This 300-meter dive watch’s bold styling and deep-sea credentials have earned it the nickname “Ecozilla.” The watch features a 48 mm silver-tone stainless-steel case with a unidirectional rotating bezel built for serious underwater performance.

Large hands and markers contrast sharply against the black dial and are treated with luminous coating for clear visibility in low-light and underwater conditions. A durable, easy-to-adjust black polyurethane strap provides a secure and comfortable fit.

Powered by any light source, Citizen’s Eco-Drive movement eliminates the need for battery replacements, offering reliable, long-term performance for divers and everyday wear.
