Digital Date Display

IWC produced the first “digital” watches in its history as early as 1884. These timepieces, known as Pallweber watches, displayed the hours and minutes using numerals, while the seconds were shown in analogue form with a hand. The state-of-the-art Perpetual Calendar Digital Date-Month calendar movement, which is now likewise found in the new Aquatimer family, shows not only the date but also the month in large numerals. The energy required to advance the month display discs is built up continuously throughout the month by a quick-action switch. A spring-loaded lever on the quick-action switch is lifted a tiny bit further each day by a cam. At the end of the month, the tension in the spring has reached its maximum, and it is time for all that energy to be released; the quick-action switch jumps instantaneously to its starting position and advances both of the month display discs individually, or together, by one position, depending on the month. On 31 December, the leap year disc is also advanced at the same time.

ELEGANT AND A TECHNICAL MASTER STROKE — LIKE A SPITFIRE

The Spitfire was a single engine fighter aircraft commissioned by the Royal Air Force. In the 1930s and 1940s, it was a piece of aerodynamic wizardry with outstanding performance. Since 2003 at IWC, the name Spitfire has also been synonymous with a Pilot’s Watch line that, in terms of elegance and technical expertise, is in a class of its own. This year, the Pilot’s Watch Perpetual Calendar Digital Date-Month Spitfire remains almost unchanged with its slate-coloured dial and stainless-steel case. The large number of displays and complications underscores the watch’s outstanding horological qualities. The digital date and month indicators are displayed in large numerals. This is made possible by a complicated, powerful mechanism which, at the end of the month, synchronously advances up to four displays and, at the end of the year, the leap year display disc as well. This watch, as well as the Big Pilot’s Watch Spitfire in red gold, is supplied with the new brown calfskin strap from Santoni. The rugged leather goes perfectly with a Pilot’s Watch. The Pilot’s Watch Chronograph Spitfire was designed as a sports watch for everyday use. The bezel of the stainless-steel case is polished to a mirror finish, as are two rows of links in the stainless-steel bracelet, giving the watch a special quality feel. This is underscored by the slate-coloured dial with its metallic finish, which matches the grey fuselage of its namesake, the Spitfire. A soft-iron inner case protects the precision movement against magnetic fields and the glass is secured against sudden drops in pressure.

The digital display showing the date and month in large numerals has a long tradition at IWC. Needless to say, the calendar mechanism, programmed until 1 March 2100, even takes the leap day recurring every four years on the 29th of February in its stride. Likewise the analogue display of stop times, which can be read off like the time of day on a totalizer at “12 o’clock”.
