With this 4K-video we present you the new IWC Schaffhausen Pilot’s Watch Chronograph Edition “Tribute to 3705” (Ref. 387905), it pays homage to an exceptional timepiece and is limited to 1000 pieces. The timepiece is the “IWC Fliegerchronograph Keramik” from 1994. It was IWC’s first Pilot’s Watch with a case made of black zirconium oxide ceramic. Despite its use of this highly innovative material and its purist instrument design, the chronograph enjoyed little success. After only a small quantity made (more than 1000 … much less than 2000 pieces), production was discontinued a few years later. With its black ceramic case, the Ref. 3705 is also an early testimony to the extensive materials expertise that IWC has acquired since the 1980s.
The dial of the “Tribute to 3705” is a replica of the original from the 1990s. Two totalizers at “9” and “12” o’clock display stop times of up to 12 hours, the small second is located at “6” o’clock. Another feature is the day and date display at “3” o’clock. The ref. 3705 was pioneering in the use of black ceramic, and the tribute edition likewise features a recent innovation from IWC’s material scientists: the case, chronograph pushers and pin buckle are made of Ceratanium®, an IWC-developed material that is light and robust like titanium, but also similarly hard and scratch-resistant like ceramic. In the first step, the case components are machined from a special titanium alloy. Afterwards, the parts are treated in a furnace firing process, during which a phase transformation takes place, and the surface of the material assumes properties similar to ceramic.
While the “IWC Fliegerchronograph Keramik” from 1994, Ref. 3705, was powered by the ETA/Valjoux calibre 7750, the new 41 mm Pilot’s Watch Chronograph Edition “Tribute to 3705” is powered by the IWC in-house calibre 69380. This robust and precise chronograph movement in classic column-wheel design is one of the latest developments from the brands engineers. A bi-directional pawl winding system reliably builds up a power reserve of 46 hours.
The Pilot’s Watch Chronograph Edition “Tribute to 3705” is available exclusively through https://www.iwc.com as a limited-edition of 1000 pieces for 12.800 Euro including 20 % VAT.
