Watch In Focus - IWC Portuguese

Crown and Pushers

The signed crown and mushroom pushers control the automatic IWC Cal. 79350 ETA 7750-based movement inside. The distinctive shape of the pushers singles out the Portuguese from other chronographs at a single glance

Dial

The classic, big white dial is reminiscent of the original Portuguese, commissioned to be oversized and very clear in order to be easily read in difficult conditions when out at sea

Hands and Numerals

The hands and numerals on this model are made of blued steel that can appear as different hues in changing light. The colour can go from a bright royal blue under direct light to almost deep black in the shade

Strap

The blue alligator strap blends beautifully with the blued steel and is soft and supple. The IWC signed buckle uses brushed steel and compliments the brushed sides of the case

Sub-dials

The large, slightly recessed sub-dials display the chronograph minutes at twelve o'clock and running seconds at six o'clock, and break up the expansive dial

Key Facts

  • The Portuguese was created at the request of two Portuguese businessmen that needed a large, clear watch that could be used in all conditions at sea
  • A Calibre 74 hunter pocket watch movement was used in the original Portuguese because it was the most accurate mechanical movement available and the closest to Marine Chronometer standards
  • The bluing of the hands and numerals is done by carefully heating the steel parts to 310 degrees Celsius and quickly dropping them in oil to cool, giving them a coating that partially protects them from corrosion

IWC Portuguese

Posted 31st Oct 2011

The Portuguese have always been known for their expert knowledge of the ocean and sea fairing ability. In the late 1930’s two Portuguese businessmen who frequently sailed around the world requested that a special kind of watch be made for them by IWC. Wrist watches of the time were small and not particularly accurate, so what the two men asked for was a marine chronometer-grade clock that they could wear on their wrists.

Using the Calibre 74, a hunter pocket watch movement that satisfied the men’s accuracy requirements, IWC built a watch called in 1939 called the Portuguese. The 42mm case required to fit the movement was large by the period standards, and had a clear, bold dial with large applied numbers and a large sub dial at six o’clock for the seconds. The cream face was chosen to contrast with the numbers, giving the watch immediate clarity regardless of the conditions.

It wasn’t until 1967 that the next big change occurred in the Portuguese line up. Because of the popularity of the line, many owners did not want to use them for sailing, and so IWC released a more sport orientated version to reinvigorate the original ethos of the model. Called the ‘Yacht Club,’ it looked more like a Rolex Datejust than it did a Portuguese, but nonetheless it became very popular, in fact one of the most popular IWC’s ever.

It was followed soon after by the 70’s Yacht Club II, a watch that again had more in common with another watch than it did with the Portuguese – this time with IWC’s own Ingenieur. The octagonal case and integrated bracelet could not have been any further removed from the original Portuguese, but this did not stop its popularity from soaring. Many Yacht Club II’s were sold in both automatic and quartz guises, riding the wave of a new era of luxury watches.

The Portuguese has not in itself changed much over the course of its life, and the original charm and clarity that made it popular in the first place is still very much present. Complications such as chronographs, perpetual calendars and even tourbillons have been added to what is considered IWC’s flagship range, but the case shape and the bold, applied numerals remain. The hand wound IW5454 is the most faithful to the original with its seconds sub-dial at six o’clock, but the range has most definitely been improved with the addition of the chronograph and the seven day movement, whose twin sub-dials neatly balance out the dial.

To top the current range off, IWC have released a new version of the Yacht Club, reviving the sportiness of the original once again. This time around, the Yacht Club is much more faithful to the Portuguese than was previously, with more focus on sporty design and rugged usability.

The Portuguese is a very elegant watch sat amongst swathes of larger, chunkier watches – if you like your watches to be clean, clear and simple, you can do a lot worse than with a Portuguese.

probus scafusia?

written by A.Morgan - 27th Apr 2011

I’d never really noticed it, unassuming and discreet – but it is there. In letters barely a few millimetres high, it protrudes from the crown; ‘Probus Scafusia.’ We see it, but what does it mean? It would be easy to assume... more
