Replica IWC watches

International Watch Co, also known as IWC, is a high-end Swiss watch manufacturer located in Schaffhausen, Switzerland. IWC is an active member of the Federation of the Swiss Watch Industry FH.

Located in Schaffhausen, IWC Schaffhausen is notable for being the only major Swiss watch factory located in eastern Switzerland, as the majority of the well-known Swiss watch manufacturers are located in western Switzerland.Notwithstanding, the lingua franca of IWC is German.

IWC's motto is Probus Scafusia (L.), meaning "good, solid craftsmanship from Schaffhausen" and was established in 1903 as the "Official Motto".

Technician Johann Vogel from Wangen an der Aare in Solothurn played an important role as technical director. He designed and developed IWC calibers until 1919.

In 1885, IWC manufactured the first digital watch based on a patent granted to an Austrian by the name of Pallweber. It was a simple design, but was unable to replace the traditional analogue display.

Some modern movements in watches of IWC are based on movements supplied by ETA and heavily modified by IWC. This is common practice by many high end watch marques. In particular, the Caliber 30110 is a modified ETA 2892A2, and the Caliber 79230/79320/79350 is a modified ETA/Valjoux 7750. Like all high end automatic watches, IWC watches lose or gain approximately 4 seconds a day.

Movements not based on ETA movements include the Caliber 5000 and the Caliber 8000, which use the Pellaton winding system, and the pocket watch movements used in the Portuguese F.A. Jones and other IWC pocket watches. IWC also used a JLC meca-quartz movement in their older Portofino chronographs.
