H. Moser & Cie. have launched a new 20-piece limited edition version of one of their most complex haute horology creations: the Endeavour Minute Repeater Cylindrical Tourbillon Skeleton Cosmic Rain. It builds on the standard (if you can use such a word to describe a watch as complex as this) Minute Repeater Cylindrical Tourbillon model by introducing a new Métiers d’Art style dial. It’s this element that gives the watch its Cosmic Rain moniker. This watch is also H. Moser’s entry into the Mechanical Exception category of the GPHG 2026 – check our guide to some of the other independents competing at the GPHG here.
Let’s start with that new dial, which is positioned off-centre towards 2 o’clock. On the pre-existing standard model, that dial features a signature H. Moser blue fumé as seen on multiple watches like the Pioneer Cylindrical Tourbillon as well, albeit in the more classical execution of the Endeavour rather than the sporty Pioneer. For the Cosmic Rain edition, that has been swapped for a blue aventurine glass base that is inlaid with vertical strips of mother-of-pearl. The starry appearance of the aventurine provides the ‘cosmic’ while the mother-of-pearl supplies the ‘rain’.

I’ve not seen a multi-material dial execution like this from H. Moser before. H. Moser dials tend to focus on colour to the exclusion of all else, whether through regular dial colouring, enamel or stone. The Cosmic Rain is a step beyond that – pairing multiple materials, multiple textures and multiple patterns into a single display in order to create a specific visual image. It’s like walking through a Piet Mondrian gallery and suddenly finding a Van Gogh.

Around the new dial is a familiar haute horology watch: the 40mm diameter x 14.4mm thickness titanium-cased Endeavour Minute Repeater Cylindrical Tourbillon Skeleton. The minute repeater complication is visible at 10 o’clock with its hammers and gongs that chime the time while the tourbillon sits at 6 o’clock. The term cylindrical tourbillon means the hairspring coils on a vertical axis rather than spiralling outwards as normal, an innovation designed to further improve isochronism compared to a regular tourbillon. The movement that powers this all is the HMC 909 manual winding with 90-hour power reserve.

The H. Moser & Cie. Endeavour Minute Repeater Cylindrical Tourbillon Skeleton Cosmic Rain is limited to just 20 pieces at a price of CHF 378,350 (approx. £348,300). Ultimately, it’s just an aesthetic update to the previous version but I still really like the update they’ve done. As a card-carrying nerd, the Cosmic Rain theme in combination with the skeletonised architecture of the watch reminds me of the rain-soaked neo-futuristic landscape of the Blade Runner films.
