I think this is a really nice idea and something completely different. I can?t recall a dial like this before:

The pictured piece is a prototype and the strap is not the final choice.
Being a proto was apparent when flipping it over:

To explain: A couple of pieces on show are non-functional design models, produced in order to show how it looks like. Making all of them watches or even start a serial production would slow down the preparations for the SIHH fair very much, hence some are left with dummy movements.
