====== IWC Ingenieur Automatic 3239 ======
  *See Also [[IWC Ingenieur]]

The **Ingenieur Automatic** (Ref. 3239) was [[IWC]]'s main entry in the [[IWC Ingenieur|Ingenieur]] line from [[2013]] until [[2016]].

===== Overview =====
Both [[Rolex]] and IWC saw the need for a [[engineer|watch for engineers and scientists]] in the 1950s, combining rugged [[automatic]] movements, [[water-resistant]] cases, and [[anti-magnetic]] concepts in the [[Rolex Milgauss]] and this IWC Ingenieur. The concept has remained for over 50 years, with the [[IWC Ingenieur|IWC Ingenieur family]] spawning many models, including an iconic redesign by famed designer [[Genta, Gerald|Gerald Genta]], a pivot to [[motor racing]], and the use of exotic materials like [[titanium]] and [[ceramic]].

IWC re-launched the Ingenieur line in [[2005]] with the in-house [[IWC 80111|Cal. 80111]] [[IWC Ingenieur Automatic 3227|Ref. 3227 Ingenieur Automatic]], styled like Genta's original [[IWC Ingenieur SL|Ingenieur SL]] before going "Vintage" with the successor, [[IWC Ingenieur Automatic 3233|Ref. 3233 Ingenieur]]. But neither of these achieved the sales success of other Ingenieur models, so IWC rebooted the line again for [[2013]] focused on their [[IWC Ingenieur Mercedes AMG|partnership with Mercedes-AMG]]. This required a high-tech but affordable basic Ingenieur model.

The base model of the new Ingenieur lineup was this Ref. 3239 Ingenieur Automatic. It reinterpreted the Genta case once again, mixing in design elements of the successful [[IWC Ingenieur Chronograph 3725|Ingenieur Chronograph]] and AMG models of Ref. 3227 from a decade earlier. The result was an attractive update to the Ingenieur SL style, with a sculpted bezel and triangular crown guards being the most obvious features. Looking closer, one notices that all numerals have been excised from the hour and seconds tracks, though the dual-level dial suggests the [[IWC Ingenieur Automatic 3227|Ref. IW322702 AMG Ingenieur]] in other aspects. The bar markers are simplified like the [[IWC Ingenieur Automatic 3233|"Vintage" Ingenieur]] but the rest of the design is more like contemporary offerings like the [[IWC Ingenieur Automatic 3236|Ref. 3236 "Mission Earth"]].

One welcome element of the new reference is the return of a soft iron inner case for magnetic resistance, a feature missing from the "Vintage" model and many other contemporary Ingenieur offerings. But the movement is no longer an in-house design, with "[[IWC 30110|Cal. 30110]]" being based on the widely used [[ETA 2892-A2]]. The result is a less-expensive offering, even with a steel bracelet.

Another major departure from previous offerings was the lack of precious metals or exotic materials for the Ingenieur Automatic. Instead, every reference is crafted of stainless steel with the various reference numbers indicating dial variations.

The Ingenieur Ref. 3239 was phased out in [[2017]], to be replaced by another vintage-looking offering, the [[IWC Ingenieur Automatic 3570|Ref. 3570 Ingenieur Automatic]].

===== 2013-2017 Ingenieur Range =====
The Ingenieur line was entirely refreshed in [[2013]] focusing on the [[IWC Ingenieur Mercedes AMG|Mercedes-AMG partnership]]. The base offering was the [[IWC Ingenieur Automatic 3239|Ref. 3239 Ingenieur Automatic]], with most of the focus on the exotic [[IWC Ingenieur Tourbillon 5900|Ref. 5900 Ingenieur Constant-Force Tourbillon]] and [[IWC Ingenieur Perpetual Calendar 3792|Ref. 3792 Perpetual Calendar Digital Date-Month]].

Other models included the [[IWC Ingenieur Dual Time 3264|Ref. 3264 Dual Time Titanium]], [[IWC Ingenieur Double Chronograph 3865|Ref. 3865 Double Chronograph Titanium]], [[IWC Ingenieur Automatic 3224|Ref. 3224 Carbon Performance Ceramic]], [[IWC Ingenieur Automatic 3225|Ref. 3225 AMG Black Series Ceramic]], and [[IWC Ingenieur Automatic 3246|Ref. 3246 AMG GT]].

The entire range was replaced again in [[2017]] with vintage-looking offerings like the [[IWC Ingenieur Automatic 3570|Ref. 3570 Ingenieur Automatic]].
