What happens when you drop an exclusive and highly limited edition A. Lange & Sohne Tourbograph Pour le Merite into a vat of molten hot baguette cut diamonds? Well this special edition version of the watch for Dubail of course! Dubail is a luxury watch and jewelery store is Paris, and is blessed enough to have what just might be the world's most expensive new A. Lange & Sohne watch - limited edition of just one piece.

The Tourbograph Pour le Merite was outstanding enough, but this 'piece unique' takes the luxury to a different level by adding 201 diamonds on the case, and another 175 on the bracelet. There are over 40 carats of diamonds on this 41.2mm wide watch done in white gold.

Looking closely you can see that so many parts of the watch have diamonds in them. Even the crown and chronograph pushers. What is interesting about the watch, is that the inside of the watch is just as stunning as the outside. You can see it through the sapphire exhibition caseback. Although a diamond covered watch like this is of course gaudy, I think that it is as tastefully done as could have been. The watch itself has a manufacture made caliber L903.0 tourbillon movement, with a 30 minute chronograph and power reserve indicator. My recollection is that the movement alone takes about a year to make. The watch will be available at the Dubai store with a retail price of 1.2 million euros (or about $1.75 million).
