Iwc portuguese perpetual calendar limited edition 2010
This timepice has captured my heart with the gorgeous dial inn dark blue when I first saw it! And I am talking about the IWC Portuguese Perpetual Calendar in limited edition, which the renowned watchmaker IWC presented in the year 2010.
This Perpetual Calendar is surely a remarkable piece of micro engineering. Comprising several hundred parts, a perpetual calendar module quite literally counts the days, taking into account the variations of days in each month. This is a watchmaking complication so intelligent that it recognises leap years, one so precise that if it is maintained it will not need adjustment until March 1st 2100 – and only then because this will be a secular year and not, as ruled by the Gregorian calendar, be a leap year.
This latest Portuguese Perpetual Calendar has been given a tasty colourway, a rich blue dial combined with an 18 carat rose gold case.
Besides, it features a slightly smaller 42.3mm case, which, yet, has been just big enough to accommodate the generously proportioned IWC Calibre 51613 with Albert Pellaton’s winding system in this case, capable of a 7-day power reserve, mechanically restricted to ensure high precision.
This is a great watch which can tell you everything you need to know -- time, date, day, month, year and what the moon is doing. Moreover, it meanwhile manages to look handsome and elegant.
Presented on a black alligator strap, the IWC Portuguese Perpetual Calendar 2010 is in Limited Edition of only 100 pieces.
