American watchmaker Florentine Ariosto Jones founded The International Watch Co ( IWC ) in 1868. This luxury  watch manufacturer is still based in Schaffhausen, Switzerland, were they started trading almost 150 years ago.

In 1885 the company began keeping detailed records for every watch that has left the factory, including details of the caliber, materials used and cases. In the case of later models, these also include the reference number, delivery date and the name of the authorized dealer. For a small fee, the owner can obtain precise information about their watch, as long as the watch is at least ten years old.

The company claims that its service department has the parts and is capable of repairing and maintaining watches from every era since IWC's foundation in 1868.

IWC Schaffhausen produces luxury watches that combine traditional Swiss craftsmanship with modern technology and engineering.
