The Citizen Eco Drive Promaster Diver BN0200-56E is a powerful ISO-compliant timekeeper designed for underwater exploration. This tough and durable watch is powered by Citizen's Eco-Drive technology, so it never needs a battery. The Super Titanium™ case and bracelet provide a lightweight and corrosion-resistant finish that is perfect for underwater activities, while the one-way rotating elapsed-time bezel, screw-back case, screw-down crown, and anti-reflective crystal offer excellent protection down to depths of 200 metres.
