Perfect Password: Iwc Da Vinci Watch Series (Below)

The theme of this year’s IWC is finally back to the DaVinci series. In addition to the automatic 40 mm and two 36 mm women’s watches already introduced in the new Da Vinci series, it is worth noting that it also introduced a perpetual calendar chronograph watch and a tourbillon retrograde chronograph watch, two equipped with Complicated by the first self-made chronograph caliber 89360, a new movement that extends the movement, and a new Da Vinci chronograph equipped with a caliber 89360. The perpetual calendar chronograph with the 89630 movement is a tribute to the classic perpetual calendar mechanism invented by Kurt Klaus, which has attracted special attention.

New version of homemade chronograph-Da Vinci chronograph ‘Lawrence Sports Charity Foundation’ Special Edition
   The two complication watches featured by IWC this year are extensions based on the self-made chronograph movement 89360 introduced by the brand in 2007. Before officially introducing the two complication works, we first use the Da Vinci chronograph. New work to review some of the functional characteristics of the 89360 movement. In the past, IWC relied heavily on the Valjoux 7750 chronograph movement, including the perpetual calendar movement 52710 developed by watchmaker Kurt Klaus in the 1985 perpetual calendar chronograph, which is also based on the 7750. In order to further expand the layout of the homemade movement, the launch of the barrel-shaped Da Vinci in 2007 also launched the 89360 homemade chronograph movement. Features are column guide vertical clutch design, flyback timing function, and the 60-minute and 12-hour counter at the 12 o’clock position as a single dial display, while using the new Pellaton (Woodpecker) winding The system to improve the efficiency of the chain. This self-made chronograph movement will later become a universal chronograph movement under IWC.

   In the same year that IWC changed the Da Vinci series to a barrel shape in 2007, IWC launched the first Da Vinci chronograph equipped with the 89360 movement. This year’s new work is the first to incorporate the 89360 movement in a round case. The Da Vinci chronograph is launched in a special edition of the ‘Lawrence Sports Charity Foundation’. According to the previous case, the back cover engraved the award-winning works in the annual drawing competition organized by the Lawrence Foundation, which has a different meaning.
Leap forward in technology-Da Vinci Perpetual Calendar Chronograph
   In the year IWC launched the new-generation self-made chronograph movement 89360 in 2007, watchmaker Kurt Klaus already revealed in an interview with the media that IWC will eventually replace this self-made chronograph movement with the 7750 movement. And integration with the perpetual calendar module he designed is tantamount to predicting this 89630 with perpetual calendar and chronograph function. We waited for 10 years for this prediction, and finally let us wait for the official launch of this most symbolic Da Vinci perpetual calendar chronograph watch.

   The new 89630 movement uses the same perpetual calendar module as the 52610, so it has the design features such as the moon phase profit and loss display at 12 o’clock and the four-digit year display at 7 o’clock. However, the most characteristic hour and minute chronograph small plate of the 89360 movement is located at 12 o’clock. The moon phase profit and loss display may not be taken into account in the initial design. Therefore, when integrating with the master calendar module of Kurt Klaus, it is most necessary The key to the breakthrough technology is that the moon phase profit and loss display of this module overlaps with the chronograph disk of the 89360 movement. Therefore, the two functional components must be redesigned to integrate. The technical difficulty surpasses the 52610 movement developed by Master Kurt Klaus. As for another functional feature of 52610, the four-digit year display is faithfully retained. The chronograph and moon phases at 12 o’clock are small dark blue dials filled with white gold particles like a starry night sky, quietly supporting the bright moonlight of gold or silver. The new Da Vinci Perpetual Calendar Chronograph is available this year in two versions of 18K rose gold and stainless steel, each with a silver-plated dial and a limestone dial.
New feature combination-Da Vinci Tourbillon Retrograde Chronograph
   This is another complex function developed based on 89360 chronograph movement. Unlike the perpetual calendar chronograph which pays tribute to the classics of the master, the 89900 movement combines the design of chronograph, tourbillon and retrograde date. Is a new combination of features that first appeared in IWC. It is worth mentioning that the tourbillon equipped here has a stop-seconds device. When the user pulls out the crown, it will engage the outer edge of the balance wheel like a clamp through two control levers to stop the operation of the stopper. You can make precise time adjustments right away.

   This feature is no stranger to watch fans. In the past few years, Lange and Montblanc have also launched products with the same function. However, IWC’s 89900 has a vibration frequency of 28,800 vps (L042.1 from Lange and 21,600 vps from Montblanc’s MB 29.21). In order to achieve the stop-second function of the high-speed tourbillon, IWC specially made the tourbillon escapement fork in silicon. With the escape wheel and diamond-plated surface treatment, the configuration of these two parts is adjusted at the same time, which can increase the strength of the parts and reduce friction. In this way, not only can the impact of these two parts be momentarily stopped during high-speed operation, but also the energy loss of the tourbillon can be reduced, and the power reserve can be maintained at 68 hours, which is considered to be functional. A big highlight.
