Cal. 89630 is a high-end manufacture flyback automatic chronograph with perpetual calendar produced by IWC since 2017.


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.

In 2017, IWC paired Klaus' new movement with his perpetual calendar complication, resulting in this Cal. 89630.
