Introducing: Isotope Hydrium RG — British Racing Green Orange
Start your engines. Isotope is back on track with the Hydrium RG, a limited edition watch inspired by the pulse-pounding legacy of British motorsport. Drenched in deep British Racing Green and supercharged with high-contrast orange accents, this timepiece is a bold tribute to the adrenaline-fueled world of endurance racing. Limited to just 100 pieces worldwide, it’s one of those Hydriums destined to disappear fast over the horizon and become a rare classic.
The dial sets the tone immediately: a rich green canvas accented by a high-octane checkered racing chapter ring filled with Super-LumiNova, evoking pit lanes and finish lines from motorsport’s golden era. The orange second hand, styled like a vintage racing gauge needle, offers a subtle yet unmistakable nod to the instrument clusters found in classic British Le Mans and Formula 1 cars. Even at a standstill, the Hydrium RG feels like it’s in motion.
At its core is the trusted 40mm Hydrium case, carved from micro-blasted 316L stainless steel for a stealthy matte finish. Like all Hydrium models, it is built to dive, featuring 300m or 1000ft of water resistance, a unidirectional bezel, and a screw-down crown that makes it as technically sound as it is stylistically striking.
It comes paired with a bold high-contrast orange FKM rubber strap, ensuring both all-day comfort and standout presence. The strap’s textured surface and punchy colour reinforce the racing theme, whether you're gripping a steering wheel or a morning coffee at pit lane.
Inside, the Swiss automatic La Joux-Perret movement delivers 68 hours of power reserve, with a custom rotor visible through the display case back. It’s the only glimpse under the hood you'll ever need.
With just 100 pieces available globally, the Hydrium RG British Racing Green Orange celebrates mechanical precision, vintage motorsport, and British grit. It’s a driver’s watch for the road, the sea, or wherever your next lap takes you.
Please note: Only 15 watches have been assembled and are available as part of the first batch. The remaining watches from the second batch will be available at the end of August.
