Citizen Eco-Drive Promaster Marine 1000M Professional Titanium Diver
BN7020-09E
The Citizen Eco‑Drive Promaster Marine BN7020‑09E is the pinnacle of professional dive engineering. Forged in Super Titanium, this flagship diver is built for the ocean’s most punishing depths yet remains astonishingly light on the wrist.
Driven by Eco‑Drive technology, it captures light and stores up to 1.5 years of autonomy, eliminating battery concerns even on extended expeditions. The bold power reserve indicator at 9 o’clock mirrors the dashboard of a performance machine — a constant reminder that this is a serious instrument for those who push limits.
Certified to ISO 6425 standards, the BN7020‑09E delivers 1000M water resistance, a helium escape valve, and a synthetic rubber strap with dive‑suit extender. Every detail is uncompromising, every feature designed for survival.
This is not fashion. This is a professional tool, trusted by divers worldwide when reliability is non‑negotiable.
