About this watch

The IWC Portofino Hand-Wound Eight Days Moonphase (IW5164-01) is a masterpiece of luxury watchmaking that combines exquisite craftsmanship with timeless elegance. Its polished stainless steel case shines brilliantly in the light, while its silver dial features a beautiful array of stick and dot indexes complemented by Feuille hands that glide gracefully over the surface. The moonphase indicator adds an astronomical touch at 12 o'clock, showcasing IWC's commitment to complexity and detail. The power reserve indicator lets you know how much juice you have left with a solid 192-hour reserve. The heart of this watch is its hand-wound IWC caliber 59800 movement, engineered for precision with 30 jewels and a frequency of 28,800 vibrations per hour. Additional complications include a small seconds sub-dial and date display, making the IW5164-01 not just a pretty face but a functional timepiece as well.
