Introducing Unimatic × Massena LAB Introduce the Limited Edition Modello Quattro

Unimatic and Massena LAB have unveiled their latest collaboration, the Modello Quattro ref. U4S-T-SPW, launched exclusively for the Geneva Watch Days 2025.

This timepiece not only marks the conclusion of the NASA Space Exploration series but also represents a bold step forward for Unimatic, featuring the brand’s first-ever meteorite dial, a literal fragment of the cosmos. The watch embodies both brands’ shared pursuit of creativity and their homage to human ambition and exploration.

The Modello Quattro U4S-T-SPW features a 40mm titanium case with a height of 13mm (including crystal), enhanced by a Cerakote H140 bright white ceramic-polymer coating that recalls the aesthetic of a lunar spacesuit. 

Its 8mm screw-down crown ensures a robust water resistance of 300 metres, while a 2.8mm flat sapphire crystal with internal anti-reflective coating safeguards the dial. The titanium caseback is engraved with a detailed meteor comparison chart, underscoring the space-inspired theme.

Each dial is cut from an ancient iron-nickel meteorite, displaying the natural Widmanstätten pattern a crystalline structure formed over millions of years in space.

This is Unimatic’s first meteorite dial, and it delivers a striking floating effect as all dial elements are printed on the underside of the sapphire crystal with Super-LumiNova BGW9, including NASA’s historic worm logo at 6 o’clock. The openworked indices and matching aperture on the seconds hand counterweight, along with the skeletonized hour and minute hands coated in Super-LumiNova, create a luminous, airy aesthetic. The design palette is dominated by white and grey tones, punctuated only by the vivid red tip of the seconds hand.

Inside, the watch is powered by the reliable Sellita SW200-1 automatic movement, offering central hours, minutes, hacking seconds, a 28,800 vph (4 Hz) frequency, 26 jewels, and a 38-hour power reserve. Accuracy is rated at +/-12 seconds per day.

The watch is delivered with two straps: a white nylon keeper two-piece quick-release strap and a cool-grey TPU two-piece quick-release strap. Both are fitted with signed titanium buckles coated in the same Cerakote H140 bright white finish as the case.

Limited to just 60 individually numbered pieces, the Unimatic x Massena LAB Modello Quattro U4S-T-SPW is priced at €2,500 (approximately AED 10,800).
