    Brand Identification (Goma)

    Is anyone familiar with a brand called Goma? Just bought a triple date on ebay and I know nothing about the brand. Nor can I find anything.





    (different case, same watch, and I assume movement.)

    Edit: All I have learned is they were a Jewelry company.

    I've narrowed the movement down to a Venus calibre 204.

    It is a Venus 203 EG. The 204 has moonphase.

    If this is your first triple date, congrats Actually congrats anyway, nice watch

    I personally find them addictive.

    Hmmm, I see the problem. Roland's page is inconsistent. If you look under the main description for the 203 and 204 it does indicate the 203 is moonphase and the 204 is triple date. But if you look under 'family' on the right hand side, it is the other way around with 203 being the triple date and 204 being the moonphase. I had a look around, and I cannot confirm from other internet sources which is correct.

    Looks like I will have to take mine apart again to find out.

    Better you than me. If I take my movement apart I wont have a watch any more. Unfortunately, none of my books have any mention of Venus movements. Let me what you find out.

    Re: Brand Identification (Goma)

    Just looked in my triple date and it is 100% marked as a Venus 203.

    But it is still not clear which is correct, as RR notes the 204 is sometimes marked as a 203.

    However the pages are still inconsistent.

    I will email RR and let him know.

    Re: Brand Identification (Goma)

    Hi ladies,

    among my movement catalogs there is only one that asigns the numbers
    203 and 204 to paricular features, the Flume K3. All others give no
    informations about the real features.

    So I'll not change the assignment in my archive as long as no genuine
    Venus data sheet with different assignment appears.

    Assuming that a derivative of a movement gets a higher number, the
    assignment is logical. The 204 is a 203 without moon phase. All parts for
    the fully equipped version are present: The lever to set the moon phase,
    the post for the disk, only the disk and its jumper are missing.

    I doubt that ever one of these movements was signed with 204, except
    late examples which cover all versions with the signature 180...204.

    Regards, Roland Ranfft

    Hi there,

    sorry there was an error in the family list, I didn't notice because it was correct in German.

    It is correct now:
    203: 11.5''', calendar, moon phase
    204: 11.5''', calendar

    Regards, Roland Ranfft
