SPICETROVE WATCHES ICONIC HOROLOGIST KURT KLAUS CHARTS THE HISTORY OF THE MOST INNOVATIVE timekeeper’sCHRONOGRAPHS MANUFACTURED BY IWC OVER THE PAST TWOtales DECADES Everything ingenious is simple. That is the guiding principle I have followed all through my time as master watch- maker and head of the research & development department at IWC Schaffhausen. It works every time. Let me take you back to the early Eighties, when I was looking for a mechanical solution for an absolutely reliable perpetual calendar that would also be easy to operate. I had already been involved in the design of many calendars for /www.indiatodayimages.com /www.indiatodayimages.com complicated pocket watches for the Schaffhausen manufactory; but this calendar was supposed to be different. After many years of experimenting, I finally invented a mechanism that competently controlled the different lengths of the months as well as the leap years that are part of the Gregorian calendar. We named it after the Italian inventor, artist and genius Da Vinci. The highly sophisticated mechanism of the new perpetual calendar was mechanically programmed and required no adjust- ment other than the replacement of the century slide supplied with the watch. Only the years 2100, 2200 and 2300 needed a minor correction to be made because these are not leap years according to the Gregorian calendar. The mechanical ver- satility of the new invention was just as impressive as the simplicity of its operation. It automatically set the date, the day of the week, the month, the year, the decade and the century; plus, it showed the current moon phase. ILLUSTRATION BY:ILLUSTRATION SINGH SAURABH SPICETROVE WATCHES Nevertheless, it was an everyday watch cum chronograph that per- mitted aggregate time recording up to 12 hours. It was this movement, with its perpetual calendar and moon phase display, that was eventual- ly to ensure this complicated timepiece of a significant breakthrough in a time not particularly predisposed to mechanical watches. This was a watch that was even able to put modern chip technology in the shadows. Its calendar exhibits had an unbelievable reduction ratio of 6315840000 to 1 on the longest gear train between the escape wheel and the one move- ment of the century slide with the first two digits of the year, every 100 years. Never before had anything of this kind been seen in a wristwatch. This was 1985 and the patented calendar had just found a place in the countless com- plicated wristwatches from IWC. Spring 1990 marked the start of another new age in the recording of time. IWC unveiled a wristwatch that was one of the most complicated ever seen, and yet at the same time the easiest to use: the Grande THE BEAUTY OF THE PILOT’S WATCH UTC (1998) IS THAT WORLD Complication.

These watches have two were inaudible outside the solid platinum case so the glass was freely chronograph hands, one of which can be stopped separately to record two or more separate readings within a given minute. The split-seconds mechanism from IWC could only have been made by specialists ob- sessed with complications for complication’s sake. Indeed, some of the mechanical features have been so radically altered by the company that the patent office recognised them as genuine improvements. And IWC announced the split-seconds chronograph with a stainless steel case in the same tradition as its Pilot’s Watches. In 1993, on the 125th anniversary of the company, the legendary Grande Complication was surpassed. The monument of time measure- ment was called Il Destriero Scafusia and was the most complicated se- ries-produced wristwatch in the world at the time. The first “flying” minute tourbillon in a titanium cage, a split-seconds chronograph and an opulent, hand-decorated movement clearly visible under a sapphire glass back were the additional features of this splendid work of watchmaking. It was pure art. The tourbillon has long been considered the ultimate achievement in mechanical watchmaking. Constructing the mechanism represented an enormous challenge. The filigree construction consisted of about 90 parts, all of which weighed a mere 0.296 grams. Produced in a limited edition of 125 numbered units, the collection quickly sold out. A comparatively small but useful and trendsetting innovation THE PILOTS WATCH DOUBLE CHRONOGRAPH (LEFT); emerged when I developed the first UTC Pilot’s Watch in 1998.

The Deep One was the first and only In 2003, IWC introduced a new highlight: the Portuguese Perpetual diver’s watch with a mechanical depth gauge, a flyback hand for the Calendar. This watch combined the proprietary caliber 5011 with a maximum depth and an inner bezel for the dive time. It was a cleverly perpetual calendar, which operated according to the same principle as devised professional combination instrument and became quite a rarity. the Da Vinci.

However, this is not the only spe- cial feature of this display. By using a larger moon disc, which has more teeth than seen in other watches, the designers have achieved a sig- nificant improvement in accuracy. The deviation of the moon display in the Portuguese Perpetual Calendar is just one day in 577 years. No mechanical wristwatch can do better at this point in time. IWC has invested a considerable amount of time to produce a new mechanical chronograph movement. The result of all this effort, research and testing over the years was the movement, which was abbreviated to Cal. 89360. This is the “motor” which drives the Da Vinci Chronograph and set new standards in the field of horological engineering in 2007. It translated the chronograph logically for the first time into a “watch within a watch”.
