IWC Portuguese Perpetual Calendar Blue Dial 18kt White Gold Black Leather Men's Watch IW503203

An encounter with visionary mindsHamdi Chatti suggested meeting Robert Greubel and Stephen Forsey in order to present the project, with no strings tied. The discussion soon developed into a passionate brainstorming session. A quarter of an hour was enough to convince the two "inventor-watchmakers" based in La Chaux-de-Fonds to plunge into the fantastic adventure. And two days later, Robert Greubel called Chatti to share the ideas they had already developed meanwhile…Harry Winston and Greubel Forsey: a virtuoso association of exceptional talents…Opus 6 thus took shape within record time, just six months between the first contacts and the presentation at Baselworld thanks to the close collaboration with Robert Greubel and Stephen Forsey. The French and English "mechanical architects" have been associates for almost ten years and are endowed with an obvious flair for inventive mechanical engineering, admirably displayed in their ground breaking Double Tourbillon 30°.Born in France in 1960 and extremely gifted in the field of micromechanical engineering, Robert Greubel started repairing watches in his father's workshop. After earning an initial watchmaking degree, he continued his studies, discovered the field of complicated horology and graduated from the Watchmaker's School in Dreux (France). He then joined IWC as a prototype maker and took part in the development of the Grand Complication. Initially hired as a prototype maker at Renaud & Papi, today an affiliate company of Audemars Piguet, he soon moved on to become joint managing director and a partner in the firm. Then, in 1992, he met the brilliant English watchmaker Stephen Forsey. Born in 1967 in St. Albans, the capital of England in Roman times and located some thirty kilometres north of London, where tens of thousands of marine chronometers were produced, Forsey initially worked for Asprey's in restoring antique watches. But it was in Switzerland, with Robert Greubel, that he came to excel in grandes sonneries, minute repeater, tourbillons and perpetual calendars.The watchYet another tourbillon?Yes indeed - but, as one has come to expect from an Opus, this is not just any tourbillon. Truly novel and totally apart, it makes its own distinctive contribution to the quest for precision. This double tourbillon reigns supreme, freed visually as well as from the going trains thanks to three time display counters for the hours, minutes and seconds. In a word, the ultimate tourbillon system. While the company in La Chaux-de-Fonds knuckled down to the task of integrating its movement for the project, the Harry Winston teams devoted their energies to designing an entirely original architecture for this highly technical movement.A 30-degree double tourbillon? Strange…In keeping with the Harry Winston spirit dedicated to "the exceptional and nothing else", the emotion 30° could not be merely just another tourbillon. This mechanism proves that there is still plenty of uncharted territory to be explored at the very peak of Haute Horlogerie with its combination of two important technical feats. The first lies in the very shape of the system inclined at a 30-degree angle, hence its name "Emotion 30°". Why 30 degrees? So as to enable the balance to oscillate constantly in all planes and to achieve a more perfect precision of timing.… but exceptionally pure.The second feat, apart from the hours, minutes and small seconds displayed on three circular counters, lies in the fact that the movement is the sole and inescapable focus of attention. That is simply because the gear trains are invisible, or rather because they have been concealed. Harry Winston and Greubel Forsey have thus succeeded in integrating this fantastic Double Tourbillon 30° mechanism within the Opus spirit, thus creating a masterful watch: the bridge is screwed to the mainplate of the movement with a balance wheel moving freely above the mainplate liberating the double tourbillon of any superstructure and thus providing an unobstructed and stunningly pure view of the mechanism, finally free of the gear trains that generally obscure visual access. The result is a genuine marvel of precision, featuring an impressive theatre that is partly due to its inclined angle, which may be admired in its full three-dimensional splendour.Opus 6: maturity.With its satellite hour display system, Opus V was rightly acclaimed as a watch demonstrating spectacular creativity and technical mastery. While the sober design of Opus 6 is anything but extravagant, it is nonetheless imbued with an unusually complex horological spirit entirely in tune with the two fundamental demands of the Opus concept: uniting two of the greatest talents in contemporary watchmaking, and surprising observers by the virtuosity of its movement.Matching a complicated mechanism with sophisticated architectureThe idea being to place the movement in the centre and to build everything else around it, the challenge lay in marrying the case to the movement. Harry Winston responded by choosing a case similar to its Ocean collection and featuring an interior design that begins with the double tourbillon 30° and structures the case and movement on two levels while integrating the time displays. Thus, while the tourbillon system is mounted on the mainplate of the movement, the small seconds counter appears at 11 o'clock on a second level, while the third level at 2 o'clock displays the hours and minutes on two time circular counters by two co-axial discs.The powerful symbolism of the number "6"…This mechanism is a technical and aesthetic marvel. Many will find themselves lost for words when contemplating the purity and the ingenuity of this "terraced" construction. One need only look at the watch face on to see the figure 6 take shape, appearing by a trick of the eye on the bridge and hour and minutes sector. Why "6"? Firstly, because this is the 6th edition of Opus; secondly, it signals the year of its launch 2006; and finally because it stands for the extremely limited number of these watches that will be produced. This also perfectly suits such an innately exclusive model. And as is if that were not enough, the case designers have added another playful touch. This time, admire the watch from a sideways angle, and you will see the figure "6" transform into an ampersand (you remember, the & sign just above the figure on a classic computer keyboard!) linking the names of the two partners in this project: Harry Winston and Greubel Forsey, engraved around the edge of the dial.Exceptional finishing for an incredible watchSeasoned connoisseurs will recognise the superlative quality of the finishing details of Opus 6, such as the graining of the bridge, or the satin-brushed finish of the counter covers, making a splendid contrast with the midnight blue mainplate background and beautifully matching the white gold bezel. Inspired by the same spirit, the hour, minute and seconds indicators are finished in red. An attentive observer will note that the pillars of the double tourbillon bridge are an architectural accomplishment in themselves, featuring uprights shaped like the signature Harry Winston arches and which are reflected in the crown guard at 3 o'clock.
