CITIZEN PROMASTER Professional Diver 300 m
The PROMASTER series from CITIZEN represents functionality and professional use for over 35 years. The latest model BN1024-01E in this series is the Eco-Drive Professional Diver 300 m. The watch is equipped with the light-powered in-house caliber E365 and has a power reserve of 365 days when fully charged.

In addition, many design elements of the most popular models from the PROMASTER Diver collection can be found in this new watch. It is designed as a saturation diver's watch and is therefore equipped with an additional helium valve and a water resistance of 30 bar (300 meters).

Update and upgrade of a popular PROMASTER model
This new model series is based on the popular PROMASTER diver's watch BN0156-05E and adopts many of its characteristic design elements. These include the crown and the crown guard at 4 o'clock, the shape of the indices, the hour and minute hands and the design of the rotating bezel.

The glossy dial is inspired by the dark coloring of the deep sea and changes to a deeper shade at the 6 o'clock position. The bracelet is made of BENEBiOLTM*2, a plant-based polyurethane. CITIZEN has chosen BENEBiOL for its bracelets because it is resistant to hydrolysis in the presence of moisture and has a lower environmental impact. The image of a diver's helmet, a universal symbol for divers, is engraved on the case back.
