The Portuguese Yacht Club Chronograph has all the precision of a nautical instrument in its genes. Powered by the rugged IWC-manufactured 89360-calibre movement and water-resistant to 6 bar, the chronograph demonstrates its sporting qualities with a flyback function and an additional flange with quarter-second calibration for recording short periods of time. Longer stop times (hours/minutes) can be read off like a second time on a separate analogue subdial.

The name of the Portuguese Yacht Club Chronograph harks back to the legendary Yacht Club Automatic of the 1960s and 1970s, an ocean-going watch so excellent and exclusive that it became one of IWC’s most successful watches ever. The Portuguese Yacht Club Chronograph has all the precision of a nautical instrument in its genes and boasts a wealth of advanced technical features. Powered by the rugged IWC-manufactured 89361-calibre movement and water-resistant to 6 bar, the chronograph makes no secret of its sporting credentials with a flyback function, an additional flange with quarter-second scale for recording short periods of time and an analogue display for longer stop times on a subdial. The Portuguese Yacht Club Chronograph features crown protection along with luminescent hands and indices. It is available in steel with a black or silver-plated dial and in 18-carat red gold with a slate-coloured dial and black counters. It is supplied with a rubber strap, making it the perfect companion for water sports of all kinds.
Designed and manufactured completely by IWC in Schaffhausen, the 89360-calibre chronograph movement and its successor, the 89361, feature a significantly improved self-winding system and set new watchmaking standards. The design, which occupied an IWC development team for a full 4 years, was necessitated by a revolutionary chronograph display that enables the user to read off even relatively long periods of stopped times – 8 hours and 52 minutes, for example – at a glance: a circular totalizer combines the hour and minute hands as if they were a watch-within-a-watch. In 2012, it was joined by the newly developed 89365 chronograph movement including a stopwatch function with minutes and seconds as well as a flyback function. After further development, the IWC-manufactured movement was known as the 89800 calibre and used for the big digital date and month displays in References 3761 and 3791. The new Ingenieur Perpetual Calendar Digital Date-Month comes equipped with a further development on the theme, the 89802 calibre.
