Description
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 1960s, IWC determined it would design and manufacture some of the very best movements ever made, and put simply, this is what it did! The craftsmanship, technical excellence and sheer beauty of its exquisite movements and cases, manufactured during the ‘golden age’ of watch-making, has never been beaten – equalled, perhaps, occasionally, 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, to own and to collect.
The watch we see here is special because it has a very heavy 18ct, 35mm case, and the Cal. 85XX series movement is considered one of the very best automatic movements of all time.
The Movement
The original Cal. 8541, 21 Jewel automatic movement fitted to this watch is considered the ultimate evolution of a series of movements considered to be the best ever automatics produced by IWC and one of horology’s best of all time.** The series originated with the Cal. 85 in 1950 and evolved through Cal. 852-3-4. The last digit, ie 1, denotes this movement has a date function.
Given the series was in production for over 40 years and enhanced with each iteration, this movement has certainly proven itself as a success. It is very robust, reliable and accurate and easy to service. It’s winding system, developed by IWC’s famous technical director, Albert Pellaton, is particularly celebrated and has achieved great acclaim.
The movement has been fully overhauled by a Master Watchmaker. This means dismantling the movement down to each of its component parts, careful inspection under high magnification, replacement where necessary with only genuine IWC replacement parts, then careful reassembly and adjustment, before final calibration in 5 positions. This watch winds, sets and runs accurately and reliably and when tested on our electronic timegrapher machine, it was found to be running within +8 seconds per day, which is outstanding for any watch of this age. We are therefore highly confident in offering a 12-month warranty with this watch movement*.
The movement is all signed correctly: ‘International Watch Co.’ and ‘Swiss’ with both the Calibre number 8541 and the serial number 2125429 which dates this watch to 1971.
*Please note – our 12 months’ warranty is only applicable if the full list price is paid.
**Brunner and Pfeiffer-Belli, in their book “Wristwatches Armbanduhren Montres-bracelets” refers to the Cal. 853 as “one of the best automatic movements ever built in Switzerland”.
The Dial
The classic style of the dial is typical vintage IWC of this period – clean, simple, understated and elegant. All the things we are accustomed to with this prestigious brand.
The silver-white ‘starburst’ dial is furnished with black onyx inlaid ‘baton’ hour indices, matched with the original ‘index’ hands. Normally we restore the dials of each of our watches as part of the overall restoration. However, here the dial is in tip-top condition and far too good to restore so we have left it alone apart from the lens which has been replaced with a new original.
This is the original dial which has been left alone and completely untouched.
The Case
The very high quality, heavyweight, 18ct yellow gold watch case measures 35mm in diameter, excluding the 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. It is 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.
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 2179599.
The Strap and Buckle
The watch is fitted with a new high quality brown alligator strap, which suits the watch perfectly and the strap is fitted is with a plain gold-plated buckle. 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 1971.
Detailed particulars will be included with the receipt, along with our 12 months ‘ warranty*. 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”.

In Conclusion
