I am really fascinated by your analysis. The Daytona is not a fair comparison perhaps but, to give you more context, I was wearing it on the day and the price for the bicolor daytona is lower than the Tonda GT. One could argue that the tonda movement is more special but, given that vaucher provides these movement to Hermes and other companies I am not entirely sure if this is true beside the different decorations.
I think your choice makes sense and I will try to Tonda GT. I was looking for a steel sport watch with at least 100Mt water resisistance and that doesn't draw too much attention (so not a rolex, AP or Patek which I already own).
Frankly the date in the Tondagraph doesn't bother me so much. I am not sure about the thickness and the bracelet. Something just doesn't sing as love at first sight.
The PF is much more slender and I would compare it with the AP, Chopard, Patek and the likes. Still I think the pricing is not very competitive. I totally agree that the PF is father away from the daytona. Much slimmer and reminds me more of the other famous brands.
Luckily summer is still far away so I have more time to ponder. It wasn't love at first sight/impulse buy. May be is a good thing so I can give some of the watches I already own and at the bank a fair chance
