I thought after last week’s Crystal Seven, and my mention of the ‘Seven’ name being used on autodaters and a hand winding watch, that I’d follow this week with that hand winding model. Rather than ‘seven’ being part of the model name, this one is uniquely called the ‘Citizen Seven’.
First produced in 1964, the Seven uses the 4000 movement, only seen in this model and one other – the Young Date – with 23 jewels.
As far as I can determine, two models were produced – the relevant ‘museum’ book shows this one, which was also made in a gold plated case:
In my view this version is not one of Citizen’s most memorable designs, however the other model, and the one I have in my collection has a much more pleasing look, and shares the blue applied ‘7’ logo with the Seven Autodaters:
The shield shaped day window, with wheel printed in both English and Kanji, is unique to this model, as is the printing font used:
The name and font style are repeated on the on the case back:
Made in April 1966, the back is marked with an ‘X’ – this may refer to this being a front opening case. As a result I can’t post a picture of the movement in this one.
The day is a ‘semi’ quickset by winding back and forth between 12 and 9, whilst the quickset date is changed by pulling the crown in and out at the second click. This also means that the hands are moved by pulling the crown out just one click. The downside to this design is that it is possible to accidentally advance the date if you want to adjust the hands and pull the crown out a little too vigorously!
The crystal is thick glass, and all models are rated at 40m water resistance, and run at 18,000 beats per hour. When new these (at least the model shown in the book) cost nearly JPY9,000.
