The 59000 family of calibres is a series of specialty hand winding eight day manufacture movements produced by IWC since 2011.
IWC has been transitioning to in-house movements since 2000, enhancing the reputation and technical features of their watches. Part of this development includes the production of specialty high-end movements. The Cal. 59000 family, like the Cal. 94000 family introduced the same year, is a large hand winding movement with long power reserve. However, unlike the double-barrel Cal. 94000, the Cal. 59000 series uses a single barrel with an unusually long, powerful mainspring. This recalls the design of Cal. 5000, IWC's first modern movement design, as does the large size of the movement.
The Cal. 59000 family includes a basic time-only movement as well as a traditional monopusher chronograph and even a tourbillon. Most feature a power reserve indicator, common on high-end hand-winding movements. All Cal. 59000 family movements oscillate at 28,800 A/h and have 192 hour power reserve.
