Citizen Promaster Marine Eco-Drive Professional Diver 300 m: a professional diving watch with exceptional autonomy

The Citizen Promaster Marine E365 is a diving watch designed for professionals and underwater adventure enthusiasts. It stands out for its remarkable autonomy, its robust design and its features designed for the most demanding environments.

Record autonomy thanks to Eco-Drive technology

Equipped with the Eco-Drive Cal. E365 movement, this watch draws its energy from light, whether natural or artificial. Once fully charged, it offers an impressive 365 days of battery life, even in low light conditions, making it a reliable companion for long dives.

Design inspired by the deep sea

The design of the Promaster Marine E365 is inspired by the heritage of Citizen's professional diving watches, such as the iconic BN0156-05E, while incorporating modern elements. Its round 46 mm diameter case, its easy-to-use unidirectional rotating bezel and its thick, luminous hands guarantee optimal readability, even in the darkness of the deep. The DNA codes of the BN0156 are also present, such as the crown and the crown guard at 4 o'clock or the silhouette of the rotating bezel.

The dial has a subtle gradient, changing from a light shade on the surface to a darker shade at depth, evoking the mysteries of the deep. The caseback is decorated with a diving helmet, the universal symbol of underwater exploration.

Features for professional divers

The Promaster Marine E365 is a saturation diving watch, water resistant to 300 meters and equipped with a helium valve for deep-water diving. Its BENEBiOL™ strap, a polyurethane of vegetable origin, is both hydrolysis-resistant and environmentally friendly.
