IWC is updating its Da Vinci family in 2017, including a return to the real round case which popularized this line back in the 1980s. The Da Vinci Tourbillon Retrograde Chronograph Watch is the flagship model for the redesigned collection, which combines a flying tourbillon with hacking mechanism, a chronograph and a retrograde date.
The designers in the factory set the tourbillon cage on the initial fourth wheel whilst the small seconds sub-dial was stepped into a central seconds. The flying tourbillon makes a complete rotation every minute, thus meaning the tourbillon bridge can function well as a seconds hand too. To unite these three complications for the very first time, the replica IWC redesigned the model. 
You could notice that a fully fledged tourbillon was integrated to replace the small seconds counter at the 6 o’clock position. The hour and minute chronograph indications stay on the top of the dial at the 12 o’clock position. The chronograph with a flyback function can record elapsed-time intervals up to 11 hours and 59 minutes. In addition, the central chronograph seconds hand can measure stopped times with high precision up to 1/4-second. The chronograph can be set via two golden push-pieces set on either side of the crown. There is a retrograde date indication as well which describes a gentle arc on the left-hand side of the dial. The date hand jumps back to 1 after the 31st of the month automatically.
The pallet and escape wheel are manufactured from diamond-coated silicon which offers a decent 68 hours of power reserve when fully charged. This quite hard material has a good sliding property which could help reduce friction. It operates at the rapid frequency of 28,800 alternations per hour (4 Hz).
The fake IWC Da Vinci Tourbillon Retrograde Chronograph with this model is styled and sized to make a great impression on potential customers. The 18-carat red gold case measures 44mm in diameter and 17mm in thickness. The gorgeous case is shielded with sapphire crystals and constructed to offer water proof up to 30 meters (100 feet).
There is an arched sapphire glass from the front side, together with antireflective coating on both sides, while form the rear there is see-through sapphire-glass back which offers a look at the impeccable IWC-manufactured caliber with its solid red gold rotor.
The new Da Vinci Tourbillon Retrograde Chronograph replica watch comes with the movable horns which ensure that the Santoni alligator leather band fits perfectly on the wrist. The dark brown leather strap is secured with a red gold folding clasp.
