and a Lange 1815 will still be thicker than your Patek 5712. MB&F watches are not quite for daily wear but they do have that wow factor and are definitely conversation pieces. I had a LM101 once upon a time but the thickness drove me mad!
And patrick_y not having enough funds to buy a MB&F is something that does not compute!
Now that you have at least one MB&F music machine, you need a watch to match!
