A special place among my favorite Citizen movements is reserved for the Jet ones. And this one has the last of the Jets Citizen ever made. My watch was made in September 1966 and Citizen produced these movements up to about 1967. The last JET is the day-date Auto Dater Seven.
As you can see, it is in perfect, NOS condition, with price tag and booklet. The writing on the paper is in Japanese only. The day wheel is written in Japanese so, it is safe to conclude that, the watch was intended for JDM (Japan domestic market). The entire case as well as the bracelet, are made of beautifully finished stainless steel. The crystal is acrylic. and has a date magnifier.
The style of the watch is elegant, with a fluted bezel, simple silver dial with a sunburst effect. There is no luminous material on the dial or hands. The frontal part of the case is brushed, and all the rest is polished. The bracelet is also finished with a nice combination of polished and brushed surfaces. As I mentioned before, it is a day-date. That means that in addition to showing the date (at 3 o’clock), it also displays the day of the week (at 12). The day is in Japanese only, printed in black with red for Sundays. All the hour markers, the day and date frame and the Seven logo are applied.
The crown is used for winding the watch (although it is an automatic it can be winded by hand) and setting the time in the first position. The day changes by advancing the hands passing midnight. The date changes by pulling the crown. One pull of the crown will advance the day of the week one time. The crown get back to first position by it’s own due to a spring. Pulling it again, will change the day one more time. This system was named by Citizen “Easy Change”. What can I say, it is easy indeed.
The movement, is the last Jet, calibre 4102. It has 25 Jewels and beats at 18,800 bph. Beautiful!

As we were discussing, my search is for an Alarm/Date with fluted bezel and a black dial. I would consider silver or gold dials as well. Condition is important. I’d like NOS or as close as possible, with sharp flutes and edges. Love your work here. Thank you.
Thank you for your message. I will let you know if and when I will find a nice one.
