A 46mm is indeed a size that is not as small as 40mm.
Most remarkable watches that contains uber high horology are big show peaces.
That is why i skip the IWC Pall Weber 150 years edition. No constant forse or other exotic things, but the big size.
For this reason my FC810 with the remarkable monolithic oscillator keep the watch usable.
Fingers cross that GP comes with a smaller watch with a constant forse escapment.
Albeit, it is a stunning watch.
