The Citizen Promaster collection offers a range of function-forward professional sports watches that are designed for an active life outdoors, whether that is on land, at sea, or in the air. The Citizen Promaster Dive series consists of a diverse assortment of purpose-built diver’s watches that offer ISO-certified performance and all of the features that are required to spend a life exploring the mysteries of the ocean.
The Citizen Promaster Dive BN0200-56E features a 44mm case that is crafted from Citizen’s proprietary ‘Super Titanium’ alloy, which is five times harder and 40% lighter than traditional stainless steel. Just as you would expect from any true professional diver’s watch, the Citizen Promaster Dive BN0200-56E features a unidirectional rotating timing bezel, along with highly luminous hands and hour markers for maximum legibility, even while navigating dark murky waters. A screw-down crown, shatter-resistant mineral glass crystal, and solid titanium case-back help provide the Promaster Dive BN0200-56E with an ample and ISO-certified 200 meters of water resistance, while a matching Super Titanium bracelet fitted to the watch’s 22mm lugs creates a lightweight and ultra-durable package that is perfectly suited for everyday wear and use.
Powering the Citizen Promaster BN0200-56E is the Caliber E168, which is part of the brand’s Eco-Drive range of All Light-powered movements that are known for their reliable performance and maintenance-free ownership experience. Like all modern Citizen Eco-Drive movements, the cal. E168 found inside the Promaster Dive BN0200-56E is capable of powering itself with any ambient light source and can run for up to six months at a time in complete darkness after being fully charged for true grab-and-go timekeeping convenience.

With a history that dates back to the founding of the Shokosha Watch Research Institute in 1918, Citizen Watch Co. was formally established in 1930 with the goal of creating high-quality yet accessible timepieces for the Japanese market. Headquartered in Nishitokyo, Tokyo, Japan, Citizen is one of the world's largest and most vertically-integrated watch manufacturers. In addition to producing timepieces under its own name, Citizen also serves as the parent company for a number of other brands including Bulova, Alpina, Arnold & Son, Frederique Constant, Campanola, and Miyota. Citizen’s list of horological accomplishments is both long and impressive, including everything from creating Japan’s first fully-waterproof wristwatch to currently holding the title for the world’s most accurate movement, which is capable of astonishing precision within just one second per year.
