Portuguese Yacht Club Chronograph (Ref. 3902)
In 2010, the Portuguese watches from IWC are entering their eighth decade. To celebrate its oldest and most popular collection, IWC introduced numerous Portuguese novelties at SIHH 2010, such as the Portuguese Grande Complication, the Portuguese Tourbillon Mystère Rétrograde or the Portuguese Yacht Club Chronograph. These large format, mechanicalprecision instruments perpetuate the legacy of the famous seafarers to this day, and hand it down to today’s explorers.
This week, I will introduce all the ten new IWC Portuguese watches released at SIHH 2010. Today, let’s go over the first two stunning novelties by IWC – the Portuguese Yacht Club Chronograph (Ref. 3902) and the Portuguese Hand-Wound (Ref. IW5454).

Portuguese Yacht Club Chronograph (Ref. 3902)
The Portuguese Yacht Club Chronograph (Ref. 3902) not only revives the name of one of the most successful IWC watches of the last century. The new Yacht Club also introduces a generous pinch of sporting appeal into the Portuguese family – and in this way does justice to its legendary predecessor. It has been upgraded technically to make it the perfect companion for navigation and sailing: in the IWC-manufactured 89360-calibre movement, it has one of the most modern and robust chronograph movements on board – with a flyback function and analogue display of the long stop times via two hands on an inner dial. It is water-resistant to 6 bar and is the only Portuguese to have luminous hands and indices. Its large, clear dial makes it a perfect chronograph. It is available in steel with a black or silver-plated dial and in red gold with a slate-coloured dial and black registers.

The Yacht Club is reporting back for duty in a remarkable way after an absence of around a quarter of a century. It is available as the Portuguese Yacht Club Chronograph in three variants: in steel with a silver-plated dial, rhodium-plated luminescent hands and appliqués. Again in steel with a black dial, silver-plated flange and rhodium-plated hands and appliqués, also luminescent. The most refined model in 18 carat red gold has an slate-coloured dial with a sun pattern ground finish, subtly contrasted by the black small seconds display circle and the black ring for the aggregate minutes of the chronograph. This model is distinguished additionally by gold-plated hands and solid red gold appliqués.
All three variants are worn on a black rubber strap with a folding clasp. And during those hours of total calm on board, far out to sea, a glance through the sapphire-glass back at the IWC-manufactured movement with IWC’s double-pawl winding even brings the yachtsman a little distraction.

Portuguese Hand-Wound (Ref. 5454)
The Portuguese Hand-Wound is a contemporary witness to IWC’s Portuguese family of watches, which has been in existence since 1939. Often when the manufacturer celebrates a significant anniversary, it presents connoisseurs with an item that further extends that particular success story. That is once again the case with this unassuming beauty, which celebrates the family’s eighth decade.

Portuguese Hand-Wound (Ref. 5454)
Back to the roots: with this message the new Portuguese Hand-Wound (Ref. 5454) appeals to all those who are still fascinated by the original form and understatement of the Portuguese. And rightly so: in the IWC-manufactured 98295 calibre hand-wound movement it, too, has the technology of a classic pocket watch on board. Two variants in steel drawing closely on the original interpret the theme anew and with a breath of modernity: in the version with the black dial, this finds expression in a silver seconds scale with discreet red “60″ marking. The model with a silver-plated dial differs from all the previous faces of the Portuguese watch through a grey counter for the small seconds and likewise red “60″ marking.
