Citizen Promaster Dive Eco-Drive Watch, 3-Hand Date, ISO

Product Overview

The Citizen Promaster Dive Eco-Drive Watch is built for those who live by the water, explore the depths, or simply demand a timepiece that keeps up with an active lifestyle. As part of the renowned Promaster Sea collection, this watch blends professional diving functionality with sustainable innovation. It’s engineered to meet the rigorous demands of underwater exploration while offering everyday reliability on land. At its core is Citizen’s Eco-Drive technology—a system that converts any light source into energy, eliminating the need for battery replacements. Whether you’re descending to 200 meters beneath the surface or navigating city streets at night, this watch delivers consistent performance, readability, and durability.

Key Features

• Eco-Drive Technology – Powered by light, this movement ensures continuous operation without battery changes. Caliber E168 efficiently stores energy from natural or artificial light, keeping the watch running for months in darkness once fully charged.
• ISO 6425 Certified Dive Watch – Officially certified to international diving standards, this watch meets strict requirements for water resistance, shock resistance, magnetic resistance, and legibility underwater. This certification confirms its suitability for recreational scuba diving.
• Luminous Hands and Markers – The hands and hour markers are treated with high-luminosity material that charges quickly in light and remains visible for extended periods in darkness—critical for low-visibility dives or nighttime use.
• Unidirectional Rotating Bezel – Designed for safety, the bezel rotates only counterclockwise, preventing accidental overestimation of elapsed dive time. This feature allows divers to track bottom time accurately and avoid decompression risks.
• 200M Water Resistance – Rated for depths up to 200 meters (20 bar), this watch is suitable for recreational scuba diving, snorkeling, swimming, and water sports. It’s built to withstand pressure and environmental stress at significant depths.
• Stainless Steel Case with Mineral Crystal – The 44mm round case in silver-tone stainless steel offers a robust, corrosion-resistant structure. The mineral crystal provides scratch resistance and clarity, ensuring the dial remains readable over time.
• Black Polyurethane Strap with Buckle Clasp – The flexible, lightweight strap is resistant to saltwater, UV exposure, and wear. Its secure buckle clasp ensures a stable fit during dynamic activities, from diving to hiking.
• Green Dial with Date Display – The high-contrast green dial enhances readability, while the date window at 3 o’clock adds practical utility for daily wear. The clean layout ensures quick time checks, even in challenging conditions.
