Enquire at a salon- Twin hardened-steel cathedral gongs wrap the movement perimeter twice
- Centrifugal silent-strike governor removes mechanical background hum
- Sustained acoustic decay measured at 3.2 seconds per strike
Narrative
Two cathedral gongs, each wound twice around the movement’s perimeter, are struck by independently regulated hammers timed to a slide activator at 9 o’clock. The strike governor is silent — none of the gear-train whir a cheaper repeater lets through.
