Citizen Parawater – Citizen Parashock

The term “Parawater” was the one used by Citizen to describe that the watch was water resistant.

In 1959 the company produced the first Japanese water-resistant wrist watch. This was the “Citizen Parawater”. It was powered by the Citizen Cal. 920(2B). Soon after, the Parawater completed two trans-Pacific tests and one in the Sea of Japan. The result, needless to say, was positive.  As time passed Citizen was growing as a company and exported more and more watches, so the term “Parawater” was changed to the universally recognized “Water resistant” somewhere around 1970-1973.

The term “Parashock” came to life in 1956 when the company produced the first shock-proof Japanese watch, known as the “Parashock”. So first was the “Parashock” and three years later the “Parawater”.

Even though you have a parashock and a parawater watch, please don’t treat it as a modern Casio G-shock. 🙂

Please respond.


  3. Hi Citizen Guy, my father had a few Citizen watches and he wore them all the time. Well, one at a time of course. He passed away last year and I am proud to own them now in his remembrance. Can you tell me more about the one I’ll describe below?

    The face is white in a square and ronded case. One the left of the face plate it says ‘Citizen’, on the right it says ‘para water’ and ’21 jewels’. On the far right is has a small window for the date.

    On the back it has a horseshoe shaped cadre with: ‘4-180470 TA WATERPROOF STAINLESS STEEL’
    Between the ends of the cadre, mid-centre, it says: ’63-1353 CITIZEN 10801222′

    I don’t know much about watches, but I think the model is a 63-1353. It is a hand-wound watch of some quality, due to the ’21 jewels.’ It’s working fine, by the way.

    Because it says PARA WATER (with a space, curiously enough), I think it must be from before 1972. The serial number seems to indicate that it is from August 1971, 1961 or 1951, or so. I’m guessing it’s from ’71 or maybe ’61. 1951 would probably be too early for this model?

    Can you confirm, and please, anything you can add is very welcome because I can’t find any proper info on this particular model. If it’s okay, I’ll ask about the other ones some other time.


  4. Hi Citizen Guy, sorry it took so long to read your post. I have been extremely busy with work and my studies.

    I have made some photos of the dial and case-back, but I can’t figure out how to attach these.

    I can’t open the case (yet), so I hope you can give you some idea of the true age of the watch without that image.
