# Skeleton Tourbillon Watches Endeavour Minute Repeater Cylindrical Tourbillon Skeleton By Amy Duong | Published 2026-07-22 | Fashion Source: Trend Hunter, https://www.trendhunter.com/trends/endeavour-minute-repeater References: [h-moser](http://h-moser.com/)  The [Endeavour](https://www.trendhunter.com/trends/endeavour-flyback-chronograph) Minute Repeater Cylindrical Tourbillon Skeleton Cosmic Rain is a limited-edition watch from [H. Moser & Cie.](https://www.trendhunter.com/trends/streamliner-tourbillon-concept-ceramic) that combines a dial-side minute repeater, a flying tourbillon with a cylindrical hairspring, and a fully skeletonized movement. Limited to 20 pieces, the 40mm titanium timepiece showcases exposed hammers and gongs on the dial alongside openworked bridges that reveal the hand-wound HMC 909 caliber. A domed aventurine subdial with hand-applied mother-of-pearl inlays creates the collection's signature "Cosmic Rain" effect, contrasting the movement's mechanical architecture with decorative craftsmanship. The HMC 909 movement is composed of 415 components and delivers a 90-hour power reserve. Its cylindrical hairspring, produced by [Precision Engineering AG](https://www.trendhunter.com/trends/ulysse-nardin-x-urwerk), draws inspiration from historic marine chronometers to improve isochronism while demonstrating traditional watchmaking techniques. Each aventurine fragment and mother-of-pearl strip is individually applied, making every watch unique. Image Credit: H.
