Safety device of minute repeater mechanism
Failure of the minute repeater most frequently occurs due to operation of the crown when the
repeater mechanism operates.
In most watches which are mounted with a repeater function, when the crown is pulled out to
adjust the hand position while the minute repeater is chiming, an abnormal load is applied to
the gears or lever to cause a failure.
In order to prevent a failure from occurring because of the time setting while the minute repeater
is chiming, this watch is provided with a safety device that prevents both operations from being
performed at the same time.
◎ The minute repeater cannot be activated while the time is
being adjusted.
