Isotope's first dive watch, a compressor-style case with an inner rotating bezel worked by a crown at 2 (four gaskets) and a screw-down time-setting crown at 4, designed with ice freediver Johanna Nordblad. Shared spec table: brushed 316L steel, "40mm X 44mm (with lugs)", height 12.7mm with the SW200 or 13.4mm with the Seiko, AR sapphire, screw-down caseback (exhibition on Orange, Yellow, Green and Red; solid and etched on the Nordblad special edition), Super-LumiNova BGW9 on hands, inner bezel and sandwich dial, 200m, 22mm brushed steel bracelet with an extension clasp for wearing over a wetsuit (the separately sold Goutte d'Eau bracelet has solid links and pins and a diver extension). The store listing sold 2 of its 14 options as this model (Nordblad (date) NH35 and Orange (date) NH35); the others are in the other Goutte d'Eau files, split by movement and date. The date versions are labelled NH35 in the store options; Isotope's spec only names the NH38 for its Japanese movement, which has no date, so the NH35 named in the option labels is recorded. The 13.4mm height and the -20/+40 s/day accuracy (Seiko's own figure, not a regulation claim) are Isotope's for the Japanese versions. Price: £379 for the Seiko versions per WatchGecko's April 2020 launch article. Each watch has an etched serial number. Every option was sold out and listed without a price on 2026-10-25; Isotope doesn't say the model is discontinued. Weight and crystal shape aren't published.
