An example of the operation of the safety mechanism having the above configuration is as follows.
This will be described with reference to FIGS.

When the chronograph is in the start state, as shown in FIG. 19, the pressing portion 1251a of the transmission lever 1251 is separated from the reset button 1202, and the pin 1251c is moved by the elastic force of the transmission lever spring 1244 in the direction shown by the arrow a in FIG. It is positioned in a state where it is pressed against.
At this time, the pressing portion 12 of the second hammer transmission lever 1252b

In this state, as shown in FIG. 20, when the reset button 1202 is pushed in the direction of arrow a in the figure, the pressing portion 1251a of the transmission lever 1251 is reset.
2 and is pressed in the direction of arrow b in the figure to
c presses the transmission lever spring 1244 to elastically deform in the direction of arrow c in the figure. Therefore, the entire transmission lever 1251 rotates around the pin 1251d in the direction indicated by the arrow d. With this rotation, the first hammer transmission lever 1
Since the pin 1252c of the second hammer 252a moves along the through hole 1251b of the transmission lever 1251, the first hammer transmission lever 1252a moves around the pin 1252f with an arrow e shown in the figure.
Rotate in the direction.

At this time, the second hammer transmission lever 1252b

Even if the second hammer transmission lever 1252b is in contact with the pressing portion 1253c of the hammer intermediate lever 1253, the second hammer transmission lever 1252b
Because the stroke is absorbed by rotating around 52g,
The pressing portion 1253c is not pressed by the pressing portion 1252d. Therefore, the operating force of the reset button 1202 is interrupted by the hammer transmission lever 1252 and is not transmitted to the reset operation mechanism after the hammer intermediate lever 1253 described later. Therefore, when the chronograph is in the start state, the reset button 1202 is erroneously reset. Pressing the button 1202 can prevent the chronograph from being reset.

On the other hand, when the chronograph is in the stop state, as shown in FIG.
The pressing portion 1251a separates from the reset button 1202,
The pin 1251c is positioned in a state where the pin 1251c is pressed in the direction of arrow a in the figure by the elastic force of the transmission lever spring 1244.

202 and is pressed in the direction of the arrow b shown in FIG.
51c pushes the transmission lever spring 1244 and the arrow c shown in the figure.
Elastically deform in the direction. Therefore, the entire transmission lever 1251 rotates around the pin 1251d in the direction indicated by the arrow d. With this rotation, the first hammer transmission lever 1
Since the pin 1252c of the second hammer 252a is moved along the through hole 1251b, the first hammer transmission lever 1252a
It rotates around the pin 1252f in the direction indicated by arrow e.

At this time, the second hammer transmission lever 1252b
The pressing portion 1252e of the
b, the second hammer transmission lever 125
2b rotates in the illustrated arrow f direction about the axis 1252g. By this rotation, the pressing portion 1252d of the second hammer transmission lever 1252b comes into contact with and presses the pressing portion 1253c of the hammer intermediate lever 1253, so that the hammer intermediate lever 1253 is centered on the pin 1253d in the direction of arrow g in the figure. Will rotate. Accordingly, since the operating force of the reset button 1202 is transmitted to the reset operation mechanism after the hammer intermediate lever 1253 described later, when the chronograph is in the stop state, pressing the reset button 1202 resets the chronograph. can do. When this reset is applied,
