18K IWC SPITFIRE PERPETUAL 3791

Hyvin harvinainen ja suurikokoinen 18k IWC Pilot Spitfire Perpetual Digital Date-Month Calendar Chronograph.  Ref. IW379105.

Tämä vuoden 2013 Pilot malliston monimutkaisimman perpetuaali kronografin ominaisuudet on helpoin kertoa IWC:n virallisen kuvauksen kautta:

The Spitfire Perpetual Calendar Digital Date-Month shows the date and month in large numerals together with the 4 years of the leap year cycle. A specially designed quick-action switch generates the energy needed to advance the numeral discs. Every night, when the date display moves forward, it taps a little of the energy, stores it and then discharges it precisely at the end of the month or year. The perpetual calendar will not require intervention by a watchmaker until 2100, a year that breaks with the conventional four-year cycle and will not be a leap year.

The shimmering, slate-coloured metallic dial with its sun-pattern finish and the warm tone of the 18-carat red gold case give the watch its premium-quality allure. The rotor takes the form of an elegant Spitfire silhouette. The Spitfire Chronograph in 18-carat red gold features a sun-pattern finish that reflects incident light in spiralling circles. The dark colour of the dial and the altimeter-like date display ensure that the Spitfire with its IWC-manufactured 89801 calibre bears a closer resemblance to classic instrumentation. The subdial at “12 o’clock” displays the minutes clocked by the stopwatch while the central hand shows elapsed seconds. Thanks to the integrated flyback function, the running stopwatch hand can be reset to zero and immediately starts recording another time.
