Since Japan’s Heian period, Ama divers have practiced the art of free diving—reaching depths of up to 30 meters in search of pearls and the ocean’s abundant harvest. In honor of their legacy, Helianthus presents the Isobue GMT Diver, a timepiece that celebrates tradition, endurance, and the quiet power of a life spent in the sea.
Named after the distinctive whistling breath—isobue—used by Ama divers as they surface, this all-white watch pays homage to their traditional diving attire. With subtle design cues drawn from their world beneath the waves, the Isobue is both a tribute and a tool for those who move between worlds.
