Unimatic's 600m ProDiver: the Modello Uno U1S outline in a taller case with a 3mm sapphire crystal, rated 600m, so it is its own model (the 2023 500m U1S-PD5 and the titanium U1S-T-PD6-B are separate models too). Sold as individually numbered limited editions, each recorded as a variant. Specification from Unimatic's spec sheets: 40mm case, 41.5mm across the bezel (recorded as the diameter), 49mm lug to lug, 12.3mm thick without the crystal and 14mm with it, 28.4mm case opening, 22mm drilled lugs, 316L brushed steel, 8mm screw-down crown, screw-down caseback with the conversion scale, individually tested to 600m, 120-click mono-directional bezel with a ceramic 60-minute insert with BGW9 markers, 3mm double-domed sapphire with anti-reflective coating on the inner side, white Super-LumiNova with orange emission on the markers, hour and seconds hands and BGW9 on the minute hand, date window at 6, 89g head and 107g on the TPU strap. Unimatic quotes the Sellita SW200-1 a at +/-12 s/day, 38h minimum and 41h typical power reserve and 26 jewels, without naming a grade or claiming regulation. Each edition is also sold as a bracelet set (refs. U1S-PD6-B-UBK and U1S-PD6-RB-UBK) with a brushed solid steel bracelet and the TPU strap as an extra, recorded as a second price on the same variant; the set sheets give the same watch specs. Three links per row are counted from photos; no clasp details are published. Unimatic gives 300 pieces per colour on both the strap and bracelet-set pages without saying how they are divided. The year is the store's 2026 tag on the bracelet-set pages. Prices are Unimatic's euro prices for Italy, VAT included; the strap versions were in stock and the bracelet sets sold out on the review date. Edition details. U1S-PD6-B (2026, 300): matte black dial and ceramic insert, white closed seconds rail and trims. U1S-PD6-RB (2026, 300): reflex blue dial and ceramic insert, matte white trims.
