Isotope's GMT, which shows the second time zone on a rotating central disc read through a Lacrima-shaped cut-out instead of a GMT hand, and the date as a coloured dot behind one of 31 holes in the dial. Spec table: brushed 316L steel (or black DLC), "Case diameter 41.5mm x 39.5mm (44.7mm with lugs)", height 14.2mm, domed AR sapphire, half exhibition screwed caseback (a Lacrima-shaped window; the solid part is engraved with world time offsets), single screw-down crown at 3, Super-LumiNova on the hands, 200m, Cordura strap 24mm tapering to 22mm. Movement: "Swiss made customised Swisstech or Landeron", automatic, 40h, 28 jewels, 28,800 A/h, -12/+12 s/day, with a three-year warranty; the caliber isn't named and either maker may have been used, so only the type is recorded. Versions: Olive Green, Black, White and Blue at £1,160; Olive Green DLC, Beluga Grey and Ruby (49 numbered pieces each) at £1,340; Full Black and Full White ("Snow White", 10 each) at £1,590. Every version was sold out on 2026-10-25 and the listing dates from January 2021; Isotope doesn't say it is discontinued, so the status is unknown. A Droplet steel bracelet (solid links and pins, brushed clasp, quick release) was sold separately for the steel versions at £248. Isotope's store prices include UK VAT. Two later collaborations, now sold out and listed without a price, share the spec table: the Cool Hunting edition (November 2021, with the New York publication Cool Hunting; bright yellow dial, extra quick-release leather strap, 100 numbered pieces, 10% of proceeds to Miles4Migrants; $1,250 at launch per Cool Hunting) and the Terra Maris edition (May 2022, with journalist Miguel Seabra; brown and blue dial with lumed indexes as well as hands, "Terra Maris" on the GMT disc, Lisbon instead of London marked on the caseback, steel bracelet plus brown leather strap, 49 numbered pieces; GBP 1,030 including taxes per Monochrome). Isotope's Terra Maris spec names a Landeron movement with Top finish. Weight isn't published.
