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 ’60s, IWC determined they would manufacture some of the very best watches ever made and quite simply, this is what it 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 – perhaps equalled occasionally, but never beaten!
An IWC is often referred to as a ‘watchmaker’s watch’. This is simply because watchmakers love them, both to work on and to own. This is due to the design, technical excellence and particularly the sheer beauty of their watch movements.
The example here sports a truly iconic movement. Designed and built to military specifications, the Cal.89 has certainly stood the test of time, remaining in production for both civilian and military use for over 40 years!
The Dial
The stunning 1940s Art Deco ivory cream dial is very distinctive, furnished by gold ‘pencil’ and stud hour indices, matched with the original, restored, yellow gold ‘Index’ style hands. It has the clean, almost sparse look typical of a gentleman’s IWC dress watch, however the gold minute markers around the dial, frame this unusual design beautifully.
The dial is signed with the infinitely more attractive, early, International Watch Company, Schaffhausen signature.
This is the original dial which has been restored to the very highest standards by our dial restorers who are considered to be the best in the UK.
The Movement
Many consider the IWC Cal.89 to be one of the great manually wound movements of the 20th century. The movement was originally developed in 1946 by the genius in watchmaking, Albert Pellaton, who designed this movement to meet the most demanding and highly rigorous specifications of the British Ministry of Defence. Each movement went through a 44-day testing period in five positions and ranging in temperatures from -5° to +46° C. It was produced for military use continuously for over 30 years and became ‘The standard’ for military-grade timepieces. The movement also became an IWC mainstay for the commercial market, remaining in production until the mid-1990s.
The craftsmanship and sheer beauty of IWC movements is extraordinary. Some examples of the extra care and attention taken can be seen in the finishing applied to the bridges or plates, characterised by a series of arc-grained bars etched lightly onto bridges or plates, creating a wave-like effect. This is known as a ‘Geneva Wave’ finish. Furthermore, all the edges of the plates are beautifully bevelled which is very difficult and time-consuming to achieve. Lastly, each of the ruby jewels is set in brass ‘chantons’ which are then screwed into the plates, rather than setting the jewel directly into the plates. These are just the kind of details which set IWC apart.
The movement has been fully overhauled by a Master Watchmaker. This means stripping the watch down to all its component parts, careful inspection under high magnification, replacement where necessary with only genuine IWC parts, then careful reassembly and adjustment before final calibration in 5 positions. This watch, therefore, winds, sets and runs accurately and reliably, within +8 seconds per day, averaged over 5 positions and also has a 44-hour power reserve when fully wound. Please bear in mind this is outstanding for any watch of this age. We are therefore highly confident in offering 12 months warranty with this watch movement*.
The movement is all correctly signed ‘International Watch Co’ and ‘Swiss’ with both the Calibre number and the serial number 1147978 which date this watch to 1948.
*Please note – our 12 months’ warranty is only applicable if the full list price is paid.
The Case
The very high quality, IWC Swiss made 18ct yellow gold watch case measures 35mm in diameter, excluding the correct IWC crown. The case is of a two-piece design for increased dust and moisture protection. It is in the typically 1940s style with classic lines, attractive sweeping lugs and a flat rounded edge case-back.
The high polished, full thickness case-back has never been inscribed. This watch has been exceptionally well cared for and the main case body, bezel and case-back are all in beautiful condition with no scratches, dings or other damage visible to the naked eye. Therefore after careful inspection, the case has simply required a professional clean and gentle hand-polish, to bring back the almost new look of the watch.
Inside the case-back all the markings are correct and as expected. Here we find the case carries the famous ‘Probus IWC Scafusia’ branding meaning “Good, Solid Craftsmanship from Schaffhausen” which was established in 1903 as the “Official Motto.” In addition, the case-back carries two Swiss Geneva hallmarks and the case reference number 1173536.
As ever, our standard advice applies: Vintage watches should be kept clean and dry at all times.
The Strap and Buckle
The watch is fitted with a new high-quality water-resistant dark brown Alligator strap and 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. We carry tan, conker, dark brown and black in stock in plain padded leather, crocodile skin or lizard skin and can also obtain most types and colours from our partners at ‘Watch Obsession’ within 48hrs.
