I will just call the Roger Dubuis BIG!
This RD was one of 3 tourbillon, perpetual, minute repeaters along with the AP Grand Complication and the PP5016. It was extremely funny to see the difference in size. Fernando has a side by side shot ofthe PP and the RD. So funny!
The RD is a really impressive watch. You dont wear to avoid being seen. I think the owner had to bring an extra bag to carry this in!
