Marnaut is an independent watch brand founded in 2018 by Mario Jutronić, based in Croatia. The brand draws its core design identity from Jutronić’s childhood spent snorkeling along the Adriatic coast around the island of Brač. Collectors favor Marnaut for its signature sea urchin-inspired dial layout featuring symmetrical radial luminous markers, combined with Swiss mechanical movements and German manufacturing. Key models from the brand include the Dark Surge, Seascape, and Safe Harbour dive watches.
