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.
