Legibility is Key:

Is legibility your thing? Do you think having 57 complications would… complicate things? Vacheron Constantin doesn’t think so. Here’s what they had to say about it:

“Featuring a double dial, the Reference 57260 watch offers an elegant display with perfect readability … Considering the number of major complications on display, the front and back dials of the Reference 57260 watch rise to the challenge with a display that is exceptionally easy to read.” –source

Where can you buy a Reference 57260?

There is only one in the world. VC lists this timepiece as a one-of-a-kind custom-made piece, so you’ll have to wait for the current owner to put it up on eBay or something. No lowball offers!
