IWC Portuguese Grande Complication Watch

in Basel 2010 | Saturday, February 20. 2010

IWC has a huge year planned for 2010 with nine official introductions, the most impressive of these being the IWC Portuguese Grande Complication timepiece. This new Grande Complication features a 45 x 16.5 millimeter 18-carat red gold case that is water resistant to 30 meters. The silvered dial is protected by a shaped sapphire crystal with a cambered edge. The dial is adorned with applied red gold Arabic markers and an engraved center section created to represent and lines of latitude and longitude on a globe. In addition to time display the dial has four sub dials at the 3-6-9-12 o'clock positions that display a Perpetual Calendar, Minute repeater, Moonphase and Chronograph. The watch is fitted with a hand-sewn brown alligator leather strap and an 8-carat red gold folding clasp that is engraved with "Probus Scafusia" , the motto of the IWC Schaffhausen manufacture that means good, solid craftsmanship as well as 'the honest one'.

IWC Portuguese Grande Complication Watch is powered by a self-winding 79091 caliber that is made up of 657 individual parts and oscillates at a rapid 28,800 vibrations. This magnificent movement offers a chronograph, a minute repeater, a perpetual calendar, and moon phase. The perpetual calendar will not require any manual correction until the year 2100, assuming it were to run continuously. The minute repeater chimes on the hours with single bass notes, on the quarter hours with a bass-treble combination, and on minutes with a single treble note. The 79091 movement has a power reserve of up to 44 hours. IWC will produce just 50 pieces of the Portuguese Grande Complication watch each year.
