With the Big Pilot’s Watch Constant-Force Tourbillon Edition “IWC Racing”, IWC Schaffhausen presents a horological masterpiece in a design inspired by the technical world of motorsport. The timepiece features IWC’s patented constant-force mechanism, which transmits even impulses of force to the escapement, ensuring a highly exact rate. The matte black Ceratanium® case and the fully blacked-out 94800 calibre lend this limited-edition Big Pilot’s Watch a unique and futuristic appearance.
Motor racing combines performance engineering, cutting-edge technology and innovative materials with pure adrenaline. The dynamic world of motorsport and the beauty of advanced racing machines have inspired the Big Pilot’s Watch Constant-Force Tourbillon Edition “IWC Racing” (Ref. IW590501). Limited to 15 pieces, this unique timepiece combines IWC’s complex constant-force tourbillon with a matte black Ceratanium® case and the iconic Big Pilot’s Watch design.
Note: the live images show an “in development” prototype that was photographed 6 months ago and it was not the final product. As you can notice, several important visual features differ.
A constant force ensures even oscillations
The powerful engine is the IWC-manufactured 94800 calibre, one of the most complicated mechanical movements ever designed in Schaffhausen. The patented constant-force mechanism disengages the escapement from the direct flow of power through the wheel train and transmits completely even impulses of energy to the escape wheel.
In conjunction with the tourbillon, which compensates for the negative influences of gravity on the oscillating system, this ensures a highly accurate rate. The plates and bridges are fully blackened having undergone an elaborate rhodium-plating process to match the colour of the case. The movement, which is reminiscent of an engine block, can be viewed through the sapphire glass back.
The first Pilot’s Watch in Ceratanium®
The 46.2-millimetre case, striking conical crown and pin buckle are all made of Ceratanium®. This IWC-developed material is light and robust like titanium but also similarly hard and scratch-resistant like ceramic. During the first step of the manufacturing process, the components are machined with maximum precision from a proprietary titanium alloy.
Afterwards, they are fired at very high temperatures in a kiln. It is during this furnacing process that a phase transformation takes place, and the surface of the material assumes properties similar to those of ceramic. Other characteristics of Ceratanium® are its skin-friendliness and unique matte black finish.
Details inspired by the world of racing
While the constant-force tourbillon at 9 o’clock is the eyecatcher on the dial, the design also features a double moon phase display for the northern and southern hemispheres. White numerals and yellow-coloured accents imitate a dashboard, while the power reserve display at 4 o’clock is reminiscent of a tachometer.
The louvred, ring-shaped structure of the outer dial ring takes inspiration from the cold air intakes of a high-performance engine. Even the black rubber strap incorporates a detail from the world of racing. It features an inlay made of Alcantara®*, a synthetic and durable micro-fibre with superb grip, which is often used for the seats and steering wheel covers of performance cars.
