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 5 of its 14 options as this model (Nordblad, Orange, Yellow, Red and Green (no date) Sellita SW200); the others are in the other Goutte d'Eau files, split by movement and date. Swiss-made Sellita SW200 (Fifth Wrist names the SW200-1), 38h by Isotope's figure, -12/+12 s/day; the date isn't shown on these versions. Price: £519 for the Sellita versions per WatchGecko's April 2020 launch article; Fratello's 2021 review calls the Sellita version sub-€600. 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.
