Neuhausen am Rheinfall, April 14th, 2026. H. Moser & Cie. reveals the Endeavour Minute Repeater Cylindrical Tourbillon Skeleton – a watch that refuses concealment. Here, the drama of sound and motion is set on the dial side, fully skeletonised, in a 40 mm titanium case shaped as much for resonance as for restraint.
The hammers and chimes step forward, mounted on the dial as a clear statement. Curved gongs share a single plane, their geometry and clearances rethought so that nothing collides and nothing distracts. With openworked bridges and airy structures, the movement reads like architecture – voids pulling the eye as much as metal. If you want secrets, look elsewhere.
An unexpected counterpoint sits at 2 o’clock: a small domed Funky Blue fumé sub-dial, the H. Moser & Cie. logo rendered in transparent lacquer like a quiet signature. Time floats, untroubled, while the rest vibrates, clicks and sings.
The case is an instrument. The sliding bolt runs on Teflon and integrates into the main plate to save space. The middle is hollowed to create a sound box, each internal volume tuned for transmission. Titanium – light, rigid, low damping – keeps vibrational energy alive. The result is a chime that carries longer and cleaner. Building a repeater is one thing. Tuning a melody is the real work.
Opposite the music, a one-minute flying tourbillon at 6 o’clock turns with a cylindrical hairspring inherited from 18th-century marine chronometers. Rising perpendicularly around the balance staff, its concentric form improves isochronism and lowers friction – a natural partner to the tourbillon. Precision Engineering AG, Moser’s sister company, shapes each cylindrical spring by hand, a process that takes roughly ten times longer than a flat spring. Patience you can see.
Inside, the hand-wound HMC 909 is fully skeletonised and deliberately restrained. Three-dimensional, 33.0 mm across and 9.6 mm high, it beats at 21,600 vph with 35 jewels and 415 components, delivers a 90-hour power reserve, and wears Moser double stripes. Finishing is hand-applied throughout, the tourbillon bridge skeletonised to lighten the view without stealing the scene.
Details remain considered: a 14.4 mm-thick titanium case with sapphire crystals front and back, a crown signed with an M, leaf-shaped hands, Roman numeral decals on the domed sub-dial, and a hand-stitched grey nubuck alligator strap with a titanium pin buckle engraved with the Moser logo. The edition is limited to 20 pieces. Functions are clear: hours, minutes, and a minute repeater that strikes hours, quarters, and minutes.
Two mechanical languages – resonance and regulation – share one stage. The watch breathes. The rest of us listen.
