What collections does IWC Schaffhausen produce?

IWC Schaffhausen manufactures six main families: Portugieser (oversized dress watches with chronograph, perpetual calendar and 7-day power reserve), Pilot's Watches (aviation instruments from Mark XX to Big Pilot), Portofino (Italian-inspired dress watches with moon phase and chronograph), Aquatimer (professional dive watches with SafeDive bezel), Ingenieur (sport watches with antimagnetic protection) and Da Vinci (barrel-shaped complications, limited production). Our collection covers the first six families with 96 references across all sizes and complications.

What is the Pellaton winding system in IWC movements?

The Pellaton automatic winding system, invented by IWC technical director Albert Pellaton in 1950, uses a pawl mechanism instead of a traditional reverser wheel. Two pawl levers alternate engagement with a ratchet wheel, winding the mainspring in both rotor directions with high efficiency. Modern IWC calibers (52000 series) use ceramic Pellaton components for reduced wear and improved longevity. This system enables the 7-day (168-hour) power reserve found in Portuguese and Big Pilot references.

What is the difference between Portuguese and Portofino?

Both are IWC dress watches but differ in dial philosophy and size. The Portugieser features oversized subdials, railway minute track and slim bezels that maximize dial visibility — typically 40mm to 44.2mm. The Portofino uses a cleaner, more minimalist dial layout with applied hour markers and a thicker bezel — ranging from 34mm ladies to 42mm chronograph. Portuguese targets watch enthusiasts who appreciate mechanical complexity on display. Portofino targets those preferring understated Italian elegance for everyday dress wear.

What sizes are available across IWC collections?

IWC offers one of the widest size ranges among Swiss manufacturers. Portofino starts at 34mm (ladies automatic) and 37mm (moon phase). Portuguese ranges from 40mm (Automatic) to 44.2mm (Perpetual Calendar). Mark watches are 40mm across the board. Aquatimer sits at 42-44mm. Pilot chronographs run 41-44.5mm. The Big Pilot commands 46.2mm — the largest IWC production reference. Case thickness varies from 9.2mm on the Portofino Automatic to 16.5mm on the Big Pilot.

What materials does IWC use for cases?

IWC uses stainless steel (316L standard, with 904L on select models), titanium (Aquatimer and Pilot editions), ceramic (Top Gun Pilot chronographs in matte black and green), 18K red gold and 18K white gold (Portuguese and Portofino special editions), bronze (Pilot Spitfire and Big Pilot editions) and platinum (limited Portuguese references). Ceramic cases are scratch-resistant and lightweight. Titanium offers a 40% weight reduction over steel. Bronze develops a natural patina unique to each wearer.
