CAUTION
Each time the minute repeater mechanism is used, a power reserve of approximately
3 to 5 hours is consumed.
To prevent the minute repeater from being stopped in the middle of operation, it is
recommended that the mainsprings be sufficiently wound before the minute repeater is
activated.

Make sure that the crown is at the
normal position.
If the crown is at the first click
position, push it back to the normal
position.
3
Press the button.
The minute repeater audibly
chimes the currently indicated time
by the hour and minute hands.
* As the minute repeater is a
mechanically-actuated time
announcing device, an error of
approximately one minute may
occur between the time indicated
by the number of times the gongs
are struck and the time indicated
by the hands of the watch.

First mainspring
2
Second mainspring
The first mainspring is mounted on the front side and the second mainspring is mounted on
the rear side of the watch.
These mainsprings are the power source for the watch and minute repeater.
3
One-way clutch
The one-way clutch transmits and interrupts the power generated by the mainsprings to the
minute repeater.
The one-way clutch slips when the mainsprings are wound and is locked when the minute
repeater mechanism is activated. When winding the mainsprings, you can view the
movement of two small springs and the slipping one-way clutch.
4
Large hammer
The large hammer strikes the gong for a low-tone sound (sound source).
5
Small hammer
The small hammer strikes the gong for a high-tone sound (sound source).
6
Repeating rack
This is a mechanism for reading the number of times the gongs are struck.
Three repeating racks for the hour, 10-minute intervals after the last hour, and minute operate
in conjunction with each other.
When the button is pressed to activate the minute repeater, the repeating racks
instantaneously rotate and slowly return to the original position.
The number of times the gongs are struck is determined by the returning amount.
7
Slow governor
The slow governor controls the speed at which the mainsprings are unwound and regulates
the chime intervals.
When the button located at the 8 o’clock position is pressed, the slow governor rotates at a
high speed, and stops after chiming is finished.
It uses the viscosity of air to minimize the operating sound.
8
Sound output hole
This is a slit for releasing the sound, in which the gongs (sound source) are mounted.
