The UNIMATIC x Massena LAB Modello Quattro U4S-T-SPW pairs a Gibeon meteorite dial with a white-coated titanium case and NASA worm logo printed on the crystal. The 60-piece release was offered at Geneva Watch Days 2025; both brands’ current product listings show it as sold out.
What makes the U4S-T-SPW distinctive?
The defining visual feature is the contrast between the iron-nickel meteorite dial and the bright-white Cerakote finish on its 40 mm Grade 2 titanium case. Massena LAB identifies the dial material as Gibeon meteorite. Rather than printing the markings on the dial, UNIMATIC puts the NASA worm logo and Super-LumiNova BG W9 markers on the inside of the flat sapphire crystal, giving the display a layered look. The NASA graphic is a design element; the available product information does not establish NASA endorsement or sponsorship.
The crystal has an inner anti-reflective coating. UNIMATIC specifies a thickness of 2.8 mm; because Massena LAB’s product page gives conflicting thickness figures, that detail is best treated as UNIMATIC’s specification rather than a settled cross-brand figure.

What strap size fits the U4S-T-SPW?
The watch comes with a white nylon quick-release strap and a cool-gray TPU quick-release strap. UNIMATIC specifies 22 mm-wide straps for its watches, so “22 mm quick-release watch strap” is a useful search phrase for a replacement. Check that the replacement’s attachment is compatible with the watch; nominal width alone does not guarantee a fit. The package also includes a UNIMATIC pouch and warranty card, and UNIMATIC states a 24-month worldwide warranty.
