With starting prices north of $15,000, virtually every watch produced by family-owned Swiss luxury brand H. Moser & Cie. could be considered a grail watch.

But in my opinion, the Endeavour Minute Repeater Cylindrical Tourbillon takes the cake as Moser’s ultimate grail. It features arguably the brand’s most complicated movement, with both a cylindrical tourbillon and a minute repeater on full display in a glorious skeletonized hand-wound movement.

The original version of this watch, which is limited to just 20 pieces, seems impossible to top. But somehow, Moser has gone and made the watch even better with the striking new “Cosmic Rain” version.

Cosmic rain, man

The new Moser Endeavour Minute Repeater Cylindrical Tourbillon Cosmic Rain is almost indistinguishable from the original that launched at Watches and Wonders back in April.

It features the same sculptural Endeavour case measuring 40mm across and 14.4mm thick, made of hollowed titanium to act as a resonance chamber for the minute repeater.

It’s powered by the same Moser Calibre HMC 909 manual-wind movement that’s fully skeletonized to show off the dial-side gongs and hammers of the minute repeater at 10:00 along with the one-minute flying tourbillon at 6:00.

As before, the tourbillon features a unique, in-house cylindrical hairspring that oscillates in a mesmerizing 3D fashion while also providing greater stability and precision. The movement still boasts a robust 90-hour power reserve and has the exact same hand-finished decoration as before.

Hell, the watch is even mounted on the same strap made of hand-stitched gray nubuck alligator leather and secured with a titanium pin buckle.

So, what’s different? It all comes down to the eponymous “Cosmic Rain” subdial.

The original Moser Endeavour Minute Repeater Cylindrical Tourbillon featured a time-telling subdial at 2:00. Treated with the brand’s “Funky Blue Fumé” enamel and featuring a railroad minute track, printed Roman numeral indices and the brand’s wordmark in clear lacquer, it’s a beautiful dial, but is pretty par for the course for Moser.

The Cosmic Rain dial, meanwhile, is considerably more impressive.

Its domed subdial is composed of aventurine glass, which contains flecks of copper that cause it to resemble a starry night sky. There are actually two layers of aventurine in the dial, each a different color, creating Moser’s signature fumé gradient effect. The dial is then coated and fired in an oven multiple times to create an enamel finish.

Once that’s completed, tiny carvings are made into the dial, which are inlaid with ultrathin strips of mother-of-pearl that have been sculpted to match the curves of the domed dial. The final result is devoid of any markings or logo, fully showing off the beauty of the “Cosmic Rain” effect, which resembles a meteor shower against a starry sky.

Availability and pricing

The original Endeavour Minute Repeater Cylindrical Tourbillon isn’t exactly an affordable or attainable watch. Limited to 20 pieces and priced at over $415,000, it ranks among Moser’s rarest and most expensive creations.

The new Cosmic Rain matches the original in terms of rarity, with a production run of just 20 pieces, but thanks to its far more complex dial, it’s quite a bit more expensive at an eye-popping $440,000.

As far as I can tell, this makes it the most expensive watch in the brand’s current catalog on its website. So, yeah, I’d say it’s the ultimate Moser grail.
