In 9 o’clock, you’ve got the sub-dial that indicates daily, and at 3 o’clock you’ve the sub-dials that reveal the date and power reserve. At 6 o’clock, there’s a month indicator and moon phase screen, and to the left of it at around 8 o’clock you’ve the entire year indicator. Finally, there is the flying tourbillon that makes a single turning every second at 12 o’clock. The motion inside is your self-winding Iwc Watch Kaskus Replica caliber 51950, which relies upon the Caliber 51900 found in IWC’s additional tourbillon watches such as the Portugieser Tourbillon Mystère Rétrograde but with the innovative 82-part endless calendar module developed by Kurt Klaus. This movement also features IWC’s Pellaton winding system also has a generous power book of 168 hours, or 7 days. It is visible through a sapphire display caseback and comes with a special commemorative 18k gold rotor.The additional tourbillon watch that IWC has especially prepared for its 150th anniversary would be the Portugieser Constant-Force Tourbillon Edition “150 decades.” This comes in a slightly larger 46mm wide Portugieser style situation and is only accessible platinum. Like the earlier Portugieser Perpetual Calendar Tourbillon Edition “150 Years,” this view also offers heat-treated blue hour and minute hands. This is an updated version of past Constant-Force Tourbillon watches — Portugieser along with other versions — coupled with the “perpetual moon phase display. At 1 o’clock there’s a moon phase display that only needs to be adjusted by means of a day after 577.5 years. Ultimately, we have the highlight of this opinion, the large tourbillon with a constant-force mechanism which delivers power in impulses to the escapement. In theory, this should improve the chronometric performance of the motion.
The Ingenieur Perpetual Calendar Digital Date-Month is the flagship of the Ingenieur family. The design is inspired by the very first Ingenieur models and features a simple round case and polished bezel. The perpetual calendar with large digital date and month displays, which can be easily set using the crown, recognizes the different lengths of the months and takes into account the leap day every 4 years. The IWC-manufactured 89801-calibre movement also features a chronograph function. This timepiece has a 45-millimetre case made from 18-carat red gold, a silver-plated dial, black hands and a black alligator leather strap, and is limited to 100 watches.
