UNIMATIC and Massena LAB are proud to present the third and final chapter of their NASA Space Exploration trilogy: The Modello Quattro U4S‑T‑SPW. Crafted in Italy from lightweight titanium with a special Cerakote ™ H140 bright‑white coating, the 40mm case houses a genuine meteorite dial. Each dial is cut from a fragment of an ancient iron‑nickel meteorite, a material forged in the vacuum of space over millions of years, traveling through the solar system before falling to Earth, where it was eventually recovered and meticulously prepared for horological use. Its distinctive surface reveals the Widmanstätten pattern, an interlacing crystalline structure that forms only during the slow cooling of molten metal at a rate of just a few degrees per million years. These intricate lines, created light‑years away from our planet, ensure that no two dials are ever alike. Each timepiece becomes a literal slice of cosmic history, carrying with it the story of its journey through time and space. Above the dial, the Super‑LumiNova® BG W9 markers and NASA "worm" logo are printed directly onto the 2.8mm flat sapphire crystal, creating a floating effect that adds depth and visual intrigue, giving the dial a distinct space‑inspired character. The release of the U4S‑T‑SPW follows two preceding collaborations with Massena LAB launched to celebrate NASAs Artemis missions, the U1-SPG NASA Artemis and UT4-SPT NASA Artemis II limited editions. NASAs upcoming missions, marking a renaissance of space exploration, will mark the first crewed return to the Moon since the Apollo program ended in the early 1970s. Looking ahead, these missions aim for a more ambitious (and historic) goal: sending the first astronauts to Mars. The U4S‑T‑SPW is built for professional performance with water resistance individually tested to 30 ATM (300m / 1000 ft). Its titanium case is paired with an 8mm screw‑down crown and a case back engraved with a detailed meteor comparison chart. Inside beats the Swiss‑made Sellita SW200‑1 b automatic movement, operating at 28,800 bph with a 38‑hour power reserve, 26 jewels, hacking seconds, and accuracy within ±12 seconds per day. Each watch is delivered on a white nylon keeper two‑piece quick‑release strap with a titanium Cerakote ™‑coated buckle, along with a cool‑gray TPU strap. Limited to just 60 pieces, the U4S‑T‑SPW will be offered exclusively at Geneva Watch Days 2025. Free U.S. shipping.
