Elegance with power for 192 hours

There are moments you look forward to all week long. Since 2011, for many lovers of fine watchmaking, winding the Portofino Hand-Wound Eight Days has been one of them. Its IWC-manufactured 59210-calibre movement will run precisely and reliably for a full 192 hours, or 8 days, before it automatically stops. The power remaining can be read off on the power reserve display on the dial between “8” and “9 o’clock”. Together with the small seconds display at “6 o’clock” and the date display at “3”, this gives the dial a pleasing equilibrium. The indexless balance has a frequency of 28,800 beats per hour and, together with the Breguet spring bent into shape in accordance with ancient watchmaking tradition, helps to make the watch exceptionally accurate. The watch is available in a gold case with a slate-coloured or silver-plated dial and solid gold indices, or in a stainless-steel case with a silver-plated, black or blue dial with gold- or rhodium-plated indices. All models have a transparent sapphire-glass back and alligator leather straps by Santoni.

The 59210-Calibre

The newly developed 59210 calibre for the Portofino Hand-Wound Eight Days follows on in the 50000-calibre tradition: it is large, accurate and reliable, and is the first hand-wound movement from Schaffhausen with an eight-day power reserve. Actually, it would be nine days, but it is mechanically stopped before all the tension in the spring is exhausted, eliminating the effect of reduced torque in the mainspring as it winds down. This ensures greater precision the whole time the watch is running. And the owner will always be on the safe side if he winds his watch once a week. The fact that the movement is part of the 50000-calibre family is also clear from the impressive technical specifications: the indexless balance with its frequency of 28,800 beats per hour helps to ensure a high level of accuracy, as does the Breguet spring, bent into shape in accordance with ancient watchmaking tradition. There are also a power reserve display, a date display and small hacking seconds. IWC's watchmakers worked on the movement for two whole years. After thorough laboratory testing of its suitability for everyday use, it can now proudly bear IWC's own seal of quality: "Probus Scafusia" – "good, solid craftsmanship from Schaffhausen".
