  1. I have looks to be a Vintage Time watch it has a silver band with a purple face and a blue sapphire on the minute hand. I’m trying to find out how old and how much it’s worth.

    I acquired an old citizen GN-4W-S. It has the following numbers on the back: 6101-915071 KT and 80502518. I am wanting to find any information I can about this watch.

    Your help is appreciated

      Hi Brandan, thanks for visiting my blog. I am not too familiar with the quartz models, other than the early ones, i.e. from the mid to late 1970s. Yours has the 6101 movement inside which isn’t from the 1970s as far as I know, but since it has an eight digit serial number (later ones had fewer digits) I think yours is most likely from May 1988. GN-4W-S is a case type code, indicating a water resistant design with a screw down back. Here’s a link to the relevant technical manual for the 6101 movement:

      Thanks for visiting my blog. Your watch has the 8200 movement inside, which was first produced in 1976. It became Citizen’s workhorse movement and remained in production for over 30 years. Because of this they can be difficult to date, but the way yours is marked suggests to me that it is a relatively early one. ‘4-280041’ is the case number and confirms that it is an 8200 model (4-28xxxx is a typical format for these), as is the model number (51-8093). The 8200 models are often marked with an ‘Eagle 7’ motif, a range that was introduced in the early 1980s. The first three figures in the serial number (005) give us the production date, which I reckon is May 1980. An 8 digit serial number is also indicative of the earlier models. There’s more info on the 8200 auto here: https://sweep-hand.org/2013/01/27/the-8200-movement-citizens-standard-auto/

    Hello, Love the blog and I would appreciate some help…..

    Recently purchased a vintage citizen “eagle 7” and I was wondering what date it was made. The number on the back is 4-039254k and I was having trouble understanding your charts as there is no 39th month lol. Any help is greatly appreciated 🙂

    Hi, would you give me information on the watch I got from my grandmother. I’m guessing it was exported from Japan.

    WPG
    Citizen
    6800
    4-681371 S
    4010937

    It’s a beautiful bracelet type women’s watch. Thanks for your advice!

      Hi Manami, thanks for visiting my blog, and apologies for my late reply. I’m afraid I can’t tell you very much about the 6800 movement in your watch since little information is available about women’s watches. As far as I know it’s a hand winding movement similar to the 6700 you can see here: http://www.ranfft.de/cgi-bin/bidfun-db.cgi?10&ranfft&0&2uswk&Citizen_6710. As you can see it was first made around 1980, so I think your watch is from around the same period and the serial number (4010937) suggests it was made in January 1984. Sorry I can’t tell you any more.

    Hi,
    I have a Citizen automatic 21 jewels on the back is written:
    Parameter citizen automatic
    C.G.P
    4-65O93OY
    20501131
      61-6524.
    I would appreciate you all if you can give me any information about this watch

    • sweephand says:

      Hi Randhu, thanks for visiting my blog, and apologies for my late reply. Your watch is from May 1972, and has the 6501 movement inside. This is a nice automatic movement, first made in 1971, running at 21,600 beats per hour and all of them had 21 jewels. ‘CGP’ is ‘Citizen Gold Plate’ so the case is gold tone. 4-650930 is the case number, which also indicates the movement inside, whilst 61-6524 is the model number and I believe yours has what is known as a ‘TV’ style case.
