The Portugieser Hand-Wound Eight Days Edition “150 Years” is a puristic Portugieser wristwatch with a hand-wound movement, featuring the design cues of the Jubilee collection. This model is limited to 1000 watches and is housed in a simple stainless-steel case. The timepiece has a white dial with a lacquered finish, and blued hands. It is powered by the IWC-manufactured 59215 hand-wound calibre. The robust movement provides a high power reserve of 8 days, so the watch needs winding only once a week. The power reserve indicator on the back of the movement is visible through the see-through sapphire-glass back. Thanks to the Breguet spring and a frequency of 4 Hertz, the balance achieves a very high level of precision.
