IWC Schaffhausen is extending its Portofino collection with the addition of new chronographs. The Portofino Chronograph 39 combines a classic Portofino design with a touch of sportiness in a compact case size of 39 millimetres.

Since 1984, the Portofino has been one of IWC Schaffhausen’s most successful collections. Its timeless, elegant and original design, with a minimalist round case, Roman numerals and simple hour markers appealed to both men and women at the time.

For many years, chronographs have formed an integral part of the collection, lending it a subtle, sporty touch. To complement the existing 42-millimetre Portofino Chronogaph, IWC Schaffhausen now introduces the Portofino Chronograph 39 (Ref. IW3914) in a compact and very wearable case size of 39 millimetres.

About IWC Schaffhausen

In 1868, the American watchmaker and entrepreneur Florentine Ariosto Jones travelled from Boston to Switzerland and founded the ‘International Watch Company’ in Schaffhausen. His visionary dream was to combine advanced American manufacturing methods with the craftsmanship of Swiss watchmakers to make the best pocket watches of his time. In doing so, he not only laid the foundation for IWC’s unique engineering approach but also established the centralised production of mechanical watches in Switzerland.

Over its 150 year history, IWC Schaffhausen has developed a reputation for creating functional complications, especially chronographs and calendars, which are ingenious, robust, and easy for customers to use. A pioneer in the use of titanium and ceramics, IWC today specialises in highly engineered technical watch cases manufactured from advanced materials, such as titanium aluminide and Ceratanium®. Preferring the principle of “form follows function” over decoration, the Swiss watch manufacturer’s timeless creations embody their owners’ dreams and ambitions as they journey through life.

IWC sources materials responsibly and takes action to minimise its impact on the environment, creating intrinsically sustainable timepieces that are built to last for generations. The company prides itself in training its own future watchmakers and engineers, as well as offering an excellent working environment for all employees. IWC also partners with organisations that work globally to support children and young people.

*IWC Schaffhausen only uses alligator leather which is fully compliant with the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES). All our leather products and straps sold in California comply with the legal provisions stipulated by the State of California.
