**Big Ingenieur** (Ref. 5005, "Grosse Ingenieur" in German) is a larger version of the [[IWC Ingenieur|Ingenieur]] wristwatch produced by [[IWC]] between [[2007]] and [[2011]].

===== Overview =====
In contrast to the standard model of the [[IWC Ingenieur|Ingenieur]], which has a soft-iron inner case, the large version (with 45.4 mm case diameter) features the large IWC caliber 51113 with [[Pellaton winding system|automatic Pellaton winding system]] and [[7 days|seven days power reserve]]. This high-quality [[manufacture movement]] can be admired through a [[sapphire crystal]] caseback. In addition to the date display, there is also a [[power reserve indicator]].

The stainless steel version launched first in [[2007]], with the gold and platinum models following in [[2008]]. The steel version features a black dial and either a black alligator strap or steel bracelet, Ref. IW500501 and IW500505, respectively. The heavy platinum and gold references (IW500502 and IW500503) have a silver dial and black or brown alligator strap. All standard Big Ingenieur models feature the Arabic numeral 12 alone on the dial, with other hours marked with lumed bars.

A special edition, IW500508, was issued in [[2011]] as a tribute to football player, Zinédine Zidane. In addition to a brown dial, it features the sole Arabic numeral 10 in red and "10" in the rotor medallion. 500 examples were produced.
