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.

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.

According to Dr. Ranfft's Web site the 203 has the moonphase. Thanks, this is my second triple date. My other triple date has a moonphase.

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.

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
