The dial is crafted from aventurine glass with hand-applied mother-of-pearl inlays to create a 'Cosmic Rain' effect, mimicking shooting stars.
The minute repeater mechanism, including hammers and gongs, is displayed on the dial side, positioned between 9 and 11 o'clock.
The watch features a one-minute flying tourbillon equipped with a cylindrical hairspring, a design element borrowed from 18th-century marine chronometers.
The fully skeletonized HMC 909 caliber comprises 415 components and is hand-finished with Moser's signature double stripes.
Titanium was chosen for the case not only for comfort but also for its acoustic properties, enhancing the resonance of the minute repeater.
The skeletonization required a complete rethinking of the movement architecture to ensure acoustic quality and maximize visibility.
The cylindrical hairspring, produced by Precision Engineering AG, is shaped by hand and oriented perpendicularly around the upper stem of the balance staff.
The dial-side chiming mechanism, with mirror-polished hammers and gongs, is situated between 9 and 11 o'clock, allowing a view of the hammers in motion.
