I think Chopard's Tribute watch is worth every penny that the company is asking for it...
Anyone can see the huge difference between the two. The Chopard's case is of precious metal, the locking mechanism is more complex, and obviously the movement required a lot more work. More importantly the premium in the price is used to support the development of the new caliber which will be put to good use by all the new watchmaking students. I think that in itself is a worthy cause.
I guess the 450X difference depends on the eye of the beholder.
It is the otherway around in my humble opinion...the brands who use similar movements and classify the pieces as haute horology should be ashamed.
Micromechanics and engineering principles are the same around the world...I hope to see real Chinese Haute Horology soon.
Best, Mike
