DeWitt watches have introduced their new Haute Joaillerie collection which is meant to marry form with substance in the form of high-end watchmaking and diamonds and rubies. The three watches are the Differentiel, Mysterieux Squelette and Force Constante each with a tourbillon. All the gem-set parts of the case and buckle of Haute Joaillerie Tourbillon watches includes stones set along the caseband, bezel, lugs, crown and buckle.

The Tourbillon Differentiel was the winner of the Geneva Watchmaking Grand Prix in the innovation category and includes 151 diamonds totalling more than 17 carats. The movment is the handwinding caliber DW8002 with 24 jewels and the 18K white gold case measures 43mm X 12mm.

The Tourbillion Mysterieux Squelette features 141 diamonds with a total of over 17 carats. The movement is the handwinding caliber DW8001 with 19 jewels and the 18K white gold case measures 43mm X 14mm.

The Tourbillon Force Constante uses the handwinding caliber DW8003 movement with 25 jewels, beating at 21,600bph with a 72 hour power reserve. The 18K white gold case 18kt white gold measures 43mm X 12mm. It is accented with 151 rubies that have a total carat weight of more than 17.6 carats. Because all three models are such gorgeous pieces of art, I would be hard pressed to choose just one. But, if I had to choose, it would be the Mysterieux Squelette.
