Owners widely praise the IWC Schaffhausen Iw3583xx Portugieser Automatic for its timeless design, comfortable 40.4mm wearability, and the Pellaton winding system of its 82200 caliber movement. Reviewers highlight the finely brushed sunray dial, applied numerals, leaf hands, and the premium feel enhanced by the double glassbox caseback. The movement itself is noted for its finishing, including perlage and côtes de Genève. Some owners find the 12.4mm case height could be thinner, and the lugs appear long, though well-curved. One owner reported the watch stopping after 6-7 hours when fully wound, contrary to the 60-hour power reserve. The 30m water resistance is considered a bare minimum for a modern watch. Overall, owners and reviewers rate the IWC Schaffhausen Iw3583xx Portugieser Automatic highly for its classic design and comfortable 40.4mm wearability at its price point.
