Family Trees


The Movement Table provides a time line of Citizen’s vintage watches, listed by model name and in chronological order, together with key information as far as is known about each one. However, it is also interesting to see at a glance how base movements were used not only for a particular model, but also for other models and over time.

To do this a ‘family tree’ is useful, where the base movement is shown along with the original model it was used in, but adding as well the other models where that base caliber was used.  Sometimes there is a wide variety of models which at first glance may not appear to be closely related, as is well demonstrated for example in the 02 ‘Homer’ family. Links to the Family Trees can be found at the bottom of this page.

I hope the trees are fairly self-explanatory, with the base movement / model shown at the top. Each tree then branches downwards, colour coded to see the development lines. In the box for each version of the movement I show the year of first production, jewel count and any model variants, plus any specially noteworthy points.

At the bottom of the tree is a box showing common attributes for all models.

      Hi Shaun, thanks for visiting my blog. I’m afraid I’m not too familiar with the more recent quartz movements and models so I can’t be too much help. Yours uses the 3630 movement, but I don’t know when that was first produced. Looking at a few pics on the internet, it looks to me to be from the 1990s. If so yours is from May 1995 (‘505′ at the start of the serial number). ’36-4916’ is the model number, ‘3630-891309’ is the case number which also provides the movement number. ‘GN-4-S’ is the case type, indicating a water resistant design.

      Sorry I can’t give you any more info,
      Stephen

    Thank you very much,

      Hi Alin, thanks for visiting my blog. You have an 8200 Eagle 7 automatic watch, which I believe is from July 1989 (see first three digits of the serial number).

      • Alin says:

        Thank you very much Stephen, almost the same year when I was born, I’m in august 88 🙂

        Keep doing a great work on this blog!

    Hi,

    I found your blog while looking for some info on an Eagle 7 I recently bought.

    If I can send you a few pictures somehow I wonder if you could help me identify its authenticity and age.

    • sweephand says:

      Hi Joe – thanks for visiting my blog. Email sent 🙂

        Hi Joe – thanks for the photos:


        Looks like an all original 8200 Eagle 7 to me – there’s more info on the movement here: https://sweep-hand.org/2013/01/27/the-8200-movement-citizens-standard-auto/

        The Eagle 7 line was launched around 1980, and the serial number on yours gives a production date of August 1982, so it’s a relatively early Eagle 7. The 8 digit serial number is typical for that date and the rotor on the movement is also an early type. Btw it’s still possible to get an original replacement glass for this model.

        • Joe says:

          That is great info, thank you very much. It turns out that the watch is just a few months younger than me.

          I hoped that it was genuine but I couldn’t find a single other one with that same dial to compare it to.

          I am still waiting for delivery of the watch so I don’t know exactly what state it is in, only that it is not working. If you look closely you can see the second hand is loose inside the case.

          I’m hoping to get it working and restored to its former glory so I’m glad the glass is available. Do you have any idea where I can get one? I’ve searched online and can’t find anything.

  5. Robert says:

    Hi hoping you can help me identify this watch and maybe point me in the direction of some parts it is my first watch I was given in 1975 and I would like to get it repaired and working again

    Numbers on it are 2520. 4-200047 mm and 74 63- 8552

    • sweephand says:

      Hi Robert, thanks for visiting my blog. Your watch has a 2520 movement inside, which is a hand winding model from the mid-1970s. I think the most likely source for parts would be a ‘donor’ watch since parts are very difficult to find. Has the watch been looked at by a good watchmaker? Sometimes movements just need a thorough service – disassembly, clean and oil – and they then run well again. Or are you looking for specific parts? Stephen

      • Robert Chad says:

        thanks for your response i haven’t had anyone look at it yet the glass is broken and the second hand is missing i think it may have had something sat on top of it over the years i can still wind it but it doesn’t work will see if i can find a watchmaker in my area

    Hi, I’m currently looking at this watch on eBay: http://www.ebay.co.uk/itm/GENUINE-VINTAGE-JAPAN-MADE-CITIZEN-DATE-AUTOMATIC-MENS-WRIST-WATCH-JO-5038-/191899614277?hash=item2cae1bbc45%3Ag%3AAewAAOSwzJ5XZFOR

    I’m not necessarily looking for the highest quality watch, but I would like to know if it’s the genuine article. Any idea?

    • sweephand says:

      Hi Dan, thanks for visiting my blog. The watch has been re-dialled. The 8210 movement and case look to be original, although the case has probably been heavily polished. The quality of the dial and date window is not too good. ‘JAPAN MADE’ was not used on original pieces, and there should be a dial code printed below the 6 o’clock marker.
      Stephen

      • Dan says:

        Thanks for the comments. I suspected that it would be too good to be true at that price!

        • sweephand says:

          You’re welcome Dan – you should be able to find an original 8200 auto for a decent price. One of the best indicators of an original dial is the dial code. These are usually just below the 6 o’clock marker, and typically start with JAPAN (not ‘Japan Made’) then the movement number followed by a dash (‘JAPAN 8200-‘) and then the specific numerical.

    Hi,
    can you please help, i was left a citizen watch a few years ago but cant seem to find anything simular online or any info on it. It doesn’t seem to appear on the 52 family tree.., so i am assuming its in the custom range ?

    4-520543 TA
    61-5579
    90600120

    The watch has a black dial face inside a stainless steel setting. It also has chevrolet south africa on dial face.

    Thank you in advance,
    Alfie

    • sweephand says:

      Hi Alfie, thanks for visiting my blog. Your watch is an export version of one of the Crystal Seven models that Citizen first made in the mid 1960s. Their export models usually didn’t have the model name on the dial so yours is more simply marked, but with the Chevrolet logo added, so it was a special order for that company in South Africa. There is a 21 jewel 5270 movement inside, one of the extensive 52 movement family – 52 movements have day and date displays, but other versions were made with date only. 61-5579 is the model number, whilst I think the case number is actually 4-520548. These are good quality movement running at 18,000 beats per hour, and were a very successful range. The Crystal Sevens were the first Citizen watches to use hardened mineral glass, which gave them their name. The first three digits in the serial number gives us the production date, which is June 1969. Stephen

    • sweephand says:

      Hi Dennis, thanks for visiting my blog. Your watch is a quartz model so I’m afraid I don’t have much information. I would think your watch is from 1991 but I can’t be sure. 5930 is the model number, and indicates that there is a 5930 movement inside. Arrow pointing to 9 shows where the case back can be prised off, i.e. the 9 o’clock position.

  9. Hello. I am so happy I came across your blog. Would you be so kind to tell me the year (or any other info, since I have none) of my Citizen 7. The numbers on the case are as follows:
    4-063554 RC
    10701775
    71-2639
    Thank you in advance!

    • sweephand says:

      Hi Hrvoje, thanks for visiting my blog. Your watch is an ‘Eagle 7’ automatic, with the 8200 movement inside. This movement was first made around 1976, and was in production for over 30 years. They can be difficult to date as a result. The Eagle 7 line was first produced in the early 1980s, and again they were made for a long time, certainly into the 1990s. The eight figure serial number suggests it’s an earlier one so I would say it is from July 1981. Here’s a bit more info on the movement: https://sweep-hand.org/2013/01/27/the-8200-movement-citizens-standard-auto/

      Hi Ruslan, thanks for visiting my blog, and apologies for my slow reply. Your watch is one of the Eagle 7 models, which uses the 8200 automatic movement. This movement was first produced around 1976, and was produced for over 30 years, so it can be hard to determine when they were made. The Eagle 7’s were first sold in the 1980s, and were made into the 1990s, and maybe even later than that. However, the case back markings on yours look to me to be from the 1980s. The case number – 4-063554 – and the model number – 71-2639 – are consistent with the period. The first three figures of the serial number, indicate the production date. Since it starts with ‘0’ then I think it most likely from October 1990. Stephen
