IWC Portuguese Perpetual Calendar Double Moonphase with the 18-karat white gold one and the 18-karat red gold version - replica IWC Portuguese Perpetual Calendar.
Large-sized case with the diameter of 44.2 mm and the thickness of 15.5 mm. The watch case is domed on both sides by convex sapphire crystals with antireflective coatings and it is constructed to resist water pressure up to 30 meters (100 feet). The case incorporates a fixed bezel and on the right side, there is a screw-in crown.
The moonphase indicator at the 12 o’clock position which shows its course and features the mirror images of the moon in the northern and the southern hemispheres deviates from the moon’s actual progress by just 12 seconds in each lunar period. In other words, it delivers perpetual calendar accuracy with the deviation of just one day every 577.5 years, which is quite amazing.
IWC-manufactured Caliber 51614 mechanical movement with Pellaton automatic winding system and a seven day power reserve. The imposing movement is built on 62 jewels and beats at 21,600 vibrations per hour. The mechanical perpetual calendar takes into account every leap day in the Gregorian calendar and requires only one adjustment at the end of February in 2100.
