====== IWC 89760 ======
**Cal. 89760** is a high-end [[manufacture]] [[flyback]] [[automatic chronograph]] with [[GMT hand]] produced by [[IWC]] since [[2016]].

===== Details =====
IWC had long used [[IWC 7900|a family of automatic chronograph movements]] based on the [[Valjoux 7750]]. These were not only used in basic [[chronograph]] watches but [[complicated]] pieces, including [[grande complication]] and [[tourbillon]] watches. Two important complications on that base were the [[perpetual calendar]] and [[rattrapante]] modules that helped re-establish IWC as a maker of advanced watch movements. IWC had never had a [[flyback]] chronograph, however, and many buyers looked down at the pedestrian base on which these complications were developed. In [[2007]], IWC introduced a new [[IWC Da Vinci Chronograph 3764|Da Vinci Chronograph, Ref. 3764]] with an all-new [[in-house]] movement developed by [[Kurt Klaus]]. The new [[IWC 89360|Cal. 89360]] was an advanced design with a [[flyback]] chronograph, efficient [[Pellaton winding]], and power reserve of 68 hours, even while operating at 28,800 A/h.

In [[2016]], IWC launched a variation on the chronograph movement with a separately adjustable [[GMT]] hand, **Cal. 89630**.
