Since its founding in 1868, IWC Schaffhausen has been world-renowned for being a leader in Haute Horlogerie, producing timepieces with innovative technology and exclusive design. It began a time when most Americans went West searching for gold, however Boston born watchmaker, Florentine Aristo Jones, went East searching for his treasure. The 27-year-old went all the way to Schaffhausen, Switzerland in order to produce high quality watches for the American market. After a few changes, Ernst Jakob Homberger took over the company in 1905. Under Homberger, two watch families were created which remain icons to this very day – The Pilot’s Watch and the Portuguese. Later, Kurt Klaus who began his career at IWC in 1957, developed IWC’s famous mechanical perpetual calendar.
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 1950s & ’60s watches, will very likely lead one to the same conclusion. In essence, this is because during the 1950s and ’60s, IWC determined they would manufacture some of the very best watches ever made, and put 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 – equalled occasionally perhaps, but never beaten.
An IWC is often referred to as a ‘watchmaker’s watch’. This is because watchmakers simply love them, both to work on and to own.
The watch we see here is special as the movement, one of the Cal.852 series of movements, is considered one of the very best automatic movements of all time. More than this, the dial, case and movement are in outstanding condition.
The incredible, original, unrestored and untouched gold ‘sunburst’ dial is in tip-top condition. Clean, simple, understated and elegant – all the things we are accustomed to with this great brand. We think this combination of onyx inlaid ‘baton’ hour indices, with the gold and black ‘index’ hands and dash minute markers around the dial is hard to beat and the dial contrasts wonderfully with the 18ct yellow gold case. This dial is completed with the wonderful addition of a date window at ‘3’.
This dial is signed with the applied gold ‘IWC’ branding with the ‘International Watch Co’ signature below 12, ‘Automatic’ just above ‘6’ and ‘Swiss’ just below ‘6’.
Usually, we restore the dials of the watches we sell, however, we decided in this case, due to its exceptional condition, to retain its originality and charm for the many collectors who prefer this. It also helps to contrast with almost all of the other watch dials you see on our website which have been restored.
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 see here 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.
The watch contains the original Cal.8521 automatic movement which as mentioned above, was part of the Cal.852 series which was hugely successful for IWC and one of the best automatic movements ever produced.
The 44 hour power reserve movement has been given a full overhaul and service by our vintage specialist watchmaker and is keeping time to within -15 seconds per day. This is outstanding for an automatic of this age and has been checked and confirmed o our electronic Timegrapher. We are very happy to offer a 12 months warranty on this watch movement and will be very pleased to assist you with servicing in future.
It is absolutely immaculate and signed ‘International Watch Co Swiss’ twice, once on the movement and once on the rotor. The movement is also marked with the Cal.8521 and ‘21 Jewels’.
*Please note – our 12 months’ warranty is only applicable if the list price is paid.
This 18ct solid gold case measures 35mm in diameter, excluding the correct IWC signed crown. This wonderful IWC Tonneau case is very heavy and robust and measures 35mm top to bottom and 46mm across the diagonal, including the wonderful lugs.
The case has been cleaned, carefully inspected and very lightly hand-polished, as this was all that was required to bring it back to its current tip-top condition, with no scratches dings or marks of any kind visible to the naked eye. The case, as we would expect from IWC, is very solid and well made and the press-fit case-back closes with a very solid and satisfying ‘pop’, indicating the case has been impeccably built and maintained.
Inside the case-back is signed ‘International Watch Co Swiss’ with the model number 1872 and the serial number 2155141.
As ever, our standard advice applies: Vintage watches should be kept clean and dry at all times.

Even though vintage gold IWC watch prices continue to climb, we still feel sure that top class examples such as this are underpriced.

We then offer these at the fairest prices we can, taking into account our pre and post-sales care and service. This approach means we will never be the cheapest, but nor will we be the most expensive. Indeed there are some well-known stores in West London which are highly successful charging between two to three times the price you see here. We, therefore, consider our prices to be fair, given the quality of watches we have to offer.
