Acoustic Sonnerie with Flying Tourbillon
“Sound is the oldest form of precision.”
$95,000
Slate alligator leather
The Minute Repeater Tourbillon represents the absolute summit of Calibre's manufacture — a watch that speaks the time on demand through two hand-tuned steel gongs and simultaneously defeats gravity with a flying tourbillon cage. Activating the slide on the caseside sets the repeating mechanism in motion, announcing hours, quarter hours, and minutes in a sequence tuned to concert A pitch at 440 Hz.
Each Calibre timepiece is assembled, adjusted, and timed individually in our Geneva atelier. Expected lead time is 4–6 weeks from order confirmation. Complimentary delivery by insured courier.

Minute Repeater Tourbillon
Minute Repeater
Slide-activated repeating mechanism strikes hours on a low gong, quarter hours on a double strike of both gongs, and remaining minutes on a high gong — reading time acoustically to the nearest minute.
Flying Tourbillon
Single-axis flying tourbillon rotating once per minute, its cage suspended without upper bridge above the open-worked sapphire dial.
Surface Treatment
All bridges and plates receive côtes de Genève finishing, perlage, and hand-anglage to the interior angles — invisible to the wearer, essential to the maker.
