IWC Portuguese Tourbillon Hand-Wound Watch

Tweet
Written by Bojan Pavlovic on May 1, 2012 in IWC Portuguese, IWC Watches - 5 Comments

In 2010, the Swiss watchmaker IWC unveiled Portuguese Tourbillon Hand-Wound Watch that pays a tribute to the company founder, F. A. Jones. The extremely large flying minute tourbillon situated at the 9 o’clock position occupies nearly one third of the dial’s surface and immediately attracts curious glances.

This tourbillon watch with the referent number IW544705 is powered by the in-house manufactured caliber 98900 mechanical movement based on an almost century-old pocket watch movement. The mechanism belongs to the long tradition of the 98 caliber which was manufactured from the mid-1930s for the hunter pocket watch and has been continuously improved by IWC for over 80 years. Since it is so perfectly suited for large hand-wound wristwatches, it is no coincidence that it is very common in Portuguese family (Portuguese Minute Repeater and Portuguese Hand-Wound, for example).

IWC Portuguese Tourbillon Hand-Wound WatchThe tourbillon is not the only thing that was added to this movement, but its frequency was also increased by IWC’s engineers from 18,000 vibrations per hour to more appealing 28,800 beats per hour. Thus, the precision of the timepiece was further increased. The hand-wound movement is built on 21 jewels and it is capable of holding no less than 54 hours of power reserve when fully wound. The mechanism represents the finest fusion of the tradition and the latest watchmaking technology. Further, the movement’s intricately decorated nickel-plated three-quarter bridge made of nickel silver can be seen through the transparent sapphire-glass case back.

The Sophisticated Case and an Easy to Read Dial

The watch is housed in a round case crafted from 18-karat red gold with 43.1 mm in diameter and the thickness of 11 mm. The case is protected on both sides by convex sapphire glasses with antireflective coatings and it is constructed to resist water pressure up to 30 meters (100 feet).

A sleek, black dial with applied Arabic numerals lies under the front sapphire glass.  At the 9 o’clock position, there is a flying minute tourbillon that reveals the horological nobility and provides a clear view into the escapement of the movement. The tourbillon consists of 47 individual parts and it weights only 0.689 grams. In this watch, tourbillon does not act as sub-dial seconds indicator as we used to tourbillons, so the subsidiary seconds counter is displayed through a totalizer located at the 6 o’clock position. The empty space at the 3 o’clock position is nicely filled with the signature of the brand’s founding father, “F. A. Jones”.

IWC Portuguese Tourbillon Hand-Wound WatchThe refined dial also features nice feuille, or in other words, leaf-styled hour and minute hands and a railway-track chapter ring for minutes.  There is also the brand’s logo situated below the numeral twelve.

The watch case is smoothly connected with a fashionable black alligator leather strap that offers extreme flexibility and easiness of wrist movement. IWC Portuguese Tourbillon Hand-Wound Watch is produced in the series of only 500 specimens and each timepiece can be purchased for approximately $60,000.

    Everything is absolutely great on this watch except two things, water resistance and the price. A watch which costs $60,000 must have water resistance of at least 200 meters. This one has water resistance of 30 meters. Something isn`t right in this situation, do you agree?

  2. Franklin Tran May 16, 2012

    Ian, this watch isn`t intended to be for diving, It`s intended to be for any urban man who wants an elegant watch for some gallant events.

  3. Ian Tompson May 16, 2012

    Yes, you are right about that, but I think that a watch which costs $60,000 must have better water resistance.

    The model IW544705 looks extraordinary. I just like the combination of black color and red gold. That’s the winning combination, in my opinion. The watch is great. It’s a pity because there is only one model of this nice timepiece.

  5. Federico Mayo August 28, 2012

    I don’t like this watch. Actually, I don’t like any type of watch which has gold on its case or bracelet. My ideal watch is made of a steel case and a light brown leather strap, with a white dial and silver details inside the dial.
