Promaster Diver 300 m BN1025-08L

The BN1025-08L is part of the Sea of Silence models from CITIZEN’s Unite with Blue limited-edition collection, created in... celebration of the world’s oceans. This professional-grade diver’s watch is powered by CITIZEN’s Eco-Drive technology, offering a full-year power reserve using light alone. The dial features structural colour technology in deep blue, inspired by the calm, glittering sea. Created without pigment, the ink relies on light reflecting off microstructures to express ever-changing tones that evoke the shifting moods of the ocean. Designed for saturation diving, the watch is equipped with ISO-compliant 300-meter water resistance, a helium escape valve, and an anti-reflective sapphire crystal. The BENEBiOL™ strap, made from plant-derived polyurethane, reinforces the model’s commitment to sustainability. Bold and environmentally conscious, this timepiece captures the spirit of the sea with every detail.
