2017 IWC Da Vinci Tourbillon Retrograde Chronograph IW393101 has been the name of its innovative: this watch will be the classic Tourbillon, chronograph and reverse jump date on the combination of the dial. For the combination of these three functions, IWC watchmaker designed a new 89900-type self-movement.
The complex function of the tourbillon frame is moved to the bottom of the watch, thus omitting the upper deck. In addition, this time also equipped with high-tech connotation of the tourbillon stop function, which can watch the accuracy of the seconds to set. When the crown is pulled out, the two levers are engaged with the outer edge of the balance wheel as a clamp, and thus the balance wheel, the wheel train system and the pointer mechanism are paused. Thanks to the new geometry of the fork and escapement wheel and the diamond shell technology applied, the 68-hour power reserve, which was initially full of chains, was able to be maintained despite the additional complexity of the watch. The fork and escapement wheel is made of diamond-coated silicon material, and its particularly hard surface has good sliding performance, which reduces friction and resistance, thereby helping to maintain the initial power reserve. The chronograph function is set at the top of the "12 o'clock" position and the measurement time in 11 hours and 59 minutes can be read as if it were a normal time. With the central second hand to read the measured time, accurate to a quarter of a second.
In addition to chronograph and tourbillon, the third complex function is located on the left side of the dial in the reverse jump date display. The date pointer is advanced in the arc from the first day of the month to the 31st day and jumps back to the starting point at the end of the end, thereby displaying the current date. In less than 31 days of the month or when the watch is not used for a long time, you can quickly push through the crown and set the date. Compared with the classic date window, this kind of pointer display can bring different feelings for the wearer.
Watch the noble gold gold case plus gold button and the table ears to make the appearance of the watch introverted symmetry. Thanks to the mobile lugs, equipped with 18K red gold folding clasp dark brown Santoni crocodile leather strap can be perfectly attached to the wrist.
