The examples you gave clearly show that full 60 second markers on a subdial can look very elegant indeed. You have thoroughly convinced me of that. I now think I overstated the case. I like the Blancpain and Breguet best. I also share your sentiment regarding the Roth design. Some of the other, rather odd, designs suffer from peculiarity, and accordingly, they'll certainly never be regarded as classics. They are merely fashionable and seasonal. They'll pass away when the next market researched model is churned out. To this extent, the Daytona is the classic chronograph par excellence (which I agree with). It is seen as the premier sport chronograph on the market and is the most desired and admired watch on the planet (which I disagree with). I also sincerely think that my particular Daytona model has the nicest looking subdials of the lot! While there are better watches than the Daytona (but at what price?!!!), including my wife's horribly expensive chocolate Deville, nevertheless, none of them have that classic status the Daytona enjoys. I therefore am inclined to think the best and most enduring design belongs to the Daytona, which includes the layout of the tri compax design and the layout of the seconds subdial in particular. On this I remain convinced. As I previously said, the design is as classical as it gets.
It's unfortunate, nay, very sad, that the Speedmaster doesn't enjoy a status has high as the Daytona. In fact, because of its historical significance, it deserves a higher status. However, Omega have only themselves to blame. They downgraded the movement from the 321 to the 861 and cheapened the name with low end Valjoux Speedmasters.
