Introducing: Isotope Hydrium Coconut Island Sunshine. Steel. And a coconut for a second hand. The Isotope Hydrium Coconut Island is what happens when summer meets serious watchmaking. Limited to just 20 pieces worldwide , this is the kind of wristwatch that doesn’t just tell time, it tells you to relax. Built on the solid foundation of the Hydrium platform, Coconut Island delivers the performance you'd expect: a 40mm case of micro-blasted 316L stainless steel, a screw-down crown, 1000ft / 300m water resistance, and a Swiss automatic movement, the La Joux-Perret . This movement, a first in our collection, offers a 68-hour power reserve and an accuracy better than +7/-7 seconds per day . But the magic happens above the surface. The sunburst silver dial catches the light like sunlight on a white-sand beach, warm, bright, and inviting. And it's the custom-designed hands that steal the show: the hour and minute hands are shaped like gently swaying palm trees , while the central seconds hand is a spinning coconut , orbiting your dial in perpetual island time. The tool-watch toughness of the case and bezel perfectly balances the playfulness of the display. This isn’t just a fun face; it’s a fully capable dive watch with the specs to back it up. Strapped to a soft, suede-textured tan leather band with our branded bead-blasted buckle, the watch feels casual, breezy, and coastal, even if you’re dreaming of the tropics from your desk. It’s summer distilled into a mechanical machine, the kind of piece that sparks conversation before you’ve even had your first piña colada . With only 20 examples available globally , the Hydrium Coconut Island is a rare, wearable reminder that not everything needs to be so serious. Sometimes, the best complications come with coconuts. Please note: Only 7 watches have been assembled and are available as part of the first batch . The remaining 13 watches from the second batch will be available at the end of August .
