DA VINCI TOURBILLON RETROGRADE CHRONOGRAPH

First IWC timepiece with a Chronograph, Tourbillon, Retrograde Date on the dial !

The creation integrates an ingenious system : The « Hacking Tourbillon »

In fact when you pull out the crown, two levers grasp the balance rim and stops it (the mechanism even stops the seconds display of the chronograph). The objective here is to be able to set the time with more accuracy as the caliber switches to a « pause » mode. The development had an additional challenge: The Friction. You might guess that pulling in/out the crown and its effect on the movement uses the components so IWC found the solution by producing the pallet and escapement wheel in diamond-coated silicon. Therefore, the problem was solved and the 68 hours of power reserve remains.

The overall design is Stunning!
The escapement wheel is wonderful to look at and obviously a major space was left to the « main show », the Tourbillon.
The Retrograde date is very interesting as its design is subtle, fine and very convenient. The different textures between the Chronograph counter and the dial is another great detail and the back remains wonderful with its skeleton rotor and high finishing quality.

With the « Hacking Tourbillon » system and a new set of mechanical propositions, the timepiece is part of our favourites of the SIHH 2017.
Our Hats off, IWC !
