IWC is very proud of one of their technological inventions which is the digital calendar. IWC applies the invention to Portugieser collection. People can see date and month directly from two oversize windows on the dials. These two windows are set in a symmetrical way. There are blue hands on the delicate dials, adding more colors to the whole image.
IWC Portugieser fake watches with silvering dials have been applied with many advanced technologies including perpetual calendar, large digital display, leap-year display, flyback chronograph functions. They are driven by calibre 89801, self-winding mechanical movements with 51 jewels and red gold rotors. The Swiss movements can save 68-hour power. The diameter of their platinum cases is 45mm. There are another two sub-dials set for chronograph functions.
The elegant IWC copy watches have transparent case backs, revealing the beauty of the running mechanisms. They have a daily waterproofness. The timepieces are introduced to celebrate the 75th anniversary of the birth of Potugieser collection. There are also other limited editions for fans to collect.
