IWC Schaffhausen says its history began in 1868 with Florentine Ariosto Jones, an American watchmaker who founded the International Watch Co. in Schaffhausen to combine American manufacturing precision with Swiss craftsmanship. On its company pages, IWC also says its location on the banks of the Rhine has helped shape the company since its foundation. The site states that “Probus Scafusia” was first formulated in 1903.
On its official site, IWC documents the Portugieser Eternal Calendar as its first secular perpetual calendar. The brand also states that this watch won the “Aiguille d’Or” at the Grand Prix d’Horlogerie de Genève in 2024. IWC further highlights materials including Ceratanium®, Ceralume®, titanium, ceramics, and coloured ceramics. In its Pilot’s Watches material, the site describes the Pilot’s Venturer Vertical Drive as the first tool watch engineered from the ground up for human spaceflight.
Collections documented on the site include Pilot’s Watches, Portugieser, Portofino, Ingenieur, and Aquatimer. IWC states that Pilot’s Watches were originally conceived in the 1930s to help pilots with navigation. The site describes the Portofino as a dress watch created in the 1980s and inspired by a Lépine pocket watch. The Portugieser family includes the Eternal Calendar.
IWC Schaffhausen remains based in Schaffhausen, Switzerland. Its site shows headquarters and museum facilities there, and it describes watch production in Schaffhausen. IWC also states that every watch is individually assembled by one of its professional watchmakers. A company press release on the site states that the Manufakturzentrum in Schaffhausen was inaugurated on 27 August 2018.
