The new Portugieser watches from IWC Schaffhausen

In 2015, IWC Schaffhausen celebrates the 75th birthday of a watch family steeped in tradition:  the Portugieser. In keeping with its jubilee, the new Portugieser collection comes with a host of technol­ogical­ and­ design­ modifications­ as ­well­ as­ new ­features.­ Furthermore,­ the­Swiss ­luxury­watch manufacturer is developing more of its own in-house movements and plans to launch three new calibre families in the years ahead. Initiating this move is the 52000-calibre family, which is found in four models in the new Portugieser collection. The newly designed annual calendar celebrates its debut and the perpetual calendar with its digital large date display is likewise welcomed  into the Portugieser portfolio.

“With the 75th jubilee of the Portugieser in 2015, IWC is celebrating the birthday of a genuine icon,” says Georges Kern, CEO of IWC Schaffhausen. “The Portugieser is not only one of our oldest and best-known watches but probably also the most prestigious of our brand.” In the 1930s, its simple, classic design was way ahead of its time. In terms of precision, its pocket watch movement set a new benchmark while establishing a trend towards larger wristwatches that has made the IWC family popular worldwide and assured it of instant recognition. “With a wealth of sophisticated complications and movements, the Portugieser  line has for many years come to symbolize our expertise as manufacturers of movements,” explains Georges Kern. “None of our other watch families incorporates so many of the technical tours de force of haute horlogerie.”

But the centrepiece of 2015, the IWC Year of the Portugieser,  is the newly designed in-house 52000 calibre, which has already been selected for four models in the latest Portugieser collection. The Schaffhausen-based watch manufacturer is also set to focus more on producing in-house movements in the years ahead.

With the 69000 and 42000 calibres, IWC will establish two new calibre families to be developed and produced in its own workshops. Georges Kern explains the reasons for the company’s decision to expand the range of movements IWC produces itself: “These newly developed calibres are not only excellent additions  to our existing product portfolio; they also set new technical and aesthetic standards. They will help us to develop as a brand, and to continue positioning IWC as a company which is internationally successful in the area of haute horlogerie.”


The new Portugieser Annual Calendar (Ref. 5035) is IWC’s first annual calendar. The month, date and day are shown in three separate, semicircular windows at “12 o’clock”. The date switching mechanism is able to take the differing lengths of the individual months into account but not those for the differing numbers of days in February owing to leap years. The newly developed 52850 calibre has twin barrels to supply the additional torque required to advance the three display discs. Thanks to the new Portugieser Perpetual  Calendar Digital Date-Month Edition “75th Anniversary”  (Ref. 3972), the Portugieser watch family now includes a model featuring a large digital display for the date and month. This exclusive timepiece brings together all IWC’s expertise in its in-house 89801 calibre, which has a perpetual calendar featuring a leap year indicator and quickaction switch for the large displays as well as a chronograph with flyback function. The Portugieser Hand-Wound Eight Days Edition “75th Anniversary” (Ref. 5102) is right at the heart of the watch family. Its purist design is starkly reminis cent  of the original Portugieser (Ref. 325) from the 1930s. But its IWC-manufactured 59215 calibre with an 8-day power reserve is at the leading edge of the industry.

The most important design change in the new Portugieser  Yacht Club Chronograph (Ref. 3905) is immediately obvious: the case diameter has been reduced from 45.4 millimetres to 43.5 millimetres. IWC has heeded requests from many potential buyers who expressed a wish for a slightly smaller version of the sportiest model in the Portugieser watch line. The width of the new rubber strap has also been modified to fit the watch’s character: slim and sporty. Thanks to its elegant design, moderate case height and eminent suitability for everyday use, the Portugieser Chronograph (Ref. 3714) seems destined to retain its status as the most popular of all the Portugieser watches in this anniversary year. For the new collection, IWC has further improved the technological and design features of the Portugieser Perpetual  Calendar with a double moon (Ref. 5034) and the Portugieser Perpetual Calendar with a single moon (Ref. 5033). From 2015, both models will be equipped with IWC-manufactured movements from the new IWC 52000- calibre family, featuring solid red gold rotors and blued screws. The watches will also have arched-edge front glasses and luxurious Santoni straps. For the first time ever, the dial of the double-moon model comes with the railwaytrack-style chapter ring typical of the Portugieser, while the moon phase display sparkles attractively with a panoply  of tiny gold and silver stars.

Starting this year, too, the Portugieser  Automatic (Ref. 5007) will be powered by  an in-house movement from the new 52000-calibre family. The legendary Pellaton winding system has been further improved: the pawls, automatic wheel and rotor bearing are now made of extremely hard, wear-resistant ceramic; and two barrels, rather than just one, build up an impressive 7-day power reserve with a frequency of 4 hertz. For 2015, IWC is making further modifications to the appearance of the  Portugieser Tourbillon Mystère Rétrograde  (Ref. 5046). The new arched-edge front glass makes  the watch appear slimmer. With its exclusive Santoni alligator leather strap and the newly designed in-house  51900 calibre, a timepiece swathed in mystery radiates an even greater attraction. 

Featuring one of the most sophisticated of watchm aking  complications, the Portugieser Minute Repeater (Ref. 5449) continues to fascinate lovers of precision watch mechanics.  For five years now, the Portugieser  Grande Complication (Ref. 3776) has been a union of some of haute horlogerie’s greatest milestones, including the perpetual calendar, perpetual moon phase display and minute repeater. The dial is now clearer and more composed, while the engraving on the back of the case takes the form of a compass rose. Both the red gold and platinum versions  will be available in a limited edition of 250 watches  each. The Portugieser Tourbillon HandWound  (Ref. 5463) with its filigree “whirlwind” will remain a source of delight to connoisseurs  of precision watchmaking.  

“In 2015, with two new and six improved Portugieser references, IWC Schaffhausen will further demonstrate its innova tive prowess and its enormous passion for the art of watchmaking. The line will undergo an overall upgrade with the new in-house 52000-calibre family, which is also visually  more appealing,” says Georges Kern, summarizing the relaunch of the Portugieser watches. “I am convinced that the Portugieser, thanks to its outstanding in-house technology, iconic design and impressive history, will continue to make a decisive contribution to the international renown enjoyed by IWC.”


The focus on manufacturing its own movements and pride in its own watchmaking capabilities are nothing new in Schaffhausen. In an IWC catalogue published as early as 1895, we read: “The production of original watch movements closely follows the rules of watchmaking and the laws of mathematics, systematically applied by the very best master watchmakers. With the exception of the  dials, hands and springs, the vast majority of the parts are manufactured  in our workshops.” Stefan Ihnen, Associate Director  Research & Development at IWC Schaffhausen, looks back on the company’s long watchmaking tradition: “The quest for independence and the internal manufacture of many of the components and mechanisms used in its

watches has been deeply rooted at IWC since the company’s earliest years under F. A. Jones. Like our predecessors, we don’t necessarily manufacture everything down to the last screw but focus specifically on watch movements and complications. For many years now, we’ve been producing  some of haute horlogerie’s most outstanding achievements,  such as perpetual calendars, tourbillons, minute repeaters and moon phase displays in-house.”

The in-house movements in the new 52000-, 69000- and 42000-calibre families also feature numerous technical improvements which, among other things, make them more accurate.  The integration of more ceramic components has made the automatic winding system practically wear-free. Stefan Ihnen: “The material is difficult to process, so using it to make watch parts is unusual and underscores IWC’s pioneering role as a materials innovator in the industry.”

The 52000-calibre family represents the introduction of a new aesthetic to the movements in the Portugieser line. “We’ve enhanced the design and finish of the plates and bridges considerably,” says Christian Knoop, Creative Director  at IWC Schaffhausen. “The slimmer proportions of the rotor provide a more open view of the technology and movements inside the case. You can also clearly see the improved Pellaton winding system with the practically wear-free components made of black and white ceramic.” In the calibres of the 52000 family used for the Portugieser  premium models, the engraved rotor is made of solid 18-carat red gold and is complemented by blued screws, which is an indispensable characteristic of an exquisite in-house movement for many watch connoisseurs. The decoration with circular graining and Geneva stripes, the interplay of red jewels, blue screws and black ceramic elements with the red gold of the rotor: together they convey an overall impression of quality that is in keeping with an in-house movement of this kind.

Despite the elaborate ornamentation, the movements still look highly technical. IWC Schaffhausen thus remains  true to the engineering ethos for which company founder  F. A. Jones laid the cornerstone with production methods that were at the cutting edge of the industry in his time. The decoration of watch movements has a long history in Schaffhausen. Even the first F. A. Jones calibres featured engraving and decorative elements. The reason for this lies in the then common practice among American watchmakers  of presenting movements openly in their shop window displays. This gave end-customers a chance to familiarize themselves with the complex internal mechanism, even if they never actually saw the movement in the finished watches.

Five models in the latest Portugieser collection feature  an arched-edge sapphire glass. It makes the case look slimmer  and underscores the watch’s classic elegance. The strap horn, which closely follows the contours of the case, combined with the slightly curved lugs ensure that the watch fits more comfortably even on a slimmer wrist. The luxurious alligator leather straps made by Italian shoe manu facturer Santoni are among the best that traditional craftsmanship has to offer. One of the secrets of Santoni’s success is the nuanced shading of the leather. Elaborately  finished by hand, every strap comes with an exclusive patina-like shimmer with its own individual colour tones. To achieve this effect, the surface of the leather is polished with a variety of different pastes until it has the desired shading and a perfect sheen.


In 1939, when the first “big wristwatch” left the factory, neither its eye-catching size nor its purist dial and simple, round case conformed to contemporary ideals. Popular taste demanded dainty, wherever possible rectangular, watches in the art deco style. The large case with its grooved bezel – the term used to describe the channelled recess in the ring that holds the glass in place – together with the straight strap horns ran counter to the spirit of the time and its penchant for curlicues and conspicuous  accessories. By contrast, the predecessor to today’s Portugieser  timekeeper had alternating Arabic numerals  with simple hour markers that harmonized perfectly with the narrow, leaf-shaped feuille hands. A facet separated the centre of the dial while the chapter ring featured the “chemin-de-fer” (“railway”) style popular in pocket  watches at the time. These graphic elements appeared once more in the small seconds subdial at “6 o’clock”.
“Today we know that the style of the Portugieser’s dial  and case back then was a major triumph for IWC’s watch makers – a design that is only now garnering the recognition it deserves,” is how Creative Director Christian Knoop describes the origins of the Portugieser. “With its clear-cut structure, no-frills reduction and elegance, it is still styledefining and difficult to surpass. That’s why we took our inspiration for the Portugieser Hand-Wound Eight Days Edition “75th Anniversary” (Ref. 5102) from it. Compared with the original Portugieser, we’ve hardly changed a thing.”


If time is defined as a sequence of events, the 75-year history of the Portugieser watch family is especially rich in unusual occurrences in the art of watchmaking. It all starts with the story surrounding its origins, and how, in the  late 1930s, two Portuguese businessmen ordered wristwatches  with the precision of marine chronometers from the International Watch Co. At the time, the only way of providing the requested accuracy was with a voluminous pocket watch calibre. This was the reason why the watchmakers decided to take the 74-calibre hunter pocket watch movement and later the 98 calibre – both of which fortunately have the crown on the right-hand side – and to house them in wristwatch cases. The first of the new pocket-watch-style wristwatches (Ref. 325) left the factory in 1939. The watch, which was unassumingly listed as a “large wristwatch”, shared the fate of other iconic IWC models. It was way ahead of its time. By the early 1980s, only a few hundred  of them had been produced. It was not until 1993 that, now known as the Portugieser, it was to celebrate its triumphant comeback.

In 1967, at the watch fair in Basel, IWC presented the IWC Yacht Club Automatic (Ref. 811 A/AD), the predecessor of today’s Portugieser Yacht Club Chronograph. This magnificent men’s watch was made for the rigours of the open sea. Its movement, featuring the efficient Pellaton winding system, is spring-suspended in the case, bearing-mounted on rubber buffers and thus had dual shock-resistance.  Exclusiveness combined with ruggedness and suitability for everyday use ensured that the Yacht Club became one of IWC’s bestselling watches.

To mark IWC Schaffhausen’s 125th anniversary in 1993, the Portugieser watch line was reborn. Under the name “Portugieser”, the company produced a limited special edition  that referenced the legendary story of the striking “men’s pocket watch” from the 1930s. The anniversary edition  (Ref. 5441) adopted not only its uncluttered dial design but also the tradition of the voluminous pocket watch movement. Its size, originally unappreciated, now established a new order of magnitude for wristwatches that was to revolutionize the industry and is highly popular all over the world to this day.

In the following years, the Portugieser line continued  to feature new and striking complications and scaled  the peaks of haute horlogerie. In 1995, for example, the extremely complex Minute Repeater (Ref. 5240) and the Chronograph with Split-Seconds Hand (Ref. 3712) were unveiled.

In the year 2000, the IWC-manufactured 7-day 5000 calibre  in the Portugieser Automatic 2000 (Ref. 5000), which had been 5 years in the making, marked a technological quantum leap in the history of automatic movements. Among other things, it incorporated bidirectional Pellaton winding and a balance with a Breguet spring for maximum precision.  The limited edition sold out in no time and was the foundation for the lasting success of the Portugieser family.

In 2003, the Portugieser Perpetual Calendar (Ref. 5021) with the newly developed calendar mechanism was further proof of IWC innovation at its best. The timepiece combined  a perpetual calendar with a perpetual moon phase display and a 7-day power reserve generated by the Pellaton  pawl-winding system. The display showing the moon in the northern and southern hemispheres diverges by just 1 day in 577.5 years from the actual phase of the moon.

In 2005, the limited Portugieser F. A. Jones (Ref. 5442) with manual winding was launched as a classic memorial to the company’s founder. Its IWC-manufactured 98290 calibre  takes some of its design cues from the first F. A. Jones movements, such as the elongated index and the threequarter bridge decorated with Geneva stripes. A further  example of watchmaking extravagance joined the Portugieser complications in 2007: the regulateur with separate hour, minute and seconds displays (Ref. 5444). In 2008, a Portugieser Hand-Wound (Ref. 5445) featured in the IWC Vintage Collection. With its railway-track-style chapter ring and arched-edge front glass, the watch bore an uncanny resemblance to the 1939 original but, from a technical point of view, represented the state of the art.

In 2010, IWC celebrated another “Portugieser” year with a host of fascinating new products. Leading the way was the flagship of the collection, the Portugieser Grande Complication  (Ref. 3774). The Portugieser Tourbillon Mystère  Rétrograde (Ref. 5044) combined the magic of a floating tourbillon with the logic of a date hand that reverts  to its starting position. With its numerous stylistic references, the Portugieser Hand-Wound (Ref. 5454) bridges the gap between the original Portugieser and the present. The Portugieser Yacht Club Chronograph (Ref. 3902) takes up the tradition of the 1967 Yacht Club Automatic and brings a sporty note to the Portugieser family.  

In 2011, the Portugieser line was enriched by the addition of the Portugieser Sidérale Scafusia (Ref. 5041). It is the most exclusive and complicated mechanical watch ever made by IWC. It took the project team at IWC Schaffhausen  10 years to develop and build this spectacular masterpiece. Complications such as the patented constant-force tourbillon, sidereal time and the times of sunrise and sunset  are testimony to the inventiveness of IWC’s watch makers.  The individually calculated star chart and the wealth of possible configurations make each timepiece unmistakable  and unique in its own right. In 2013, the Portugieser HandWound Eight Days (Ref. 5102) with an 8-day power  reserve and the Portugieser Chronograph Classic (Ref. 3904) with an in-house chronograph brought the exciting  and eventf ul history of the Portugieser family to a temporary halt.




To mark the occasion of the 75th anniversary of the Portugieser watch family, IWC has decided to pay fitting tribute to a little known yet wonderfully attractive version of the original Portugieser with the new Portugieser Hand-Wound Eight Days Edition “75th Anniversary”. The design of this limited anniversary edition is almost identical to that of its predecessor, while the act of manually winding the movement once a week is a pleasing ritual.

Those familiar with the history of IWC are most likely to associate the original Portugieser (Ref. 325) from the 1930s with its legendary black and white dial. This classic, minim alist design was one of the main reasons that the Portugieser  from IWC Schaffhausen went on to become a true icon in the world of watchmaking. However, a number of different dial versions were also launched in the same year the watch family was founded. The new Portugieser Hand-Wound Eight Days Edition “75th Anniversary” (Ref. IW510205 and IW510206) is a homage to a version of the original Portugieser that until now has been fairly unknown. Fortunately, an original version of this model had remained in a private collection, and was a source of inspiration for IWC’s designers. This historic piece features all the­attributes­which­have­defined­the­appearance­of­thePortugieser to this day: Arabic numerals, slim feuille hands, railway-track-style chapter ring and small seconds at  “6 o’clock”. However, the inner chapter ring, hour indices and Arabic numerals are aesthetically very prominent in gold brown with black edging. The new Reference IW510206 in 18-carat red gold with silver-plated dial has inherited the colour scheme and company logo of its forebear almost without change. Light green dial elements on the stainlesssteel version (Ref. IW510205) contrast well against the matte black dial. A new feature is the date display on the subdial at “6 o’clock”: in the 21st century, that level of convenience is de rigueur in a watch.


Out­of­respect­for­the­watch’s­iconic­design,­and­in­orderto retain the characteristic symmetry and simplicity of the dial, the 8-day power reserve display was positioned on the side of the watch facing the movement. Just how long the watch will continue running until it needs to once more be wound by hand can be seen through the transparent sapphire-glass back. For many watch connoisseurs, this is not even necessary, because they look forward to the weekly ritual of winding the watch. IWC’s in-house 59215- calibre movement, which measures a stately 37.8 millimetres  in diameter, reliably supplies the watch with energy for 8 days. Actually, it would be almost 9 days, were it not for an intelligent system that blocks the movement after the­first­192­hours,­or­precisely­8­days.­Stopping­the­movement before all the tension in the spring has been exhausted eliminates the danger of diminishing torque in the mainspring. This ensures the same level of accuracy the whole time the watch is running. The Glucydur®* beryllium alloy indexless balance oscillates at a frequency of 4 hertz, or 28,800 beats per hour. Like the Breguet spring bent into shape using traditional watchmaking techniques, this also helps to make the watch extremely precise. The coved bezel, a typical design characteristic of the Portugieser line, and the arched-edge sapphire glass help to make the case appear less bulky despite its 12-millimetre height and 43-millimetre diameter.

The Portugieser Hand-Wound Eight Days Edition “75th Anniversary” will be available in a limited edition of 175 watches  in 18-carat red gold with a silver-plated dial (Ref. IW510206); the stainless-steel version with a black dial (Ref. IW510205) is­limited­to­750­watches.­All­models­are­fitted­with­exclusive alligator leather straps produced by Italian shoe manufacturer Santoni.


With a clear focus on technology and development, the Swiss watch manufacturer IWC Schaffhausen has been producing timepieces of lasting value since 1868. The company has gained an international reputation based on a passion­for­innovative­solutions­and­technical­ingenuity.­Oneof the world’s leading brands in the luxury watch segment, IWC­crafts­masterpieces­of­haute­horlogerie­at­their­finest,combining supreme precision with exclusive design.
