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 did! 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 beautifully simple, clean and elegant. It is also completely original, unrestored and untouched and remains in tip-top condition. It carries an incredible 14ct yellow gold, 33mm case and the Calibre 8521 series movement within is considered to be one of the very best automatic movements of its time.

The Dial

The fully original silver-white dial is classic IWC style from this period. Clean, simple, understated and elegant – all the things we are accustomed to with this great brand. In our opinion, the combination of the yellow gilt ‘dauphine’ hands, ‘pencil’ hour indices with double pencil hour indices at 12 and 6 and dot minute markers around the dial is hard to beat and the dial contrasts wonderfully with the 14ct yellow gold case. The dial also has the wonderful addition of a perfectly proportioned date window at ‘3’.

This dial is signed with the infinitely more attractive International Watch Company Schaffhausen signature and ‘Automatic’ just above 6 with ‘Swiss’ at the very bottom, just below 6.

As the dial is original and unrestored, this has been left untouched by our restoration team due to its superb condition. Usually, we restore the dials of the watches we sell, however we decided in this case to leave it alone. It also helps to contrast with almost all of the other watch dials you see on our website, which have been restored. The hands, likewise, have also been left in their original condition.

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.

The Watch Movement

The watch contains the original Cal.8521 automatic movement which was part of the Cal.852 series. This movement was hugely successful for IWC and one of the best automatic movements ever produced.

The movement has been given a full overhaul and service and after calibration and final testing is keeping time to within +15 seconds per day, confirmed by our electronic Timegrapher. This is outstanding for an automatic of this age! We are therefore very happy to offer a 12 months warranty on this watch movement and will be very pleased to assist you with servicing in future. The movement also has a power reserve of 42 hours when fully wound.

The movement is in excellent condition and is signed ‘International Watch Co Swiss’ twice, once on the movement and once on the rotor. The movement is also marked Cal.8521 and 21 Jewels with the serial number 1,301,106 which dates this watch to 1953.

*Please note – our 12 months’ warranty is only applicable if the list price is paid.

The Case

The very high quality 14ct yellow gold watch case measures 33mm in diameter, excluding the correctly signed crown. The case is of a three-piece design and of very sturdy construction with the strong press-fit case-back fitting back with a very solid and reassuring click.

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 this watch left the factory, which is totally amazing.

Inside the case-back all the markings are correct and as expected signed ‘International Watch Co Swiss’ with the case serial number 1337326 and Swiss Geneva 14ct hallmarks.

The Strap and Buckle

The watch is fitted with a new high quality brown genuine alligator strap and a plain gold-plated buckle. However, if a different colour or style of strap is preferred, please let us know and we will do our best to oblige free of charge. We carry tan, conker, dark brown and black in stock in plain padded leather, crocodile skin or lizard skin. We can also obtain most types and colours from our watch strap partners at WatchObsession within 48hrs. Please take a look at their huge range of straps if you wish.

The Box and Papers

Although there are no original papers with this watch, the movement, case numbers and hallmarks all match, dating the watch to 1953.

Detailed particulars will be included with our purchase receipt for your interest and security. A separate insurance valuation for the replacement value of this watch will also be provided at the time of sale along with our unique ‘Lifetime Authenticity Guarantee’ which states: “If this watch proves to be anything less than 100% genuine, authentic and original, a full refund will be given at any time”.

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.
