"I appreciate the effort" is all that we owe Vacheron Constantin for this creation.
Vacheron Constantin can't give a whole VC movement with high finishing and a Geneva Seal at this price point. Imagine the betrayal their former customers would feel if Vacheron Constantin sold a watch with a movement of the caliber you're expecting at that price... The FIFTYSIX Day Date model which does have a VC movement costs around 17000 CHF in steel. Here you're getting a 100% VC watch. That's probably more up your ally.
No... This is a reasonable action by Vacheron Constantin, they made an exquisite timepiece, albeit one with a movement that was "modified by Vacheron Constantin."
Kind of like my favorite car, the Rolls Royce Wraith. The Wraith's V12 engine is supplied by BMW, another subsidiary in the BMW Group. Rolls Royce does modify it to suit its own purposes and adapt it to better suit the character of a Rolls Royce, but in essence, it's almost identical to the BMW engine. And I don't fault Rolls Royce for doing that. And I applaud Rolls Royce for making the major modifications to adapt the engine to their platform. We both recognize the effort!
