First, let us turn to the Portugieser Eternal Calendar. For a long time, "precision" has been the paramount principle in horology. However, in the past, references to precision typically pertained to the accuracy of hours, minutes, and seconds; rarely did manufacturers extend this level of precision to complex complications. IWC has pioneered a new path: by employing an innovative, proprietary reduction gear system, the brand has elevated the precision of a complex function—the moon phase display—to unprecedented heights, creating the most accurate moon phase timepiece in history. The IWC Portugieser Eternal Calendar features a 44mm platinum case. Set against a silver dial, its various complications are arranged in perfect order, with the moon phase display positioned at 12 o'clock. According to the brand, the watch's moon phase mechanism is theoretically accurate to within one day of the actual lunar orbit—a deviation that would take 45,361,055 years to accumulate. On the strength of this achievement, the timepiece earned certification from Guinness World Records and claimed the highest honor at the 2024 Grand Prix d'Horlogerie de Genève (GPHG): the "Aiguille d'Or" (Golden Hand) award.
Achieving such extraordinary precision would be impossible without the Calibre IW52640 that powers this timepiece. Its unique distinction lies in its ability to mechanically interpret the irregular structure of the Gregorian calendar, automatically recognizing months with 30 or 31 days (including the unique case of February) as well as leap years. This movement is a modification of the Calibre IW52010, retaining the same oscillation frequency of 28,800 vibrations per hour and a power reserve of 168 hours. Next, we examine the Big Pilot’s Watch Shock Absorber XPL Skeleton Tourbillon. Building upon its predecessor's shock-absorbing mechanism, this new model incorporates a skeletonized tourbillon structure, pushing the boundaries of integration and precision to new levels. IWC’s patented shock-absorption protection system dates back to 2021. The inaugural model (Ref. IW357201) featured a 44mm titanium case and was limited to an annual production run of just 10 pieces. Now, this new iteration—enhanced by the addition of a skeletonized tourbillon—brings the total limited edition production run for this series to 100 pieces.Repwatcheaprice - Luxury replica Breitling Navitimer price, Cheap Watches For Men And Women.
