International Watch Company was founded in 1868 by Florentine Ariosto Jones — an American watchmaker from Boston who traveled to Schaffhausen with a radical idea: combine American industrial manufacturing methods with Swiss artisanal finishing. Jones chose Schaffhausen specifically because it was the only Swiss town with a hydroelectric power plant, which could drive the automated lathes and milling machines he needed for mass production of high-quality movements. That founding principle — industrial precision married to hand-finishing — remains the IWC identity today. The brand does not chase ultra-thin records or astronomical complications; it builds robust, legible, technically honest watches designed to perform reliably for decades.

In the late 1930s, two Portuguese businessmen requested precision deck-observed watches from IWC — marine chronometer-grade timepieces that could be worn on the wrist. IWC responded by housing its hunter-pocket-watch calibers in oversized cases (43–44mm), fitted with thin bezels and ultra-legible Arabic numerals. The result was too large for the era and production was minimal, but the design was rediscovered in the 1990s when oversized watches became fashionable. The modern Portugieser Chronograph (ref. 3716) carries that DNA: a 41mm case, applied Arabic numerals, feuille hands, and a clean two-register layout that has become one of the most copied dial designs in the industry. The in-house caliber 69355 (introduced 2021) replaced the long-running ETA 7750-based 79350, adding a column-wheel mechanism and 46-hour power reserve.
IWC occupies a pragmatic position on the secondary market. The brand carries strong recognition and legitimate horological credibility — the Pellaton winding system, the ceramic components in modern movements, and the 5-year warranty on new watches all signal serious engineering. Yet pre-owned pricing is highly accessible: a Portugieser Chronograph in steel that retails for $8,450 can be acquired pre-owned for $4,500–$6,000. The Pilot Mark XX trades at 30–45% off retail. This is not a reflection of quality — it is a reflection of market dynamics. IWC does not artificially restrict supply the way some competitors do, so the secondary market reflects actual value rather than scarcity premium. For buyers who prioritize substance over speculation, IWC is one of the smartest buys in Swiss watchmaking.
Our Diamond District specialists provide transparent, market-accurate valuations for every IWC reference. We understand the nuances: movement generation (in-house 69355 vs. ETA 7750-based 79350), case material, dial variation (blue vs. silver vs. black), and the presence of the original box and warranty card all factor into the offer.
