A combination of American style and Swiss technology. Florentine Ariosto Jones, an American from Boston, rented his first factory in Schaffhausen, Switzerland in 1869. Florentine Ariosto Jones had set a goal to combine the American system of mechanism with the detailed work of the Swiss. The IWC factory was the only watch factory in East Switzerland even until this day. Ferdinand Porsche worked for IWC as an external designer for the watches and he was the one who introduced the idea of using titanium to manufacture watches. IWC was the first watch company to use titanium to manufacture a watch. The most well-known series of the IWC brand is the Portuguese Series, which included watches such as the Portuguese Perpetual Calendar, the Portuguese Tourbillon Mystere, the Portuguese Minute Repeater, etc IWC also manufactured the Aquatimer Automatic 2000, which allowed the watch to reach a 2000 meter depth. IWC made its own innovations for the technology of watch making.
