Hi,
Thank your for your comments.
When you state that the Gyro 1 or 2 fall short compared to Greubel and Forsey, I understand that you are just comparing the design of the tourbillon cage. Still the technical differences ask for a different design!
In fact I don't think we should compare the Gyro and the Greubel and Forsey pieces as they don' t have chosen the same technical ways, don't seem to have the same ambition and so don't have the same constraints!
Cheers
