H. Moser & Cie. introduces mechanical watchmaking at its most complex with the Endeavour Minute Repeater Cylindrical Tourbillon Skeleton Cosmic Rain. This limited edition of 20 pieces merges auditory, visual and kinetic innovation into a single 40mm titanium case.
The watch performs on three sensory levels. The minute repeater mechanism produces acoustic chimes when activated, translating time into sound through dial-side hammers. The cylindrical tourbillon and hairspring create constant motion visible through the skeleton dial, where traditional components give way to open frameworks. A cosmic aventurine and mother-of-pearl subdial adds visual depth with shifting color palettes that respond to light.
Technical specifications underscore H. Moser & Cie.'s commitment to haute horlogerie. The cylindrical hairspring represents a departure from traditional flat designs, improving isochronism and precision. The 90-hour power reserve extends wear time between manual winds, a luxury in complicated watches. Every element serves both mechanical function and aesthetic purpose.
The Endeavour collection has become H. Moser & Cie.'s flagship for experimental horology. Previous iterations pushed boundaries with perpetual calendars and unusual materials. This Cosmic Rain edition pushes further into multisensory territory, treating the watch as an experience rather than mere timekeeping instrument.
At this rarity level—20 pieces worldwide—the watch targets serious collectors investing in mechanical art. H. Moser & Cie. remains among Switzerland's independent watchmakers, controlling production entirely in-house. This vertical integration allows the precision required for minute repeaters and cylindrical tourbillons without compromise.
The Cosmic Rain distills contemporary watchmaking philosophy: combine traditional complications with modern materials and sensory engagement. Titanium weighs less than precious metals while offering dur
