The full hour
The mechanism is activated automatically at the full hour.
Mechanical hour repeater
Time you can hear.
A precisely tuned interaction of hammer and gong. One clear, defined sound at the full hour – mechanical complexity, deliberately reduced.
Schematic illustration
Mechanism ready
A classical complication. Refocused.
This is how time becomes audible.
Inside caliber HRP-01, a finely tuned mechanical repeater system turns the change of the hour into a brief, deliberately perceptible moment.
Hammer meets gong
The precisely calibrated hammer strikes the specially tuned gong.
One defined sound
A short, harmonious resonance audibly marks the beginning of the new hour.
Silence on demand
The pusher at 4 o'clock completely deactivates the strike without affecting timekeeping accuracy.
Presence without intrusion
Why only once an hour?
Unlike frequently chiming sonnerie or quarter-striking mechanisms, HREPET is deliberately restrained. The sound becomes a special moment – not a permanent companion.
A clear moment
One brief sound marks the change of the hour – precise, intelligible and deliberately reduced.
Everyday ready
No recurring signals every quarter-hour. The repeater remains discreet in the office, a restaurant or everyday life.
Switchable
In quiet surroundings or at night, the hour strike can be completely silenced with the pusher at 4 o'clock.
Not constant. Not intrusive. Exactly once an hour.
