It is said that owning a vintage IWC is something everyone with a serious interest in vintage watches should aspire to. A strong statement perhaps, but a little time spent researching IWC and their ’50s & ’60s watches, will very likely lead one to the same conclusion. In essence, this is because during the 1950s and 1960s, IWC determined they would manufacture some of the very best watches ever made and quite simply, this is what they achieved! The craftsmanship, technical excellence and sheer beauty of their exquisite movements and cases, manufactured during the ‘golden age’ of watch-making, has never been beaten – perhaps equalled occasionally, but never beaten!
An IWC is often referred to as a ‘watchmaker’s watch’. This is simply because watchmakers love them, both to work on and to own. This is due to the design, technical excellence and in particular, the sheer beauty of their watch movements.
The watch here is highly impressive, not only for its wonderfully fully original, elegant dial, but also for being both oversized at 36mm in diameter and for having an 18ct pink gold case. The fully original, unrestored and untouched dial is in truly amazing condition and shows some unique signs of ageing. However, what lies beneath is a truly iconic movement, the Calibre 89, which is considered to be one of the very best hand-wound movements of all time!
The style of the dial is typically vintage IWC of this period. Clean, simple, elegant and totally understated. All the things we are accustomed to with IWC. This is the classic and simple IWC dial which the company became known by, and which has become almost a trademark in itself.
This beautifully understated, original, unrestored and untouched silver dial carries pink gold ‘pencil’ hour indices and the original, unrestored pink gold ‘lance’ hands. As mentioned above, the dial has a wonderful, unique patina with some fine spotting. The dial carries the infinitely more attractive, early ‘International Watch Company Schaffhausen’ signature and is signed ‘Swiss’ at the very bottom.
The dial has a great deal of appeal due to its classic signs of ageing and very even patina, including some beautiful golden brown fading and even spotting across the dial. Due to its relatively good condition and for reasons of retaining the character and the originality of the watch, we have left it completely alone. If however, you would prefer the dial sympathetically restoring, we will be happy to arrange this for you without any extra charge.
Please note, studio lights, professional-grade digital cameras, and macro lenses can be very unkind to an unrestored vintage watch dial. Also the dial here measures less than 1.25 inches across, so the image you’re seeing may be between 5 – 25 times larger than the watch itself. Therefore please keep in mind you are seeing many tiny flaws which cannot be seen, or will be very hard to see with the naked eye, even under close examination. Suffice to say, on the wrist, in natural light, this dial looks much better and carries a great deal more charm than the photographs portray.
Many consider the IWC Cal.89 to be one of the great hand-wound movements of the 20th century. This movement was originally developed in 1946 by the genius of watchmaking, Albert Pellaton, who designed this movement to meet the most demanding and highly rigorous specifications of the British Ministry of Defence. Each movement went through a 44-day testing period in five positions and a a range of temperature from -5° to +46° C. It was produced for military use, continuously for over 30 years and became ‘The standard’ for all military-grade timepieces. The movement also became an IWC mainstay for the commercial market, remaining in production until the mid-1990s.
We have already touched on the craftsmanship and sheer beauty of IWC movements. Some examples of the extra care and attention are the finishing applied to the bridges or plates, characterised by a series of arc-grained bars etched lightly onto bridges or plates, creating a wave-like effect. This is known as a ‘Geneva Wave’ finish. Furthermore, all the edges of the plates are beautifully bevelled which is very difficult and time-consuming to achieve. Lastly, each of the ruby jewels is set in brass ‘chantons’ which are then screwed into the plates rather than setting the jewel directly into the plates. This is the kind of detail which sets IWC apart.
The movement has been fully overhauled by a Master Watchmaker. This means stripping the watch down to all its component parts, careful inspection under high magnification, replacement where necessary with only genuine IWC parts, then careful reassembly and adjustment before final calibration in 5 positions. The watch winds, sets and runs accurately and reliably within +6 seconds per day, averaged over 5 positions which is outstanding for any watch of this age. We are therefore highly confident in offering a 1-year warranty with this watch movement.
The movement is correctly signed ‘International Watch Co’ and ‘Swiss’ and carries the Calibre number 89 and the movement serial number 1632039, dating this watch to 1961.
*Please note – our 12 months warranty is only included if the list price is paid.
The very high quality, oversized 18ct pink gold watch case measures an impressive 36mm in diameter, excluding the correct unsigned crown. The case is of a sturdy three-piece design and the press-fit case-back fits back with a very solid and reassuring click. Importantly, it is of full thickness and has never been engraved.
The condition of the watch case is truly immaculate, with no scratches, dings or other damage visible to the naked eye and has therefore simply required a professional clean and gentle hand-polish, to bring back the almost new look of the watch. As can be seen, all the edges are as crisp as the day the watch left the factory, which is totally amazing.
Inside the case-back we find the case is all correctly signed ‘International Watch Co.’, ‘Swiss’ with the IWC brand, the Swiss Geneva 18ct hallmarks and the case serial number 1736409 along with the reference number 604.
As ever, our standard advice applies: Vintage watches should be kept clean and dry at all times.
