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. This watch is previously restored to a very high standard and remains in tip-top condition. It has an incredible 18ct yellow gold, 33mm case, and its Cal.8521 series movement is considered to be one of the very best automatic movements.

The Dial

The silver-white dial is classic IWC from this period. Clean, simple, understated and elegant. All the things we are accustomed to with this great brand. We think this combination of yellow gilt ‘index’ hands, yellow gold ‘pencil’ hour indices, with double pencil hour indices at 12, and dot minute markers around the dial is hard to beat and the dial contrasts wonderfully with the 18ct yellow gold case. This dial also has the wonderful addition of a perfectly proportioned date window at ‘3’.

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

This dial has been previously restored to a very high standard and, as can be seen, remains in outstanding condition.

The Movement

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.

The 44 hour power reserve movement has been given a full overhaul and service and it 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.

It is absolutely incredible 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 the serial number 1350620 which dates this watch to 1954.

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

The Case

The very high quality, heavyweight, 18ct 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. The press-fit case-back is very strong and fits 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 we find the case is all correctly signed ‘International Watch Co. Swiss’ with the IWC brand, Swiss Geneva 18ct hallmarks and the case serial number 1357806.

The Strap and Buckle

The watch is fitted with a new high quality black leather strap and plain gold-plated buckle, which we feel suits the watch perfectly. However, if a different colour or different style strap is preferred, please let us know and we will do our best to provide your choice, free of charge.

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 1954.

A separate insurance valuation for the replacement value of this watch will 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 totally authentic, or not as described, Vintage Gold Watches of London will offer you a full refund at any time”.
