The third NASA-inspired collaboration between UNIMATIC and Massena LAB has a meteorite dial wrapped in specially coated titanium.
UNIMATIC and Massena LAB are old friends at this point, and we’ve covered no fewer than five watch collaborations since 2020. The latest Modello Quattro U4S?T?SPW sales are limited to Geneva Watch Days 2025, but those lucky enough to attend and get their hands on one are in for a treat. The watch celebrates NASA’s Artemis missions with next-generation rockets to launch crews back to the Moon and eventually Mars, and it’s the last of a trilogy series with prior U1-SPG “NASA Artemis” and UT4-SPT “NASA Artemis II” limited editions. This latest model has a meteorite dial and a titanium case, really hammering home the space-age theme.
The titanium case has a special Cerakote H140 bright white coating, which has a moon spacesuit vibe from the 1970s. It measures 40mm in diameter and 13mm in height with crystal (49mm lug-to-lug). The guarded 8mm crown screws down to ensure a robust 300-metre water-resistance rating, while a 2.8mm flat sapphire crystal with an internal AR coating protects the dial. The 22mm lugs are drilled, and the watch comes with two straps: a white nylon keeper two-piece quick-release strap and a cool-grey TPU two-piece quick-release strap. Both have signed titanium buckles with the same Cerakote H140 bright white coating as the case. The solid case back is engraved with a detailed meteor comparison chart, referencing the dial.
This is UNIMATIC’s first meteorite dial and features a crystalline structure formed over millions of years in space, known as the Widmanstätten pattern. The meteorite surface is unmarked as all dial elements are printed on the underside of the crystal with Super-LumiNova BGW9, including NASA’s worm logo above 6 o’clock. The indices are openworked, and the seconds hand counterweight has a matching aperture, while the hour and minute hands are also openworked and coated with Super-LumiNova. It all culminates in a bright and floating aesthetic. Everything is white or shades of grey from the meteorite, save for the red tip on the seconds hand.
Powering the Modello Quattro U4S?T?SPW is a Sellita SW200-1 b automatic (the b stands for no-date) with 26 jewels, a beat rate of 28,800vph (4Hz) and a power reserve of 38 hours. Functions include central hours, minutes and hacking seconds. Average accuracy is rated at +/-12 seconds per day, and it’s a direct alternative to ETA’s 2824-2.
The Modello Quattro U4S?T?SPW is limited to 60 pieces and individually numbered, and is only available at Geneva Watch Days 2025 from September 4th to the 7th. The retail price is EUR 2,500 (excl. VAT). For more information, please visit massenalab.com and unimaticwatches.com.
