    CYMA Cal. R.804.00 Movement Pics

    Hi guys

    Here are a few pics of the movement in my newly acquired CYMA Divingstar.

    Just wondering if anyone could give me any information on it of any kind?

    Also, any ideas how I could best go about dating this watch?







    Thanks for any info guys

    Russ

    Hi Russ. Looks like an ETA 2451. It's in very good condition.

    Ammm... is more modern than 2451, since in the picture the movement's tige is released by button and not a screw, as the 2451.
    Close enough and from same family but seems actually a 27xx, dunno exactly which, though.

    Edited: Actually is a ETA 2722R / 2724R / 2728R Movt (R variant for the ball bearing in the rotor)
    depending on what the movt has: date / date quickset / day, date quickset

    So, in all, a good auto watch from the 70s

    Regards

    A blast from the past! Thanks for providing the detailed information. Future Googlers owe you a debt of gratitude!

    "The watch has to be surrounded by a history.
    You need more than just a great design. You need to create an atmosphere around the product.
    Who is the company behind it? Why are they using this material?
    People need to be able to identify the watch with themselves. It's based on emotion." - Ralph Furter

    ...that's just my opinion and I've been wrong before and will be again and might be now!

    Notice the two polished circular pits under the balance. One would have read "2471", the other "ETA" in the clover leaf shield. Cyma, who at least at some stage in their history made their own calibres, some of them automatic, apparently wanted to mask the origin of their movement. Not unusual in the watch world: I have a Baume & Mercier with Buren microrotor movement with the "BAA" in the triangle eradicated.....
