The IWC Story

IWC Schaffhausen was founded in 1868 by American engineer Florentine Ariosto Jones, who came to Switzerland with a bold idea: to combine American manufacturing methods with Swiss watchmaking craftsmanship. He established his workshop in Schaffhausen on the Rhine - unusual for a Swiss watch manufacture, which are normally concentrated in the Jura arc - partly because the Rhine Falls provided waterpower and partly because the location offered access to American industrial machinery. The combination of engineering rigour and watchmaking tradition that Jones sought has defined IWC ever since.

The Pilot's Watch lineage, which traces back to the Spezialuhr für Flieger of 1936, is arguably IWC's most important contribution to watch culture. The Big Pilot ref 52 T.S.C. of 1940, with its 55mm case and iconic oversized crown, established the visual language that informs the Big Pilot Watch to this day. IWC's pilot watches are defined by their anti-magnetic protection, legibility, soft-iron inner cages to deflect magnetic fields, and the power reserve displays that have become a signature IWC feature. The current Big Pilot 43 and Big Pilot 46 continue this tradition in cases sized for modern tastes.

The Portugieser, introduced in 1939 for Portuguese navigation officers who wanted a pocket-watch movement in a wristwatch case, became IWC's definitive dress watch family. The Portugieser Chronograph and the Perpetual Calendar Portugieser are considered among the most elegant expressions of Swiss watchmaking at IWC's price tier. Part of Richemont Group since 2000, IWC has expanded its in-house movement capabilities significantly, developing calibres like the IWC-manufactured 52000 series that appear across the Pilot's and Portugieser lines.

Iconic Collections

Since 1940
Big Pilot ↗
The German military pilot watch. Built 1940 for Luftwaffe navigators as a 55mm B-Uhr Beobachtungsuhr with conical onion crown. Modern relaunch in 2002 at 46mm with 7-day Pellaton automatic Cal. 52110, then refined to 43mm in 2021.
Full Big Pilot Guide
Since 1948
Mark XX ↗
The Mark series traces from the 1948 RAF Mark 11 (spec. 6B/346) through Mark XII, XV, XVII, XVIII to the current Mark XX (2022). Cal. 32111 with 120-hour reserve, anti-magnetic soft-iron inner case to 80,000 A/m, the cleanest pilot dial in production.
Full Mark XX Guide
Since 1939
Portugieser ↗
IWC's dress watch benchmark. Originally commissioned by Portuguese agents who wanted the accuracy of a pocket watch movement in a wristwatch, the Portugieser's clean dials, large cases, and IWC-manufactured movements now define the brand's formal register. The Perpetual Calendar is a collector favourite.
Full Portugieser Guide
Since 1967
Aquatimer ↗
IWC's diving collection, notable for its unique external rotating bezel system operated by a crown at 9 o'clock. The Aquatimer Deep Three offers depth measurement to 2,000m using a genuine pressure sensor - one of the most technically advanced dive watches in production.
Full Aquatimer Guide
Since 1967
Ingenieur ↗
Originally an anti-magnetic sports watch for engineers, the Ingenieur was revived with Gérald Genta-designed cases in 1976 and again in 2023 with cleaner, more contemporary proportions. The Ingenieur remains IWC's sports-professional watch - robust, anti-magnetic, and technically purposeful.

Since 1978
Da Vinci
IWC's complication showcase, the Da Vinci collection has historically housed the brand's most complex movements including perpetual calendars and tourbillons. The current Da Vinci range offers an elegant, rounded case architecture that positions it as IWC's most fashion-forward expression.
Since 1985
Portofino ↗
IWC's thin, understated dress watch family, named after the Italian Riviera village. Portofino models prioritise elegance over complication - slim cases, simple dials, and restrained proportions make them ideal everyday dress watches. The Automatic 40 is one of IWC's most approachable entry points.

Heritage Timeline

1868
Florentine Ariosto Jones founds the International Watch Company in Schaffhausen, combining American industrial methods with Swiss watchmaking expertise near the power of the Rhine Falls.
1936
IWC introduces the Spezialuhr für Flieger - the first Pilot's Watch. Its anti-magnetic properties and legibility under flight conditions establish IWC's technical direction for the next century.
1939
The Portugieser launches, built around a high-grade pocket watch movement. The clean, large-dialed watch becomes IWC's most elegant collection and one of the most recognisable Swiss dress watches.
1940
The Big Pilot ref 52 T.S.C. - 55mm, with oversized onion crown and soft-iron anti-magnetic cage - is issued to German and Swiss air forces and establishes the Big Pilot's iconic silhouette.
1976
Gérald Genta redesigns the Ingenieur with a distinctive integrated bracelet and cushion case, creating the SL - a highly collectible sports watch now recognised as one of Genta's finest designs.
2000
IWC joins the Richemont Group, gaining resources for in-house movement development. The following decade sees significant investment in proprietary calibres across all collections.

IWC Questions

Is IWC German or Swiss?
IWC is Swiss, not German. The factory has been in Schaffhausen, Switzerland since the company was founded there in 1868 by American watchmaker Florentine Ariosto Jones. The confusion is cultural: Schaffhausen is in the German-speaking northern part of Switzerland, on the right bank of the Rhine, and the brand uses a Germanic engineering tone in its marketing. Every modern IWC is stamped Swiss Made.
Where are IWC watches made?
In Schaffhausen, Switzerland, at the same factory founded in 1868. IWC operates an extensively vertically integrated manufacture at the Schaffhausen site, producing cases, dials, and in-house movements (the 52000, 69000, 32000, and 82000 caliber families) under one roof. The site has been continuously operational at the same address on the Rhine for more than 155 years.
Who owns IWC?
IWC Schaffhausen has been part of the Swiss luxury group Richemont since 2000, alongside Jaeger-LeCoultre, Vacheron Constantin, A. Lange & Söhne, Cartier, Panerai, Montblanc and others. Before Richemont, IWC was owned by VDO Adolf Schindling AG (1978-2000), and before that family-owned for most of the 20th century.
What is IWC best known for?
Pilot's watches and engineering-led tool watches. Specifically: the Mark XI (1948 RAF navigator's watch and template for every pilot watch since), the Big Pilot 5002 (modern revival of the WWII B-Uhr), the Portugieser (large dress chronograph with railway-track dial), the Ingenieur (1955 anti-magnetic sports watch, redesigned by Gérald Genta in 1976), and the Portofino (slim, Bauhaus-leaning dress watch).
When was IWC founded?
IWC was founded in 1868 by Florentine Ariosto Jones, an American watchmaker from Boston who relocated to Switzerland to combine Swiss craftsmanship with the industrial machine-tool methods then being pioneered in America. He chose Schaffhausen specifically for its abundant hydroelectric power from the Rhine, which drove the factory's machinery.
