I think it is NOT a requirement...

 

there was a discussion some years ago here on Purists about this very topic:


www.network54.com .

Furthermore, when you read the requirements of the Poinçon de Genève there is nothing mentioned about the column wheel. This might have changed due to recent revision of the requirement.

I will provide more information in a few weeks (months??? Oh my scarce free time...).

Best,
Magnus
