2015 SIHH Novelties–IWC Portuguese 7 Days Automatic

Posted by Sung on February 27, 2015 in Uncategorized |

The most renown and most-demanded IWC Portuguese series welcomes its 75thanniversary, which is 3/4 century. This is the very year for IWC Portuguese, and most important year, so IWC got rid of the typical 50000 movement after for the first time after 2000, and rebuilds 52000 movement and applies it into the brand-new series. This year, Portuguese is the very year. In 2000, IWC launched a Portuguese 7 Day Automatic that gives a blow to the watch industry. This is a IWC-developed 50000 automatic winding movement whose Pellaton winding system and single barrel are highlighted. In the coming years, movement structure has been improved and until 2013 and 2014, some parts of the movement are replaced by ceramic. But in 2015, IWC changes type 50000 movement into a 52000 movement.

What is that new movement? We mentioned it before in our post. It is nothing but change the single barrel into double barrels, to get a better stability. Actually, the single barrel has been performed great in stability, and there is no sense doing it again. So you will see that the pendulum of the movement improve up to 28,800 times per hour. This is a change in quality, meaning that IWC Portuguese became a high-frequency watch and has the best performance on the stability. As we know, the oscillating frequency is closely connected with the energy of the barrel and that is easy to understand why IWC prefer the double barrels than the single barrel. As far as I can see, the watch with both high-frequency and long energy are quite rare, and IWC is walking in the frontier in this field, taking the lead. In addition, choosing what material is critical, so the automatic wheel is made of black ceramic and the rotor is made of white ceramic, or more precisely speaking, zirconia. Those changes will expand the lifespan of the movement. Or you can check theĀ replica swiss rolex for more choice and deals on your watches buying online.
