I’ve just uploaded the latest version of the Movement Table, moving from v5.2 to v6.0 – access it via the blogroll on the right of the page.
I’ve now included the divers in the dial markings column – these were previously incomplete until I’d done my research for the Divers Page. And besides one or two other minor amendments I have also been able to include the 7250 and 7750 movements, which are chronometer grade models in the Leopard line, with 31 jewels – see this thread on the SCWF for information:
http://www.thewatchsite.com/index.php/topic,39984.msg267775.html#msg267775
Following help from ‘Andy’ via his comments on this blog I’ve also added a note to the production date section at the end of the table, to reference a different type of serial number.
Sweephand's Vintage Citizen Watch Blog 
Gday Steven,
Was wondering if you could help me ID a watch. Ostensibly 21J with round golden dial. Green glow-in-the-dark dots every five minutes. It has squares at 6 and 9, two squares at 12 and day/date at 3.
Case back is as follows:
CITIZEN WATCH CO
WATER RESIST
STAINLESS
4-038860SMK
70702320
GN-4W-S
JAPAN
Cheers mate. Any help would be gratefully received.

Hi Dave – thanks for visiting my blog. You have an automatic from July 1987, with the 8200, 21 jewel movement that Citizen introduced in 1976. The movement has been used, and developed, for 30 years or so – it was Citizen’s ‘workhorse’ auto and in good condition it is very reliable and can keep very good time. Typically in the 1980s the dials have a stylized eagle logo, with ‘7’ in the centre and these are known as Eagle 7’s, a competitor to Seiko’s ‘5’ range. The 8200 runs at 21,600 beats per hour and can be hand wound as well, which is useful to get the watch up and running quickly when it has wound down. Here’s a link to the relevant instruction manual: http://www.citizen.com.hk/upload/instruction_manual/8200__E.pdf
Hope this helps,
Stephen
Oh ripper. You have decribed it perfectly. Except for the eagle and 7. Possibly a new dial? I don’t know. It was a cheapy from India.
Was extremely reliable for a number of years, but now has a rattle and is difficult to start up. Any idea what this could be?
Ah, if from India it is probably a re-painted dial. Sounds like a loose rotor – can you hand wind it? If the rotor is loose it could mean that the screw threads have worn away – you need to get the back off and have a look to be sure whether this is the problem.

Hi Steven
I have an old women’s watch, i will copy what it writes on its backcase:
BL
CITIZEN
4-66036TA
PARAWATER
2030310
64-1537
GN-4-S
and its frontplate:
CITIZEN
AUTOMATIC
28800
it has a day/date window
Can you help me to ID this watch?
Cheers Levi
Hi Levi, thanks for visiting my blog. I can indeed help id your watch 🙂 You have a Cosmostar V2, which was produced in the early 1970s using the very nice high beat (28,800 eats per hour) 6600 / 6601 movement. They have either 17 or 21 jewels, and can run very accurately and reliably even with little or no servicing. The case material code (BL) suggests yours has a black coated case – is that correct?
4-66036 (does it have one more number in it, they are usually in the format of 4-xxxxxx?) is the case number, which also helps identify the movement. 64-1537 is the model number, which is not so helpful. GN-4-S is the case type, meaning it is a waterproof design with a screw on back. 2030310 is the serial number, and the first three numbers gives us the production date. Since these were only made in the 1970s, yours is from March 1972.
Stephen
Thank you for the answer and I have a question about this watch
Its glass is very scratched it can be replaced?
Here is some photos of the watch:

Thanks again
Levi
You’re welcome Levi 🙂 I’m afraid original parts for Citizen’s older watches are very hard to find. The part number for your watch crystal is 54-50540 – I’ve checked a couple of suppliers but no joy I’m afraid. You could ask a good watchmaker to find an alternative – Jules Borel, a supplier in the USA lists an alternative for example.
Thanks for the pics – it is a nice watch, and I hope you can get a new crystal for it.
Stephen
Helllo there, I was giving my Grandfathers watch after he passed and was hoping you could shed some light on it for me it’s a citizen model gn-4w-s and the serial # is 50690677. It’s also has cq stamped on the inside face under the glass, looks to be 70s to late 80s, thank you in advance if your able to help.
Hi Janet – thanks for visiting my blog. I’m afraid I don’t know the quartz models so well, but I would think yours is from 1985. Stephen
Hi Stephen,
Could you please help identify my watch. Nothing written on the dial except Citizen under 12 marker and 21 jewels on top of 6 marker. It has a date window on 3.
On back case written:
Water resistant
4-168011 SM
63-1591
Thanks
Migo
Hi Migo – I believe your watch is from the mid-1970s, and has an 1810 ‘Homer’ movement. This is the date version of the 02 Homer, a movement first produced in 1960 and made right through to 1980 or so. This model has no serial number unfortunately, so we can’t date it exactly. the ’63’ prefix to the model number is typical of Homer models. The use of water ‘resistant’ rather then ‘proof’ means it must be later than the early 1970s. You can find more on the ‘Homer’ movements by searching my blog and taking a look at the 02/Homer Family Tree.
Stephen
Hi again Stephen. Thank you for your fast reply and the information.
Just curious, how do you know the cal is 1810? I just check and find a very small code and yes it says 1810.
Thanks again.
You’re welcome Migo. The indicators for the movement type are that the ’63’ part of the model number was used for Homer movements, and so too were case numbers with 4-16xxxx. Since the watch has a date complication it must be the 1810, rather than the 02 which has no date. Stephen
Could you help me I found this watch on a trail in Tn. Some years back and put it away in a box I took it out to put a battery. Citizen watch: 3220. S 04573 SMW. 8043657 GN4-5-5. Thanks for your help.
Hi Ike, thanks for visiting my blog. I’m afraid that your watch is more recent than the period I look at, so I can’t be of much help. For information here’s the relevant technical manual: http://www.thewatchsite.com/files/Citizen%20Technical%20Manuals/3220.pdf
Stephen
It’s 2020 and I guess I’m pushing my luck here but I was hoping you could help me identify one of my dad’s watches.
The reading on the back says

Also this is a fantastic blog. You have a lot of history documented here over the years !
Hi Sulaisha, thanks for visiting my blog and for your kind comment. It would be helpful if you could send photos of the dial and case back – I will email you direct since you can’t post them here directly. Stephen
Hi its been so interesting reading your blog and everyone’s stories, I am hoping you can help me also identify my watch Citizen watch Co, W. R 5BAR, St Steel, F510-so39568 cwt, serial no 6 n0713, GN – 4-s¬9, on front screen says wicca citizen, I appreciate any information you can give me, many thanks
Hi Claire, thanks for visiting my blog, and good to see you have found it interesting. Your watch is a relatively recent quartz, so I’m afraid I don’t know much about it other than what I can get from the case back information you have provided. F510 refers to the movement, which I understand is a chronograph with hour, minute and second counters. The ‘WICCA’ sub-brand was used for both men’s and women’s watches. ‘F510-so39568’ is the model/case number, but I couldn’t find an example on the internet – ‘cwt’ is probably a factory code. GN-4S-9 is the case type code, indicating a water resistant design. The serial number usually helps to give a production date, but I don’t know when these were made, so it could be November 1996 or 2006. As far as I can determine the 510 movement is not one of the solar powered eco-drive range. Here’s a link to the 510 instruction manual: https://www.manualslib.com/manual/784402/Citizen-510.html#manual

Hi Mark, thanks for visiting my blog. Your watch is a little too recent for me since my collection and reference material run to around 1980 at the latest. The 3801 is a quartz movement, usually marked ‘Crystron’ I think. My best guess is that it is from the mid to late 1980s, so using the first three figured in the serial number, yours is from October 1986 (610). ‘3801-987861′ is the case number, which helpfully tells us which movement is inside. ’35-8622’ is the model number and ‘GN-4W-S’ is the case type code, indicating a water resistant design. Stephen
Thank you! This is very helpful. I appreciate such a thorough response.
You’re welcome 🙂
