Additional Information
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".

We sell luxury timepieces at considerably lower prices than the manufacturers list price. Gemnation is not an Authorized IWC Watch Dealer and is not affiliated with IWC. Authorized dealers are not permitted to discount or sell watches on the Internet. For this reason, we choose not to be authorized watch dealers for many of the brands that we sell.

Since we are not authorized dealers for many of the watch manufacturers, we may be unable to ship the original watch manufacturers warranty. In all cases, however, we provide a Two Year Gemnation Warranty (active from the date of purchase).
