Indeed, it is the Tribute to the 3705
**Powered by the in-house 69380 calibre and fitted on a black calfskin
strap, this special edition is limited to 1000 watches and sold exclusively on

The newly released Pilot 's Watch Chronograph Edition "Tribute to 3705"
(Ref. 387905) pays homage to this exceptional timepiece and is limited to
1000 pieces. The dial 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 original ref. 3705 was powered by the Valjoux calibre 7750, the new
Pilot's Watch Chronograph Edition "Tribute to 3705" boasts sophisticated
movement technology from Schaffhausen. Inside the 41-millimetre case, the in-
house 69380 calibre is at work. This robust and precise chronograph movement
in classic column wheel design is one of the latest developments from IWC's
engineers. A bi-directional pawl winding system reliably builds up a power
reserve of 46 hours.
