The Ingenieur Chronograph Sport is limited to 500 watches and is powered by the IWC-manufactured 89361-calibre movement. The 44-millimetre titanium case, black dial and black calfskin strap combine to create a sporty and elegant look. The small seconds hand at “6 o’clock”, shaped like a bolt of lightning, serves as a reminder that a soft-iron inner case protects the movement from the negative influence of magnetic fields. The upper totalizer makes it possible to read off stopped hours and minutes as simply as the time on a subdial. Stopped times up to 1 minute are measured by the central chronograph seconds hand. Used in combination with the tachymeter scale, it also shows the average speed achieved over a measured distance of 1,000 metres.
