The Final Chapter in a Cosmic Story
UNIMATIC and Massena LAB are ending their NASA Space Exploration trilogy not with a whimper, but with a bang — or more accurately, a chunk of space rock. The new Modello Quattro ref. U4S-T-SPW, unveiled exclusively at Geneva Watch Days 2025, is the brand’s first watch to feature a meteorite dial. Only 60 will be made, making this both the finale and the rarest of the three collaborations.
Stacked from 25 images. Method=B (R=4,S=2)This release follows the earlier U1-SPG “NASA Artemis” and UT4-SPT “NASA Artemis II” editions — both tributes to NASA’s Artemis missions, which mark humanity’s first serious steps back to the Moon since Apollo and a staging ground for an eventual journey to Mars.
Where the first two models leaned heavily on white-and-black NASA visuals, this new piece pushes the narrative further: instead of referencing space, it contains space. By putting meteorite front and center, UNIMATIC and Massena LAB aren’t just paying homage to exploration — they’re literally putting the cosmos on your wrist.
A Slice of the Cosmos
The 40mm titanium case — finished in a bright-white Cerakote™ H140 coating — houses a genuine iron-nickel meteorite dial. Each slice reveals the Widmanstätten pattern, an interlaced crystalline structure that forms as molten metal cools at the glacial pace of just a few degrees per million years. The result is a surface that looks like abstract art but is, in fact, the fingerprint of a rock that survived a fiery entry through Earth’s atmosphere.
Adding to the cosmic effect, the NASA “worm” logo and lume indices aren’t printed on the dial, but on the 2.8mm sapphire crystal floating above it. This layering gives the dial unexpected depth, as if the markings are suspended in orbit. It’s a neat trick that feels more sci-fi movie prop than traditional horology.
Built for Space, Ready for the Ocean
Despite the NASA badge, the U4S-T-SPW isn’t heading to orbit anytime soon. But on Earth, it’s plenty capable. The titanium case is rated to 30 ATM (300m / 1000ft), more than enough for saturation diving, let alone space camp. A chunky 8mm screw-down crown keeps things sealed, while the caseback is engraved with a meteor comparison chart — a little Easter egg for those who actually flip their watches over.
Inside beats the workhorse Sellita SW200-1, an automatic Swiss movement running at 28,800 vph with 26 jewels and a 38-hour power reserve. It’s reliable, serviceable, and exactly what you’d expect for a tool watch that happens to be dipped in space dust.
Straps are suitably practical: a white nylon keeper strap with titanium Cerakote-coated hardware and a backup cool-gray TPU strap for when you’d rather not blind your wrist with all that white.
