CITIZEN Diver´s 1000 Meters Professional Diving Promaster Watch with Black Rubber Strap
The world's first light diving watch suitable for saturation diving. The new flagship of the Promaster Marine collection uses a wide range of Citizen technologies, resulting in robustness and even greater water resistance.
A diver's watch, which must be suitable for 1000 m saturation dives, must not only undergo the water resistance test, but also a test in which the diver's watch remains 15 days in a pressure chamber which contains helium and oxygen or 100% helium gas. It is then returned from the pressure chamber to the atmosphere outside the pressure chamber in 3 minutes and exposed to 125 bar during this high-speed decompression. This requires the best advanced materials and technologies.

The clock that never stops, wherever you are.
One of Citizen's challenges: to develop a technology that guarantees the continuity of the clock's operation, anywhere in the world. In 1976, we invented the first light-fed analog quartz watch that works exclusively using light as a source of energy. This technology, now known as Eco-Drive, can generate energy from any light source (artificial light, natural light and even in dim light) to continue the operation of the clocks without replacing the battery.
Beyond the limits of matter.
This is the decisive step that Citizen has taken to improve the extraordinary characteristics of a mineral such as titanium. The Super Titanium of Citizen maintains the great lightness typical in titanium but, thanks to an exclusive process its resistance is five times higher.
