Portuguese Yacht Club Chronograph. 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 Portuguese Yacht Club Chronograph has all the precision of a nautical instrument in its genes and boasts a wealth of advanced tech-nical 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 fly- back function, an additional flange with quarter-second calibration for recording short periods of time and an analogue display for longer stop times on a subdial. The Portuguese Yacht Club Chronograph is the only Portuguese model to feature crown protection along with luminescent hands and indices. It is available in stainless steel with a black or silver-plated dial and in rose gold with a slate-coloured dial and black totalizers. It is supplied with a rubber strap, making it the perfect companion for water sports of all kinds. Developed and manufactured completely by IWC in Schaffhausen, the 89360-calibre chronograph movement features a significantly improved self-winding system and sets 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 times - 8 hours and 52 minutes, for example - at a glance: a circular totaliser combines the hour and minute counters as if they were a watch within a watch. Apart from this, the winding system now has four instead of two pawls to transmit the energy developed by the rotor, increasing the mechanism's efficiency by a noticeable 30 percent. After further development, the movement was known as the 89800 calibre and used for the large digital date and month displays in the Da Vinci Perpetual Calendar Digital Date-Month. Portuguese On Precision Course To Success: 'Heroes of the sea, noble people ...' is the opening line of the Portuguese national anthem. It is the expression of a collective memory through which Portugal's great seafarers - Vasco da Gama, Bartolomeu Dias or Ferdinand Magellan - remain alive to this day. Above all, it was their outstanding sailing skills, their precise nautical charts and the use of instruments such as the astrolabe and Jacob's staff to determine their latitude on the high seas that enabled them to embark on their daredevil voyages of discovery to West Africa and across the world's oceans. The pioneers of Portuguese seafaring managed to reconcile seemingly incompatible opposites: their hot-blooded temperament with cool calculation; outstanding courage with respect for natural forces; and historical tradition with all that was new in science and technology. The Portuguese watches from IWC are a distant echo from that glorious past. They combine the tradition of nautical instruments with contemporary design and forward-looking mechanics.
