With the Endeavour Minute Repeater Cylindrical Tourbillon Skeleton, H. Moser & Cie. unites three of watchmaking’s most demanding expressions: a fully skeletonised architecture, a minute repeater brought dial-side, and a flying tourbillon equipped with a cylindrical hairspring. Each element is complex on its own. Together, they create a unique watch where the interaction of sound, motion, and structure is on full display.

Powering this composition is the hand-wound manufacture calibre HMC 909, entirely skeletonised and built as a three-dimensional structure. Integrating over 400 components, it brings together the minute repeater and flying tourbillon within a single architecture, offering full visibility into its mechanical complexity. With its 90-hour power reserve and components finished and decorated by hand, this is traditional watchmaking pushed to its limits.
