Unveiled at SIHH 2016, the new Big Pilot’s Watch Spitfire (Ref. IW500917) in 18-carat red gold comes in a 46-millimetre diameter case. The hands, characteristic cone-shaped crown and back of the watch are also made of this warm, glowing precious metal.
The slate-coloured dial with sun-pattern finish creates the fascinating play of light that comes into its own when the watch is gently rotated. The reworking of the dial with the triangle below the chapter ring and the bolder numerals is clearly visible in this watch, too. The brown calfskin strap by Santoni with its orange lining goes perfectly with the watch.
Equipped with a spring-mounted rotor and Pellaton pawl-winding system, the IWC-manufactured 51111 calibre delivers a power reserve of over 7 days, and the complicated gearing of the power reserve stops the movement mechanically after exactly 168 hours.
Stopping the movement before the tension in the spring is exhausted eliminates the danger of diminishing torque in the mainspring, thus ensuring the same level of accuracy all the time the watch is running.
The power reserve display at “3 o’clock” reliably informs the wearer of the time remaining until the movement comes to a stop. The Big Pilot’s Watch Spitfire has a date display at “6 o’clock” and a central seconds.
The red gold case encloses a soft-iron inner cage that protects the movement against magnetic fields. Engraved in the back of the watch is the silhouette of a British fighter plane, the Spitfire, which has given its name to this Pilot’s Watch line.
