Citizen Jet (Super Jet) Auto Dater


Citizen is famous for a lot of innovations and really cool watches and we can not talk about Vintage Citizen Watches without mentioning the Jet movements. What is a Jet calibre? Well… it is an in house Citizen made one, an automatic with a ring rotor unlike the common oscillating central mounted one that everybody is familiar with. Most of the people think that it is the first automatic calibre developed by our loved manufacture but it is not quite like this. In fact the first one was the Auto. But that one was soon dropped and in 1961 The Jet came to life, and what a fabulous one it was; short lived (1961 – 1967) but so beautiful. It came in a simple three hands watches, with or without a date and even a final day – date version.

Today I will introduce to you the (simple, dress style, non diver) date version, the easiest to find and enjoy the wonderful movement.

As you can see it came with a variety of dial colors and configurations. The crystal is acrylic and usually they are on a leather strap. Most of them are made of stainless steel, a lot are gold plated and a only few are solid gold. All of them have a Jet movement and display the time (with a central non hacking second hand) and the date. The date is non quick set but changes by moving the hour hand over midnight and back to 21 and again at midnight. Some movements had a special feature called Easy Change that allows a fast set mechanism to advance the date. Just pull the crown in and release it and the date changes one time, do it again and it changes again. Just as easy as it sounds. They run at 18,000 bph and have a power reserve of about 45h. From what I know they all have hand winding too. (only some of the diver style earlier versions I know about might come without hand winding). You can read more about the 21 J calibre HERE. It also came with 23J and the top of the range 39 J Super Jet.

What else? Well… I guess it is a feeling that has to be experienced, owning such a marvel, winding it, listening to it, watching it… So, take your chance, you won’t be disappointed.

Citizen Jet Para Water Professional


I was and I still am intrigued by the fact that the lume on Citizen watches doesn’t seem to age like the one on Omega or Rolex or other collectable brands. In fact I lusted for an aged, yellow-brown lume for some time now, on a vintage Citizen and was not able to find a good one. They are either perfect green like new, or, on not well preserved pieces, dirty. It made no sense to me. How can I get a nice patina dial? Finally my dream came true with this awesome timepiece!

The Citizen Jet Para Water Professional

Inside the case back the model no reads: JTI30705I

This watch was made in 1962 soon after the introduction of the first water resistant Japanese watch: the Parawater. It also has the Professional label, a rare clasp, a Jet movement and an awesome case back engraving. This was an age when watches had a practical use and not the jewelry that they (sometimes) are today.

The case is made entirely in SS, it is about 37mm and has a simple dial, three hands and no date. The lug hols make changing the original SS bracelet changes so easy! In fact this is a watch that looks good no matter what strap you throw at it: nato, mesh, leather, even rubber. The winding crown is also SS and it is unsigned. At first sight it is very similar with the Parawater I told you about, but this one is not made for water use, but for aviation?. An indication of the link to the aviation is the Jet airplane engraving on the back and the Professional label on the dial. Also a Jet logo is printed on the dial too (Jet movement). In fact the dial has 12, 3, 6 and 9 printed, and the markings: “Citizen Jet, Para Water, Professional”. The hour markers are trapezoidal,  raised and polished. They are filled with (now) the beautifully aged luminous material and so are the matching dauphine hands. All things considered it is a beautiful, simple, balanced face that I like a lot! I have seen very few examples of this model and some of them have an arrow shaped hour hand and a thicker minute one with a flat tip.

The movement is the usual Jet movement with a circular swinging rotor. It runs at 18,000bph as all of them do. This one is the first one made, launched a few months earlier, in October 1961. My watch in made (3-4 months later) in March 1962. It is an automatic (hand winding also possible) with non hacking sweeping central seconds hand. It is called Citizen calibre 3010, Jet movement, and was the first movement that Citizen produced in relatively high numbers. The interesting fact about the rotor is that in earlier types it is marked “Automatic” rather than the usual “Autodater”. The date was added a year later, and so did the name “Autodater”.

And to add to the story… the clasp is marked: “Easy-O-Matic, Citizen Band, Pat.Pend. Stainless Steel” making it even more interesting if that was even possible. 🙂
