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.
This particular IWC is special for a number reasons. Firstly its ‘Flying Lugs’ and ‘Disco Volante’ style watch case are very rare. More of this later under ‘Case’.
The legendary Cal.8521 ‘Date’ is one of the earlier IWC automatic movements which also makes this watch more collectable. This movement is from the 852 series which was a huge success for IWC, selling in record numbers during the early 1950s. This was part of the broader IWC Cal.85 movement family introduced in 1950 and remaining in production until 1996. All designed completely in-house by IWC, these are incredibly reliable and accurate timepieces.
This is a beautifully elegant and understated dial, in ivory cream with gold ‘baton’ hour indices and the original restored gold ‘Index’ hands. This is the classic 1950s IWC non- numeral dial. During the 1950s and ’60s, IWC’s clean and simple dial design became almost a trademark in itself for the company.
It is signed with the infinitely more attractive early International Watch Company Schaffhausen signature and with ‘Automatic’ below and ‘Swiss’ at the very bottom of the dial.
It is quite rare for an IWC from the 1950s to carry a date function and this elevates the value of this watch.
This is the original dial which has been sympathetically restored to the very highest standards by the best vintage watch dial restorers in the UK.
The term ‘Disco Volante’, Italian for flying saucer, originates around 1952 to describe a series of low, flat experimental open-top sports racing cars produced by Alfa Romeo. Also, of course, it referred to comic and science fiction spacecraft. Then later, a series of watches released in the late 1950s by Audemars Piguet in the ref. 5093 and Patek Philippe in the ref. 2552, and Vacheron & Constantin, in the ref. 6006. The term then became more generally used for watches which follow the style, appearing flatter in profile and more streamlined and futuristic, through the use of a wider bezel and a sunken crown. It was also, of course, the name used for Largo’s fantastically advanced motor yacht, in one of the best James Bond films ever made – Thunderball!
It is rare to find an IWC with anything but a traditional style watch case, but occasionally it produced something a little special such as the watch we see here. The case has more than a hint of the Disco Volante look as it carries a wider bezel which due to its profile, gives the impression of having two bezels with the crown sunken into the outer bezel. This is very attractive, but the addition of the separate flying lugs arrangement is inspired! These sweep quickly and deeply back in order to present the watch beautifully on the wrist, without overpowering the overall case design.
At 35mm in diameter, excluding the IWC signed crown, the oversized watch case is exceptionally large for an IWC automatic of this period. The case measures 40mm overall, including the lugs, so the watch appears larger on the wrist.
The watch case is in immaculate condition with no marks at all visible to the naked eye. In fact, with no marks even to show the case has been opened! The case-back is of full thickness and has never been inscribed. Inside the case-back all is correct and as expected: Signed IWC Schaffhausen, with the early IWC brand and Swiss Geneva 18ct hallmarks. The case also carries the external case number 1390458.
Please note, as ever our standard advice applies: Vintage watches should be kept clean and dry at all times.
This is the original Cal.8521 automatic movement which was part of the Cal.852 series which was hugely successful for IWC and one of the best automatic movements ever produced. It is absolutely immaculate and signed ‘International Watch Co’ and ‘Swiss’ twice, once on the movement and once on the rotor. The movement is also marked Cal. 8521 and 21 Jewels with themserial number 1413268 which dates this watch to 1957/58. The 44 hour power reserve movement has been given a full overhaul and service and it is keeping time to within +2 seconds per day, confirmed by our electronic Timegrapher. This is outstanding for an automatic of this age! 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.
*Please note – our 12 months’ warranty is only applicable if the list price is paid
