First Production Year:
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".
Founded in 1868 by an American, Florentine Jones, in Schaffhausen, Switzerland, IWC is probably best known for its world-beating complicated timepieces. IWC is a fully integrated Watch Manufacture; creating and assembling its own movements, parts and watches all under one roof. IWC continues to contribute significant technical advancements in the world of watchmaking, including anti-gravity and anti-magnetic movements.
This watch is the IWC Portofino Hand-Wound Eight Days IW510103.

Two Year Warranty
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).
Gemnation utilizes a full-time Swiss-trained watchmaker who is licensed and trained to repair every brand and
model of watch that we sell. If we can supply the original warranty we provide this information in the individual
