A Modello Quattro UT4 on a Seiko VJ43B day-date quartz instead of the UT4's VH31, so a separate model. Its only edition, the UT4-TW (2026, 200), was made with South Park and celebrates the character Towelie: pale purple dial printed with Towelie, whose face changes daily in an 'expression' window at 12 (Unimatic: a day disc printed with Towelie's expressions); the photos show no date window, so the complications are recorded as hours, minutes, seconds and day. Specification from its spec sheet: 40mm case with a fixed monoblock bezel, 49mm lug to lug, 28.4mm case opening, 12.7mm without the crystal and 13mm with it, 22mm drilled lugs, brushed 316L steel (the page spec list says 316), 8mm screw-down 'Alchemical Sun' crown between angular crown guards (photos), screw-down UNIMATIC x South Park 'Towelie' caseback, individually tested to 300m, 2.8mm flat sapphire with anti-reflective coating on the inner side, Unimatic's 360° protection system (TPU movement holder, here pale purple), C1 lume, matte black open seconds rail, matte white trims, pale purple hands, 88g head and 94g on the strap; Unimatic quotes ±20 s/month and about three years, with no regulation claim. It comes with a Towelie purple quick-release TPU strap and a matching suede strap. The page header says it sold out on Unimatic's store and is now sold by Nordstrom; the Italian store data still lists it at 520 EUR including VAT, recorded. Nordstrom's page returns only a script shell to automated requests, so it has no store entry.
