IWC 89360

Cal. 89360 is a high-end flyback automatic chronograph manufacture movement produced by IWC since 2007.

Details

IWC had long used 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 Da Vinci Chronograph, Ref. 3764 with an all-new in-house movement developed by Kurt Klaus. The new 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. Cal. 89360 had 40 jewels.

IWC updated the movement in 2011 with 38 jewels to become Cal. 89361. This replaced Cal. 89360 in some applications. The similar Cal. 89365 was launched in 2012 with 35 jewels. Both remain in production as of 2019.
