IWC 59800

Cal. 59800 is an hand winding movement produced by IWC starting in 2017.

Details

IWC has been transitioning to in-house movements since 2000, enhancing the reputation and technical features of their watches. In 2011, IWC introduced the Cal. 59000 family of hand-wound eight day movements. This family features a single barrel and mainspring and ticks at a modern 4 Hz, making the long 192 hour power reserve extremely impressive.

Cal. 59800, introduced with little fanfare in January 2017 in the IWC Portofino Hand-Wound Moon Phase, is the only member of this family with a moon phase indicator. This complication is implemented as a module on Cal. 59210. Template:IWC 59000 Movement Family
