ArtyA Chorus & Skeleton Minute Repeater Tourbillon

The independent Swiss brand is making a name for itself with the queen complication of watchmaking: the minute repeater. Three new unique timepieces have just left the Geneva workshops, equipped with the tourbillon minute repeater movement developed as a tribute to MHC and its talented watchmaker Pierre Favre.

The ArtyA Chorus Minute Repeater is a direct descendant of the 3-gong minute repeater, regulator, and double-axis tourbillon – the most complex piece ever developed by the Genevabased manufacture. It inherits its predecessor’s characteristic case, yet is modernized and reduced in size.

The ArtyA Skeleton Minute Repeater is a reinterpretation of the round titanium model created for the celebrated ‘Lion’s Head’ and ‘Death is Calling’ two unique pieces developed specifically to bring out the resonating movement’s exceptional sound. This new iteration offers two one-off versions in a sandblasted case that houses a fully skeletonized caliber to highlight its beating heart.

The ArtyA Chorus Minute Repeater’s case evolved from the iconic ArtyA 3 Gongs Minute Repeater with Regulator. Clad in sapphire crystal on all sides, the case is truly a work of art. ArtyA’s sapphire savoir-faire and extensive experience in creating complete cases in this material made it possible to craft a superior curved crystal – to a degree that was not achievable on the original. Indeed, modernizing the case has given the piece a timelessness all its own.

Creating a minute repeater requires meticulous craftsmanship. Assembling the hammers, gongs, and levers demands unparalleled precision to ensure a harmonious chime with rich, distinct notes. The sandblasted titanium case is designed to enhance reverberation, with the domed sapphire crystal creating a magnificent resonance chamber.

In pursuit of perfect sound quality, the goal of these final pieces was to couple the auditory experience with a visual ballet. Here, the exceptional technical sophistication of the movement – already highly advanced – has been laid bare in skeletonized form. This allows for the rare and fabulous sight of its inner workings in action. Enabling the beholder to appreciate the craftsmanship through a skeletonized movement is an honor for the watchmaker who designed it, as their work is displayed in its purest form.

The ArtyA Minute Repeater movement

The complex mechanism of the minute repeater is designed to tell time through sound. Master watchmakers invented this device in an age when their clients didn’t have the convenience of a light switch: when the candles went out, the only way to tell time was through a chime. On the ArtyA minute repeater movement, the bridges were carefully designed and hand-angled with the help of an acoustics engineer to optimize the propagation of sound waves for power and purity.
