CITIZEN Revives the Spirit of the Iconic Parawater with the new Kuroshio ’64 as part of the Citizen Asia Limited Series
The Parawater, the result of Citizen’s research efforts, was the first completely water and dust resistant watch by a Japanese watchmaker, and it was so named due to the technical innovation of water resistance that was the highlight of the watch, with the combination of the word “para” meaning protection and “water” to indicate that the watch was protected from water. To underscore the importance of this innovation, the name of the watch, Parawater, was placed on the dial where the logo of the brand would normally be.
The Parawater was rated to a depth of about 5 bar (50 metres), and it achieved its level of water protection due to the use of O rings that were made of a special rubber (butadiene acrylic nitrile copolymer). One large O ring was mounted on the case back, and this in conjunction with an extensively modified crown and tube assembly each with smaller O rings, made sure that the movement of the watch was completely sealed from water and dust.

One interesting detail that ties the Parawater to the new Kuroshio ’64 is that the retail price of the watch at the time of release was JPY 6,000, which was affordable given that the starting salary of a highschool graduate at the time was about JPY12,500.
The first extreme test, though not officially organised by the company, took place in 1962, when two Citizen Parawater watches accompanied Japan's most famous yachtsman, Kenichi Horie, on his successful solo crossing of the Pacific Ocean on the “Mermaid” Yacht. Just 23 years old at the time, Horie was the first man in history to make a non-stop solo crossing of the Pacific Ocean.
While this “test” might have showcased the real-world performance of the Parawater by a sportsman using it in extreme situations, more were to come that would further demonstrate what the watch was truly capable of.
In 1963, the Japan Maritime Self-Defense Force and the Tokyo University of Marine Science and Technology were about to embark on an ocean current survey, with bottles dropped in the sea with a survey form contained within, for people who picked them up to send back. This survey was modified in conjunction with Citizen, as it was the perfect opportunity to do the ocean current survey and a performance test of the Parawater at the same time.

Over the course of the year, 140 buoys were launched on four separate occasions, with the furthest report of buoys found coming from Oregon in the USA and Vancouver in Canada.
In 1964, the test was extended and named “Kuroshio 64” after the Kuroshio current that flows past Taiwan and the southeast coast of Japan. For this test, 47 buoys with a Parawater watch were each dropped off the coast of the Sanin sea.
It’s interesting to note that in all the instances of found buoys, all the watches that they contained were checked and found to be functioning perfectly, which is a remarkable testament to the technical achievement of Citizen in creating the Parawater.
Seen here is the advertisement of the project in 1963. Citizen Parawater watches in their distinctive buoys are thrown overboard for the first major test in 1963.

Powering the watches is Citizen’s own Calibre 8310, an automatic movement that features a useful power reserve of 60 hours and hacking seconds functionality.
Of note is the dial design, embossed with a pattern that is inspired by ocean waves, and that also adds visual interest due to the texture. As well, the dials that the watches will be launched in - dark blue, black, dark green, beige and silver white - are the various colours that the ocean can appear in.
The packaging of the Kuroshio ’64 takes inspiration from the buoy design of the namesake test in 1964.
