The Modello Quattro U4S in solid 18K gold, so far one edition, recorded as a variant: the gold piece of the 'Ore' capsule that the Swedish architects Claesson Koivisto Rune designed for the opening of Unimatic's Milan flagship store, released there during the April 2023 Salone del Mobile (designboom), with the steel U4S-MEOS (Modello Quattro U4S) and the bronze U4S-MEOB (Modello Quattro U4S Bronze). Its page links no spec sheet. Specification from its description and page header: 40mm solid 18K gold case (yellow in the photos), fixed monoblock bezel and crown guards (photos), 8mm crown, 2mm screwed-in caseback, individually tested to 300m, flat sapphire with anti-reflective coating (side not stated), Swiss Sellita SW200-1 b at 28,800 bph with 38h of power reserve and hacking seconds, without a grade or regulation claim. Lug to lug, lug width, thickness, case finish and weight are not given for this edition (the steel and bronze U4S cases measure 49mm lug to lug with 22mm lugs), and the crown is not called screw-down. The dial has no hour markers and no lume is mentioned, and the photos show no date window, so complications are hours, minutes and seconds. The price is the euro price for Italy, VAT included, still shown on the sold-out product page. Edition details. U4S-MEOG (2023, 10): circular brushed 18K gold dial with an acid-etched logo and king red trims, brushed 18K gold skeleton ladder hands, king red seconds hand, UNIMATIC x Claesson Koivisto Rune caseback, king red TPU strap with a brushed solid 18K gold buckle.
