the chronograph dial, and the dial at six o'clock is the seconds dial. The window at the three o'clock position shows the calendar. The first crown is the push button, which has a chronograph function that can be started and paused. The third crown is also a button with a time function, which can be restored to its original position.
